#7803 Electronic Finder & Sky Catalog Model 3

Congratulations! Your Orion Sky Wizard Model 3 will put the fun back in your telescope observing. It provides a

digital readout of celestial coordinates, a database of more than 10,000 of the most interesting deep sky subjects,

and the ability to guide the observer to astronomical objects. It’s designed to work with both altazimuth (including

Dobsonian) and equatorial telescope mounts. The catalog information is stored in permanent internal memory. The

celestial subjects are organized by catalog: Messier (M), NGC and IC, plus other lesser known catalogs. Many

interesting stars are in the ST (Star) list. You can add up to 27 objects in your own NEW catalog.

Sky Wizard is designed for ease of use. Simply turn it on, sight two stars, and let it guide you to celestial objects.

There is no need to polar align the telescope, input latitude, longitude, date or time (date needed for planets). It

provides virtually any telescope with a continuous digital display of celestial coordinates. The unique method of

alignment by two star sightings provides good pointing accuracy over the entire sky.

Finding an object is easy. Just select any subject from one of the catalogs and tell Sky Wizard to find it by using

the FIND function. The display will then give instructions on how to move your telescope. You can also point your

telescope at any object in the sky, with the IDENTIFY mode, Sky Wizard will search its database and tell you the

object’s identity.

At the beginning of each observing session, you align Sky Wizard with the current sky by selecting a bright star

from the SETUP menu (list of the brightest navigational stars), pointing the telescope at that star, and then press-

ing ENTER when the star is centered in the eyepiece. The procedure requires sighting on only one star for a

polar-aligned equatorial mount, but sighting a second star will improve accuracy. An altazimuth telescope requires

two star sightings for alignment. Additional sightings made during the observing session reduce cumulative errors.

Sky Wizard weighs only 8 ounces, including the internal battery, and may be conveniently mounted near the eye-

piece. Sky Wizard connects electrically to the optical encoders with a plug-in connecting cable.The red LED display

is easy to read and does not interfere with night-adapted vision. A dimming button adjusts the brightness of the

display. Sky Wizard is especially useful under light-polluted skies where few visible stars are available to guide you

to deep-sky objects.

Sky Wizard is connected to your telescope with optical encoders. The encoders sense the rotation of the telescope

within 0.09° or 0.17°, which is precise enough to bring any object into a low-power field of view, and can track

telescope motion at rates as high as 160° per second. The encoders are attached by various methods depending

on your telescope model. Installation kits and encoders are sold separately from Sky Wizard to allow for this varia-

tion in attachment method. Instructions for mechanical installation of encoders are provided with the installation

kits.

dimmed. It can also operate from an external 12-volt DC power supply connected to the battery snap.

Installation of Sky Wizard requires an Installation Kit for your particular

make of telescope. Please refer to the instructions provided with the

Installation Kit of the encoders and other hardware.

1. Installation

The INSTALL mode is used when Sky Wizard is first installed on your

telescope. INSTALL tells Sky Wizard what kind of telescope you are

using, the desired scroll rate for the subject description display, and

the resolution or gear ratio of the encoders. This information is con-

tained in the Installation Kit’s instructions.

When entering the value of the gear ratios, you must go all the way

through the INSTALL sequence until the word INSTALL appears

again to update any changes. To start, press MODE. Scroll UP or

DOWN until the display reads INSTALL, then press ENTER.

Telescope Mount Type

The display first prompts you to select the type of telescope mount

used. The current mount type will be displayed. Press UP or DOWN

to select the desired mount.

Mount type choices:

When you have selected the correct type of mount, press ENTER to

advance to the next step.

Perfectly Aligned Option (EP or GP). For equatorial telescopes, you

can choose a ‘perfectly aligned’ telescope type if your telescope is on

a permanent mount known to be in good polar alignment, or if your

portable telescope can be easily polar aligned accurately. If you

choose a ‘perfectly aligned’ type, Sky Wizard does not ask for or

require an initial mount index, and uses only a single star to get ori-

entedwiththesky.The“Sync”functionhasnoeffect.EPorGPmode

will result in improved pointing accuracy, especially near the poles, if

your telescope is indeed perfectly aligned, by eliminating rounding

errors in the complex mathematical transformation normally needed

to adjust for polar alignment error.

Set Data Scroll Rate

This is the rate of which data scroll across the LED display window, e.g,

SCROLL 5. Set the flashing digit using the UP and DOWN buttons. 0

is very slow, 5 is about right and 9 is very fast. Press ENTER to set

your choice and go to the next step.

