TABLE OF CONTENTS
Follow the instructions for your specific
model in the manual. Read the entire instructions
carefully before beginning. Your telesope should
be assembled during daylight hours. Choose a
large, open area to work to allow room for all
parts to be unpackaged.
Before you begin
If you are interested in submitting telephotographs taken with
Sky-Watcher telescopes, or articles concerning any Sky-Watcher
products, please call us at 604-241-7027.
Canada: 604-270-2813
between 9:00AM and 3:00PM PST
Outside Canada: Please contact your dealer for
technical support.
Technical Support
Never use your telescope to look directly at the sun.
Permanent eye damage will result. Use a proper solar
filter for viewing the sun. When observing the sun,
place a dust cap over your finderscope to protect it
from exposure. Never use an eyepiece-type solar filter
and never use your telescope to project sunlight onto
another surface, the internal heat build-up will damage
the telescope optical elements.
Caution!

ATTACHING THE ACCESSORY TRAY (2)
1) Locate tripod leg brace.
2) Use the screws already attached to the hinges to mount the tray platform.
3) Secure the accessory tray on top of the tray platform using the
thumbscrews already attached.
ATTACHING MOUNT TO TRIPOD (1)
1) Locate Tripod legs and AZ mount/tripod head.
2) Fasten tripod legs to the bottom of the mount using bolts and wingnuts
already attached to the top of each tripod leg. Align the tripod legs so
that the hinge for the accessory tray faces inwards.
Note: To level the tripod, slacken the locking thumb screws on the
side of the tripod leg and adjust the length of the legs.

INSTALLING COUNTERWEIGHT (3)
1) Loosen latitude adjustment knob on side of equatorial
mount and rotate top-half of mount into an upright position.
The large scale (setting circle) should be vertical and the
mounting bracket for the telescope tube should be at the top.
2) Slide counterweight halfway onto rod. Hold the counterweight
with one hand and insert counterweight rod into threaded hole
on mount with the other hand. Tighten counterweight
rod onto mount.
3) Tighten thumbscrew to lock counterweight in place.
INSTALLING CONTROL CABLES (4)
1) Locate the control cables. The control cables
have two different lengths. Although you can
mount either cable to each direction axis, it is
recommended that you mount the longer
cable to the declination axis and the shorter
cable to the right ascension axis (setting circle).
2) To install the control cables, slide the sleeve
end of the cable over the nipple on the end
of the worm gear. Tighten the cable using the
set screw against the flat surface on the nipple.

the Finderscope
1) Focus the telescope eyepiece on a distant object.
2) Once the object has been centered in the telescope
view, ensure the locking screws are tightened.
3) Use the three alignment screws to center the
finderscope crosshairs on the object seen in the
telescope view (Fig.a).
Depending on telescope design, the object may appear
inverted in the telescope view.
Do not over-tighten the three alignment screws
on the finderscope mount.
OPERATING YOUR TELESCOPE
Fig.a
Telescope should be balanced before each observing session. Balancing reduces stress on telescope mount
and allows precise control of micro-adjustement. A balanced telescope is specially critical when using the
optional clock drive for astrophotography.
The telescope should be balanced after all accessories (eyepiece, camera, etc.) have been attached. Before
balancing your telescope, make sure that your tripod is balanced and on a stable surface. For photography,
point the telescope in the direction you will be taking photos before preforming the balancing steps.
R.A. Balancing
1) Adjust altitude of the mount to between 15º and 30º by
using the altitude adjustment T-bolt.
2) Slowly unlock the R.A. and Dec. lock knobs.
Rotate the telescope unitl both the optical tube
and counterweight rod is horizontal to the ground,
and the telescope tube is to the side of the mount. (Fig. b)
3) Tighten the Dec. lock knob.
4) Move counterweight along counterweight rod until
telescope is balanced and remains stationary when released
5) Tighten counterweight thumb screws to hold the counterweight
in its new position.
Dec. Balancing
All accessories should be attached to the telescope before
commencing with balancing the declination axis. The R.A.
axis should be balanced before proceeding with Dec. balancing.
1) Adjust altitude of the mount to between 60º and 75º.
2) Release the R.A. lock knob and rotate R.A. axis so that the
counterweight rod is in horizontal position. Tighten the R.A. thumbscrew.
3) Unlock the Dec. thumbscrew and rotate telescope tube until it is paralled to the ground.
4) Slowly release telescope and determine which direction the telescope rotates. Loosen
telescope tube rings and slide telescope tube forward or backward in the clamps
to balance Dec. axis.
5) Once telescope no longer rotates from its parallel starting position, re-tighten tube rings
and the Dec. lock knob. Reset altitude axis to your local latitude.

OPERATING YOUR TELESCOPE
To magnify images in the telescope, you need to insert an eyepiece (ocular) into the end of the focuser
assembly. Insert the desired eyepiece and lightly tighten the thumbscrews to hold the eyepiece in place.
Barlow lens can be used to increase magnification of the eyepiece. Install the barlow lense directly into
the end of the focuser, then insert the eyepiece into the barlow lense. (Fig. f)
To locate an object in the eyepiece, first locate the object in the
finderscope view. The finderscope allows magnification of a
larger area than the higher power telescope view. Finderscope
should be aligned during daytime before use.
The focus knobs at the base of the focuser uses a rack-and-pinion
system to focus the magnified images seen through the telescope.
Turn the knobs slowly until the objects are in focus.
Using the oculars
Replace the dust cap over end of telescope whenever not in use. This prevents dust from settling on mirror
or lens surface. Do not clean mirror or lens unless you are familiar with optical surfaces. Clean finderscope
and eyepieces with special lens paper only. Cleaning and aligning of optical elements should be preformed
by an experienced technician every two years. Eyepieces should be handled with care, avoid touching
optical surfaces.
Telescopes require about 30 minutes to equalize with surrounding temperature and humidity. This minimizes
heat wave distortion inside telescope tube and allows telescope to adapt to ambient moisture conditions.

the EQ2 mount
The equatorial mount has controls for both conventional
altitude (up-down) and azimuthal(left-right) directions of
motion. These two directions are recommended for large
direction changes and for terrestial viewing. Use the large
knurled knob near the base of the mount for azimuthal
adjustments, and the altitude adjustment T-bolts for altitude
adjustments. (Fig. c)
In addition, this mount has right ascension (hour angle) and
declination direction controls for polar-aligned astronomical
observing. Loosen the lock knobs to make large direction
changes. Use the control cable for fine adjustment after the
lock knobs have all been locked. (Fig. d)