Select Chart Number

Sky Wizard’s database includes references to chart numbers in Wil

Tirion’s Sky Atlas 2000.0 and Uranometria 2000.0 by Tirion,

Rappaport, and Lovi, volumes 1 and 2. Choose which sky atlas chart

number you want displayed in the object descriptions.

Sky Atlas 2000.0 chart number: CHART SA

Uranometria chart number: CHART UA

Press ENTER to set your choice and go to the next step.

Encoder Settings

(See instructions w/ your install kit for correct

settings.)

The proper encoder settings (ratios) for your specific telescope mount

are located on a chart on the Installation Instructions that came with

the installation kit for your specific telescope. Simply input these

ratios in the Install mode by scrolling up and down and pressing

ENTER after each correct number that is blinking. Be sure to go all

the way through the install sequence (pressing ENTER each time)

until the word INSTALL reappears, to update any changes.

Custom Installation

(Skip this section if you have purchased an

Installation Kit for a specific telescope or you

already know the encoder ratios.)

The Sky Wizard needs to be told how many turns of an encoder indi-

cate one turn of the telescope. If you have an altazimuth telescope, or

any mount where gears or pulleys are not used, you simply need to

enter the correct resolution for your encoders. The encoder resolution

(steps per revolution) is printed on the side of the encoders you

received with your installation kit. You will either have the larger high

resolution encoders (4000 steps/revolution) or the smaller standard

resolution encoders (2160 steps/revolution). Sky Wizard will display

the preset encoder resolution for encoder #1, AZ.

Example: AZ +02160

This is the correct number for standard resolution encoders. If you

have high resolution encoders, change this number to +04000. Adjust

the blinking digit using the UP and DOWN buttons. When the digit is

correctly displayed, press ENTER to set and advance to the next digit.

After all the digits are set for the first encoder, the display switches to

the second, DEC (Altitude on altazimuth scopes): AL +02160. Set it to

the required numbers in the same way as the first. If you are installing

Sky Wizard on an equatorial mount or with any kit that uses gears or

pulleys, you will need to figure the encoder ratio for your installation

kit. If you purchased an Orion installation kit for your telescope, the

instructions for that kit will list the required encoder settings to enter in

your Sky Wizard. Simply enter those settings as described.

Determining Encoder Settings (Ratios)

You don’t need to worry about this if you know the encoder ratios from

your Installation Kit Instructions. If you are custom-installing a Sky

Wizard and need to determine the proper encoder ratios, read on. Many

mountings will utilize gears to drive the optical encoders. This can

increase resolution and make the installation more convenient. It is nec-

essary to set the ratio of each encoder to be driven by gears. If the

encoder is connected to the telescope using a belt and pulley or gears,

the ratios must be calculated. To determine the correct encoder ratios if

using gears, simply multiply the encoder resolution by the number of

teeth on the gear connected to the telescope. Divide that number by the

number of teeth on the gear connected to the encoder. For example, if

using a 4000 step encoder with an 84 tooth gear attached to it, and the

telescope axis has a 96 tooth gear attached, the final ratio would be:

4000 x 96/84=4571. If there are no gears or pulleys then the direct ratio

is 04000 (for 4000 step encoders) or 02160 (for 2160 step encoders).

Encoder Direction Test

The purpose of the encoder direction test is to make sure the encod-

ers are set to the correct polarity, correct ratios, and that nothing is

slipping. It is very important to do this test at home before trying the

Sky Wizard at night. It is the last step in the installation procedure

before going out into the field. If you find that your Sky Wizard is way

off, you must do this test before calling for assistance.

Equatorial Telescopes: Point the telescope up and slightly toward the

South so the Dec. is at 0° on the original (mechanical) setting circles.

Rotate the original RA (mechanical) setting circles so RA=00. Turn Sky

Wizard off, then back on to clear it and press ENTER after Sky Wizard

reads DEC=0. Press MODE and scroll to ENC TEST mode. Press

ENTER and it should read ER=000, ED=+000.

Move the declination axis to 90° north. The display should now show

“ER=000 ED=+090”iftheDECaxis“sign”iscorrect.Ifnot,re-enter

the INSTALL mode and change the sign to negative for the DEC axis

(AL). If the numerical value is not ED=090, then the encoder ratio is

incorrect. Check your Installation Instructions to see if you have input-

ted the correct encoder ratios in the INSTALL Mode.

To check the RA axis, again point the telescope up and slightly toward

the South so the Dec. is at 0° on the original (mechanical) setting cir-

cles. Rotate the original RA (mechanical) setting circles so RA=00.

Turn Sky Wizard off, then back on to clear it and press ENTER after

the Sky Wizard reads DEC=0. Press MODE and scroll to ENC TEST

mode. Press ENTER and it should read ER=000, ED=+000. Move the

telescope toward the Western Horizon so the RA=18 Hrs. and it

should read ER=090 ED=+000. If it reads another value, such as

ER=270 then go back to the INSTALL and change the +/- sign and

repeat the test. If you get any other values, check the encoder ratios

in INSTALL mode. Also check that the encoder and hardware are

properly installed. Make sure all setscrews are tight.

Altazimuth Telescopes: Turn on Sky Wizard and position the tele-

scope vertically as requested by the instrument in AV (telescope type)

or horizontal in AZ. Press ENTER, then the Mode button. Scroll to the

ENC TEST mode to display encoder angle. In AV mode, tilt the altitude

axis down approximately 45° from vertical. Move it up 45° in AZ. Check

thatthe display shows“AZ=000AL=+045”.If thedisplayisin agree-

ment with the telescope position, then the altitude encoder polarity is

correct and no change to the gear ratio is required. If not, press the

MODE button, scroll to INSTALL, press ENTER. Repeat the Install

procedure until you get to the encoder ratio AL=+045.Then change the

+ sign to a - sign. Be sure to go all the way through the install mode

until the word INSTALL reappears to update the changes.

Press the MODE button and scroll to ENC TEST and press ENTER.

Move the telescope about the azimuth bearing from North towards

East. The azimuth should increase from 0° to 90° if you rotate the

telescope 90°. The display should now read “AZ=090 AL=-045”,

where the 45° is from the test of the altitude axis. If the values are off,

check the encoder ratios in the INSTALL mode. Make sure the encod-

ers and hardware are installed correctly. If the AZ is off, make sure the

bottomboltisNOTrotating.Adropof“superglue”ontheverybottom

bolt and washer will help (applied from the bottom, NOT top). If the

ALT is off, make sure the altitude bearing is rigid.

Startup Index Mark

Once you have finished running INSTALL to tell Sky Wizard about

your telescope, there is one final step which need only be done one

time. As mentioned in the SETUP command, you will see that your

telescope mount needs to be aimed to a particular position once each

time you set up to observe. The accuracy of Sky Wizard is dependent

upon your accurately setting the initial index mark, so take your time.

Equatorial Mounts: If your telescope has an Equatorial mount with

mechanical setting-circle dials, these will do nicely. First, verify the

declination setting circle is accurately set by aiming your telescope to

90° declination (telescope aimed up the polar axis). Rotate the tele-

scope in Right Ascension and look for any tube “wobble”.You can

verify this by looking through an aligned finder to see that stars rotate

around the middle of the field of view. If necessary, adjust the tube so

there is no wobble and reset the setting circle to 90°.

Another method for Fork Mounted Equatorial telescopes is to check

the Dec. Setting Circle using a bubble level. This should be done

inside using a carpenter’s level, before going out into the field. Take

the telescope off the wedge and put it on a level surface. Make sure

the drive base is level and the telescope is pointed straight up with

the corrector end away from the drive base and the Dec.=90. Place

the level across the front of the corrector cell, perpendicular to the

fork arms. Adjust the Dec. slow motion until it is level. Adjust the Dec.

setting circle to read exactly 90.

German-type Equatorial Mounts: These mounts have two possible

positions for the 0° declination setting required during initialization. It

is important to use the correct one, or the encoder sensing will be

backwards. The telescope should be aimed generally EASTWARD

when the declination is set to 0°. Determine which of the two zero

degree index marks corresponds to this direction and place an indi-

cating mark there for future use. You can confirm that the setting

circles are accurate by pointing the telescope exactly North. Rotate

the telescope in RA only. Stars should rotate about the center of the

field of view. When this is achieved by adjusting the Dec. slow motion,

move the Dec. setting circle to exactly 90.

For Altazimuth or Dobsonian Telescopes: Put a simple index align-

ment mark on your scope to save time in the future. You can choose to

make the index mark with the telescope aiming either vertically or horizon-

tally, depending on your choice in the INSTALL mode. A precisely vertical

orientation can be determined by rotating the telescope around the base

and looking for any tube “wobble”.  Better yet, use a carpenter’s level.

at exactly the Vertical position. Alternately, a horizontal orientation can be

made by placing the telescope base on a very level surface, and then

leveling the telescope tube with a carpenter’s level. Mark a line on the

telescope bearing and on the body to use for an index mark.

2. Operation

Overview

Sky Wizard has nine operating modes. Each mode or function runs a

computer program to perform a different task. Pressing the MODE

button shows the current mode. Change to a different mode by press-

ing either SELECT (up or down arrow) button. The SELECT buttons

are always used for scrolling through the list of available choices. The

UP button advances through the list in a forward direction, the DOWN

button moves backwards.The operating modes are: (Note: these are

not in order of display.)

CATALOG Display or choose an object in one of the catalogs.

ENC TEST Test mode - verifies encoder rotation & correct

installation.

FIND Tell Sky Wizard to display direction/distance to

the last object chosen in one of the catalogs.

IDENTIFY Identify the object (or nearest object) that your

telescope is pointing at.

INSTALL Run when you first install Sky Wizard on your

telescope.

TIMER Use the built-in utility timer.

Power On Initialization

When you first turn on Sky Wizard, you need to aim the telescope to

a particular position so the angle of one encoder to the telescope is

known. This step is critical to accuracy. Depending on the type of mount

you have, the display shows one of the following messages: DEC=0,

LEVEL ME, or VERTICAL.Only with a perfect polar alignment (EP or

GP) does the Sky wizard go directly to SETUP.

Turn on Sky Wizard. It will briefly display the startup message ORION

SKY WIZARD V 3.51. The numbers displayed are the software version

number. Sky Wizard will display one of the following depending on the

mount type choice you made when you ran INSTALL. (See Installation,

page 4, for more information).

SET DEC=0: (Equatorial mount) Set telescope declination to the 0°

index mark, on the mechanical setting circles. You must verify that

your mechanical setting circles are exact your first time out. Aim tele-

scope at celestial equator, 90° from the pole. (German Equatorial

mountings must have the encoder initialized with the declination axis

set at the east of the meridian zero declination, the optical tube on the

West side.)

SET LEVEL ME: (Altazimuth mount type AZ) Aim telescope tube

horizontally to your index mark (telescope aimed at the horizon if

scope base is level). The telescope tube must be exactly parallel with

the bottom of the rocker box. You must verify this is exact with a

bubble level your first time out.

SET VERTICAL: (Altazimuth mount type AV) Aim telescope tube

vertically to your index mark (telescope aimed directly overhead if

scope base is level). The telescope must be exactly perpendicular to

the bottom of the rocker box. You must verify this is exact with a

bubble level your first time out. After you have moved the telescope

to the correct initial position, press ENTER. Sky Wizard will then

switch to SETUP mode. (If you make a mistake in initializing the

mount alignment, turn Sky Wizard off and on again to restart. There

is no other way to repeat mount initialization.)

The initialization steps above are critical to the pointing accuracy of

the Sky Wizard. For example, an error of 1° on the initialization will

result in errors of up to 2°. To assure accurate initialization, follow the

steps carefully in Startup Index Mark.

SETUP Star Alignment

Before Sky Wizard can tell you where to point your telescope, it

needs to get its bearings on the sky. You must do this at the start of

each observing session. SETUP mode automatically accesses a

short list of 30 named navigational stars. The brightest stars from

both the Northern and Southern hemispheres are included. These

familiar bright stars cover the sky so at least two are visible at any

time. You’ll need to point your telescope to two known stars, tell Sky

Wizard which ones they are, and you’re ready to go.

To perform the setup star alignment:

1. Pick a bright known star from the list and center it in the eyepiece.

2. Press MODE. If SETUP is not displayed, use the arrow keys to

display SETUP. Press ENTER.

3. Scroll through the star list to find the name of the star that is cen-

tered in the eyepiece, then press ENTER.

4. Choose another bright star for the second alignment star and

repeat steps 1-3.

5. For best results the two stars should be at least 60° apart. Avoid

stars near the pole.

Note: only one star sighting is required for perfectly polar-

aligned equatorial telescopes; however a second sighting is

recommended.

After Sky Wizard determines the transformation resulting from star align-

ment, it displays a measure of how well the alignment agrees with the

stardata.This“warpfactor”is0.0forperfectalignment,butanaccept-

able range is ±0.6. The display will show the warp for about 2 seconds.

This represents the error in degrees and tenths. Example: WARP=+0.4.

If the warp factor is greater than ±0.6, check to be sure you have correctly

identified the setup stars and repeat the setup operation. Make sure that

your Startup Index Mark is exact. Never assume, for example, that the

mechanical setting circles are exact for the Dec.=0 index mark. Always

double check the accuracy of the index mark, especially on your first night

out. If the warps are larger than ±10, check the encoder polarity and

encoder ratios on your installation kit instructions. Always do the ENCTEST

(Encoder Direction Test, see page 5) after installing Sky Wizard, before you

go out at night for the first time. (Note: if your telescope mount does not have

the two axes perfectly set at 90° apart, it may be impossible to reach an

acceptable warp factor. If this happens, correct the telescope mount.)

ENC TEST

Encoder test must be done after installing Sky Wizard on the tele-

scope, before going out at night for the first time. This allows

verification that the encoders are functional and move the correct

direction and amount. The unit of measure is whole degrees. For an

equatorial mount the display will show ER=000 on the right ascension

axis, and ED=000 on the declination axis. The RA decreases from 0

to -90 as you move West. The Dec. increases from 0 to +90 as you

move the telescope from the Equator to the North Pole.

For an altitude/azimuth telescope mounting, the display identifies

AZ=000 as the azimuth axis, and AL=000 as the altitude axis. Azimuth

should be 0° for logical north, and increase to 90° for logical east.

Altitude is 0° when horizontal and +90° when vertical. Motion of the

telescope will change the encoder angles. For more details, see

Encoder Direction Test (on page 5).

RA/DEC

Displays right ascension and declination, which provides a continuous

display of telescope position. Example: RA=0742 D=+28.1.This example

shows a right ascension of 7 hours and 42 minutes, and a declination of

north 28.1 degrees (Note: the final digit in the declination is in tenths of a

degree.) Pressing ENTER will momentarily show the chart number of the

Sky Atlas 2000.0 sky map that covers the part of the sky where the tele-

scope is currently pointing. Example: SA=08.

CATALOG

This mode retrieves information from one of Sky Wizard’s nine sepa-

rate catalogs. Select this mode by pressing MODE, then either UP or

DOWN until CATALOG is displayed, then press ENTER. Press the

UP or DOWN arrows to select one of the catalogs, then press ENTER

when the catalog you prefer is displayed.

Catalogs available (and typical display):

Star catalog: ST001

NGC catalog: NGC0001

IC catalog: IC0001

Non-Stellar catalog: NS001

ESO catalog: E000-01

UGC catalog: U00001

NEW (programmable) user’s catalog: NEW01

The Planets catalog: PLANETS

The first time a catalog is used the display will show its first entry. For

example, the Messier catalog displays M001, which happens to be

the Crab Nebula. The “M” will be blinking.

The ST (Star) catalog contains many interesting stars, double stars

and red stars and includes all of the alignment stars. (The complete

list is included in the back of this manual.) First look up the object,

select CATALOG mode, choose ST, and enter the index number using

the arrow buttons to set the blinking digit, pressing ENTER to advance

to the next digit to be set. Press ENTER after setting the last digit and

the display will show the coordinates. For the famous double star

The NGC Catalog is the New General Catalog of deep-sky objects

compiled by the Danish astronomer J.L.E Dreyer more than 100 years

ago. It contains hundreds of excellent examples of each type of deep-

sky object and is the most well known and used catalog by amateur

astronomers beyond the already mentioned Messier (M) catalog.

The IC Catalog, the Index Catalog, contains objects which were

discovered in the decade or so after the NGC was first published. This

list contains objects similar to the NGC, but IC objects are typically

fainter and more difficult to observe.

The NON-STELLAR Catalog contains those objects not included in

either the popular NGC or IC catalogs. Multiple sources were used to

compile this list of 661 interesting astronomical objects.

The ESO and UGC Catalogs include selections from two profes-

sional scientific astronomical catalogs.

The NEW (User’s) Catalog is initially empty. It may be used to store

the coordinates of the observer’s favorite objects, for current positions

of an unexpected comet or nova, or for a variable star observing list.

Look up the coordinates of the new object in a magazine or other

publication. There is space for 27 objects in the memory. The objects

are kept in memory even when power is turned off.

First the object number is set in the same manner as selecting any

catalog object. After the object is selected, press ENTER and the

coordinates will be displayed. If you want to change the coordinates

press ENTER again. The first digit of the coordinates will blink, this

digit may be changed by pressing the UP and DOWN buttons to

increment or decrement the digit. When the first digit is set press

ENTER to go on to the next digit. Should you decide not to change

the coordinates, press MODE to exit. When you have finished setting

the digits, press ENTER, then MODE to exit or UP or DOWN to go to

another entry in the catalog.

Example CATALOG display for selecting an object from the NEW catalog:

Enter number: NEW15

Coordinates: 1930+275

The PLANETS Catalog consists of the major planets of the solar

system. The planetary positions are calculated according to the date.

While the date is not required for any other type of celestial subject,

it is necessary for calculating correct planet positions. Sky Wizard will

remind you to enter the date the first time you choose the Planets

catalog during an observing session.

Press MODE, scroll to CATALOG, press ENTER. Scroll to PLANETS

and press ENTER. When DATE appears, press ENTER twice. The

last calendar date entered will be displayed. This date is used in the

planetary orbit calculations. The range of years is from 1950 to 2050.

Press ENTER again. The display order is Month, Date, and Year. The

digits may be set sequentially using the UP and DOWN buttons to set

each digit. Press ENTER when each digit is set to the desired value.

After setting all the digits of the date, press UP or DOWN to select a

planet.The UP and DOWN buttons will allow you to scroll through the

list of planets. Press enter to display the current coordinates of the

planet.

FIND

The FIND mode provides steering directions to a pre-selected object

in the catalog. Pick an object from any of the catalog databases, then

press MODE to return the mode selector, and press UP or DOWN

until FIND is displayed, then press ENTER. FIND takes the last object

selected from the CATALOG, compares the object’s published coor-

dinates with the current telescope position, and displays steering

directions. The unit of measure is degrees from the current position.

Suppose, for example, we selected M27, but the telescope got

bumped a few degrees before we could see it. Use the FIND mode

and move the telescope as indicated to make the displayed deviation

zero. The example below shows 2.3 degrees left and 1.5 degrees up.

As you move the telescope, the numbers will count down until the

object is re-centered and the distance displayed is 0.0 degrees. If the

distance back to the object is greater than 10 degrees in either direc-

tion, the steering will be in whole 1 degree increments. Once the

object is within 10 degrees of center the instrument will display finer

resolution steering directions of 0.1 degrees. The following sequence

of guiding displays shows how the guiding arrows and digits change

as the object is approached and then passed.

The guide mode displays guide directions based on the axes of

motion of the telescope mount. Thus an altazimuth mount will be

directed by the pointing arrows right, left, up, and down. Motion in one

axis will not cause the other deviation display to change.

Scrolling UP or DOWN while in FIND mode will tell Sky Wizard to

move in the previously selected catalog database.

If your telescope has a German-type equatorial mount, Sky Wizard

allows for the two possible ways to point at an object. Sky Wizard will

display the path from the current position that involves the least turn-

ing. Should the observer want to “flop” the telescope 180°, Sky

Wizard will guide you to that position as well.

IDENTIFY

The IDENTIFY mode provides another way to locate objects. Simply

point your telescope at any object and ask Sky Wizard to search its

database for an identity. This feature is particularly useful when

observing is restricted by cloud or sky conditions. The IDENTIFY

mode also allows you to enter a selection criteria: first, you may tell

Sky Wizard to search either all of its catalogs, or to search by the

object type of your choice. Then, tell it what magnitude to search for

by scrolling to any magnitude between 1 and 17. If you choose ANY

and Magnitude 17, it will search the entire database. This will proba-

bly include objects that are too faint to see with your telescope and

observing location. The display blinks every time it updates the

search, so if you are moving around in the sky while in the IDENTIFY

mode, it will provide information on the current, or nearest, object that

the telescope is pointed at. To do this, press Mode and scroll to

IDENTIFY. Each search takes about 3 seconds.

IDENTIFY choices:

Identify any type of object IDENT ANY MAG 10

Identify the star of Mag. 10 IDENT ST MAG 10

Globular cluster: IDENT GC MAG 10

Open cluster: DENT OC MAG 10

Galaxy: IDENT GX MAG 10

Planetary nebula: IDENT PN MAG 10

Nebula: IDENT NB MAG 10

Double star: IDENT 2* MAG 10

Red or colored star: IDENT R* MAG 10

In this example, we are searching for a double star, magnitude 6:

Set criteria: IDENT 2* MAG 10

Press ENTER to start search: SEARCHING

FOUND ST062

Press ENTER for description: ST062 MAG=5.8 SIZE=2.0

h162 PERSEUS TRIPLE STAR

CHALLENGE UA=061

When no object fits the search parameters, the first item in the cata-

log is displayed, (e.g. FOUND NGC0001)

TIMER

The Timer is a stopwatch function which measures elapsed time in

hours, minutes, and seconds. It is a real convenience to have an illumi-

nated stopwatch right on the telescope for observing the planets or

comets. Press the MODE button and select the TIMER option using the

arrow buttons. Press ENTER to enter the TIMER mode. Press the

ENTER button to start, stop, or reset the timer. Time is shown in hours,

minutes, seconds.

SYNC

This function is to be used only when objects are not centered in the

field of view. It allows any star or object in the database to be used for

alignment. For example, center the Messier object M37 in the eye-

piece. Enter CATALOG mode and select M37 in the Mlist, then press

MODE and scroll to SYNC mode. Press the ENTER button to choose

this as a new alignment fix. This function is useful for obtaining a new

alignment fix during the middle of an observing session to correct

small coordinate errors that may accumulate due to slight misalign-

ments of the encoder installation. When you SYNC, Sky Wizard will

display the object as a reminder. Example: SYNC M037. If you SYNC

with the wrong subject, Sky Wizard may become disoriented and you

will need to run SETUP again to re-orient accurately to the sky.

3. Sample Observing

Session

Power On & Setup Alignment

Let’s pretend we are observing through our telescope with an equatorial

mount, not perfectly polar aligned. We turn on the Sky Wizard. It will

briefly display the startup message ORION SKY WIZARD V3.51 (3.51 is

the software version number - your unit may have a larger number).Then

it will display DEC=0, this indicates that you need to point the telescope

to declination equal to zero (using the mechanical setting circles), where

the optical axis is perpendicular to both the right ascension and declina-

tion axes. This means the telescope is pointed at the Celestial Equator.

(German-type Equatorial mountings must have the encoder initialized

with the declination axis set at the East-of-the-meridian zero declination.

Be sure to use the Dec.=0° mark which coincides with the telescope

aiming toward East.)

Press ENTER when the declination angle is set at 0°. The display will

then say MODE SETUP. Sky Wizard initially assumes that your equato-

rial telescope is properly polar aligned (EP or GP mount type), in which

case it is only necessary to sight a single star at the beginning of the

observing session. Position the telescope so that a familiar bright star is

centered in the eyepiece. Press ENTER and use the arrow buttons to

scroll through the list of 32 stars until you find the name of the star that

is in the eyepiece. Press the ENTER button again. The telescope is now

aligned. A second star may be sighted in another region of the sky to

increase accuracy in GP or EP mount types. With all other mount types,

you must sight on two stars. The first star sighting should be at least 60°

from the celestial pole, a second star should be between 60° and 120°

from the first star. It is best NOT to use Polaris for the second star.

A second star sighting is also required for an altazimuth telescope. It is

critical to ensure that the initialization index mark for either vertical or

horizontal has been checked for accuracy. This operation is described in

the INSTALL section of this manual.

For our example, we will use Regulus, the bright star at the base of

the backward question mark of Leo. In the SETUP mode, press

ENTER, the display will show the first star name in the list of 31 bright

stars. The first star in the list is Achernar, and the display will read

ALIGN ACHERNAR.

Using Regulus for our first star sighting, press the UP arrow button to

advance through the list of star names (scroll to the star you want). If you

went past Regulus while scrolling, simply press the DOWN arrow button

to back up. Release the button when the display reads REGULUS.

Press ENTER when Regulus is in the center of the field of view. Verify

the star is still centered in the eyepiece and press the ENTER button

to complete the alignment. The display will show the warp factor which

is a measure of the amount of agreement between the catalog angles

and the measured angles between sighted stars. WARP=-0.6.

Sighting a second star will improve accuracy, especially if there are any

alignment errors in the polar mounting. For optimal coverage of the sky,

pick a second star that is between 60° and 120° away from the first star.

After the first star sighting, simply press one of the arrow buttons to

advance to another star name. To find Mizar, for example, press the UP

arrow button until the display reads MIZAR. Center Mizar in the eye-

piece and press the ENTER button. The second star sighting is now

complete. Press the MODE button to exit SETUP.

Press UP or DOWN to select the RA DEC mode for display, then

press ENTER. Sky Wizard will now display the celestial coordinates

for any telescope position. In our example the display now reads the

coordinates for Mizar since that is where the telescope is currently

pointed. The display reads RA=1324 D=+54.9.

Swing the telescope around and observe how quickly the instrument

tracks the telescope position. The high resolution encoders are very

sensitive to small motions. Sky Wizard can track motions as great as

100° per second, which is faster than you would probably move a deli-

cate optical instrument. Sky Wizard locks on to the current position

instantly and provides a steady display of the computed celestial coordi-

nates.

RA/DEC Mode

Let’s do some observing. We have a long session ahead if we want

to view all the Messier objects, over 300 interesting stars and the

entire list of user catalog objects. Fortunately, Sky Wizard will make

the search quite easy. It’s time to use the powerful database and the

smart function called FIND.

To start, let’s just stay in RA DEC mode and swing the telescope

around to one of our favorites, M37 in the constellation Auriga. The

coordinates are 0552+326. We are currently positioned on Mizar at

1324+54.9. Experiment by moving the telescope around to increase

and decrease the two coordinates. Take a couple of minutes to master

this action as you become familiar with the relationship between the

telescope coordinate system and the celestial coordinate system.

When the display reads “RA=0552 D=32.6,” take a look through the

eyepiece. M37 is right there, a nice galactic cluster with red giant stars,

proof that the installation is functioning correctly and that the alignment

stars were carefully centered in the eyepiece during alignment.

Using the CATALOG

Now that we are pointed at M37, we would like to see the other Messier

object M36, but we forgot to bring our charts and handbooks. Press

MODE and select CATALOG, then press ENTER. We are now in the Sky

Wizard database. The display shows M001 when we enter this mode.

Press ENTER to choose the Messier catalog, then press the UP or

DOWN select buttons to enter the number 036. We set one digit at a time,

much like a digital wrist watch, by changing the value of the blinking digit.

CATALOG initial setting: M001

Setting digits to M36: M036

Press the ENTER button to advance to the next blinking digit and use

the UP or DOWN buttons to increment or decrement the value. Press

ENTER after setting the last digit and the display will show the coor-

dinates.

M36 coordinates: 0536+341

M36 scrolling description: M036 MAG 6.0 SIZE=11 AURIGA

OPEN CLUSTER RICH SA=05

We now have the coordinates for M36. There are two ways to go from

here. We can remember the coordinates and switch to RA DEC mode

to steer the telescope, or use the FIND mode to give us steering

directions to the object from our current position. The FIND mode

indicates just how much motion is required for each axis of rotation.

Using the FIND Function

Press the MODE button and select FIND, using the arrow buttons to

scroll through the choices. The instrument remembers the object

“M036” as the last item selected, and shows the steering distances

in degrees from our current position. FIND shows 6c4 17a, indicating

that M36 lies 17° down and 6.4° to the left of our current position.

When the object is centered the distances displayed will be zero.

FIND directions: 6ﬁ4 17ﬂ

Object centered: 0•0 0•0

While in FIND mode, with M36 centered, press the ENTER button

again to see the name of the object which is of course M36. This

observing session is off to a good start.

Using the SYNC Function

While observing we notice that most of the objects are off toward the

same edge of the field of view when we zero the FIND display.

Probably we bumped the telescope base or were off a little when we

sighted a star. Another possibility is that the initialization was not

done correctly. We can have Sky Wizard slightly adjust the alignment

by simply centering the last object we located with FIND, then press

MODE and select SYNC, then press ENTER. The next object should

then be more accurately centered.

If SYNC makes things worse, you may have been aiming at the

wrong object. Just turn off Sky Wizard and align again from scratch.

4. Computer Interface

RS232 Computer Interface

Sky Wizard may be connected to your per-

sonal computer with a serial cable. This

allowsyoutousesoftwaresuchas“TheSky”

from Software Bisque or other compatible

software programs. This interface operates

independently from the normal functions. The

system responds to requests from your com-

puter and provides the encoder angles. The

software is responsible for transforming the

encoder angles into celestial coordinates.

RS232 Connections

A 6-position modular connector is used for RS232 interface. There are

a few computer accessories that have a compatible cable. The inter-

face cable is available separately. The cable used only 3 pins of the

6-position modular connector. Be careful to check the quality of a crimp

when low cost crimpers are used. Make sure all the pins are down

before inserting into the instrument, as this can damage the wires of

the connector.

Wire Signal DB25 DB9

yellow TX 2 2

green RX 3 3

red gnd 7 5

black +9 to 12 nc nc

You can make your own, only 3 wires used; TX, RX, ground. You will have

to check your computer manual for the connections on that end of the

cable. The TX pin at the computer must connect to the RX pin on the Sky

Wizard. The RX pin at the computer must connect to the TX pin on the Sky

Wizard. The ground (gnd) pin is connected straight across. The communi-

cation is at 9600 baud, 8 data bits, 1 stop bit, no parity. The transmitter

depends on the personal computer providing a mark state, -5 to -12 volts,

when idle.

RS232 Commands

The serial data RS232 signals are provided in the simplest form.There are

only 3 wires that transmit, receive, and ground. A 6-position modular con-

nector is used. It will be easier if the colors are connected as indicated. Be

careful that the connectors at both ends of the modular wire are con-

nected straight-through, not crossed. The connection is most easily made

by using a modular to D-connector adapter available at electronic stores.

If it does not talk to your computer, try reversing the TX and RX wires.

The serial communication is very simple. Set up the computer to oper-

ate at 9600 baud, no parity, 1 stop bits. The instrument responds to

onlytwocommands.Thesecommandsareeachjustoneletter.“Q”is

a query, the instrument responds with the position of the telescope as
