How To Set Up
Note: We recommend assembling your telescope for the first time in the daylight or in a lit room so
that you can familiarize yourself with assembly steps and all components.

How to set up
Note: We recommend assembling your telescope for the first time in the daylight or in a lit room so
that you can familiarize yourself with assembly steps and all components.
1. Open the tripod until the tripod spreaders are fully extended.
2. To set the tripod height, unlatch the hinged locking mechanisms on each leg and extend or retract the
leg to the desired setting.
3. When the tripod is the proper height, relatch any open locking mechanisms on each leg before
attaching the telescope tube.
4a-b. Set the telescope tube on the mount head so that the thread is aligned with the locking screw in
the centre of the mounting plate. Secure the tube to the mount by tightening the locking screw until it is
secure. Be careful not to
over-tighten the locking screw.
5a. Slide the red dot viewfinder into the finder bracket that is already mounted on the telescope tube and
insert the diagonal into the focuser.
5b. Secure the diagonal by tightening the focuser thumbscrews. Place your chosen eyepiece into the
diagonal. We recommend starting with the 20 mm because it will provide the widest field of view.
6a-b. To move the telescope up or down and left or right, loosen the handle. Move the telescope up or
down, left or right and tighten the handle to lock it to the desired position.
Using/aligning the red dot viewfinder:
The viewfinder is powered by a CR-2032 battery that is included. Before using the viewfinder for the first
time, remember to remove the plastic insulator that is blocking the battery from connecting. When it is
time to replace the battery, remove the battery cap by loosening the set screw. Take out the old battery
and slide a new battery in place with the positive side showing. Replace the cap, and tighten the set
screw.
Note: Please recycle used batteries
responsibly.
For the viewfinder to be
effective, it must be aligned.
To do this:
Insert the 20 mm eyepiece into the diagonal
and power on the viewfinder by sliding the
switch on its right side to an “On” position.
7a. Point the eyepiece at an easy to identify
target like a tree that is approximately
200 yards away. Centre the object in the
eyepiece. Lock the telescope into place by
tightening the panhandle.
Note: Terrestrial objects will appear
reversed due to the optical setup. This
rotation is perfectly normal for a refractor
using a standard diagonal, and it will not
affect astronomical viewing.
7b-e. Without moving the telescope, position the red dot using the two adjustment screws so that it
shares the same view as the one in your eyepiece. The front screw will move the viewfinder up and down,
and the other will move it side to side. Your viewfinder is now aligned.
8. Telescope is ready for viewing.
The Red Dot Viewfinder is
powered by a battery type
CR-2032 (3V); if a replacement is
necessary, remove cap (Fig. 1) by
unscrewing set screw (Fig. 2) and

Using Your Telescope:
After you have aligned your viewfinder, you are ready to start observing! Put the 20 mm eyepiece into
the focuser to get the widest field of view. This wider field of view will make it easier to locate and track
objects. Use the panhandle to move the scope up, down and side to side until your target comes into
view in the eyepiece. It is important to remember that the rotation of the Earth means objects will move
out of your eyepiece fairly quickly. Once you have found and focused on your desired target, you can
track it as it journeys across the night sky using the panhandle.
To get a closer look at an object, take out the 20 mm eyepiece and replace it with the 12.5 mm eyepiece.
This will increase the magnification to 48x. For the strongest magnification, take out the 12.5 mm
eyepiece and insert the 2x Barlow lens into the diagonal. Put the 12.5 mm eyepiece into the Barlow lens
and secure it in place, this will up the magnification from 48x to 96x. If you use the Barlow lens with
the 26 mm eyepiece, the magnification will
change from 30x to 60x.
Note: Terrestrial objects will appear
reversed due to the optical setup. This
rotation is perfectly normal for a refractor
using a standard diagonal, and it will not affect astronomical viewing.
Cleaning:
Your telescope is a precision optical device and keeping the optics free of dust and dirt is crucial for
optimal performance. To clean the lenses (objective and eyepiece) use only a photo-grade soft brush or
a lint-free cloth, like a microfibre cloth. Do not press down too hard while cleaning, as this might scratch
the lens. If necessary, the cleaning cloth can be moistened with an optical glass cleaning fluid and the lens
wiped clean using very little pressure. The eyepiece is NOT waterproof so do not spray fluids directly
onto the glass or dip it in water. Never use harsh detergents! After you have finished cleaning an
eyepiece, allow it to fully dry before storing.
Make sure your telescope is always protected against dust and dirt. After use, leave it in a warm room to
dry off before storing.
Troubleshooting Guide:
Problem Solution
No picture Remove dust protection cap.
Blurred picture Adjust focus using focus wheel.
No focus possible Wait for temperature to balance out.
Bad quality Never observe through a glass surface such as a window.
Viewing object visible in the finder, but
not through the telescope Align finder to telescope (see instructions)
Despite using star diagonal the picture
is “crooked”
The star diagonal should be vertical in the eyepiece
connection.

Observing Tips:
Star hopping
Star hopping is a technique used by amateur astronomers to navigate the night sky. By using easily
recognizable constellations and asterisms as a guide, an observer can locate stars and other objects.
For example, Polaris, which is
commonly referred to as The
North Star, can be located quickly
using star hopping. First, find the
Big Dipper asterism in the Ursa
Major constellation. The popular
pattern is defined by seven stars,
and the two stars on the front
edge of the Big Dipper’s “bowl”
are Merak and Dubhe. Next, draw
an imaginary line from the bottom
star (Merak) on this front edge
through the top star (Dubhe) on
the front edge. Follow the line to
the first bright star you see. That
should be Polaris. Finally, to verify
your finding, locate the Little
Dipper asterism. Polaris is the
anchor star at the end of the Little Dipper’s “handle.”

Possible Objects for Observation:
What you can observe at any one time in your telescope depends
on several factors beyond aperture and magnification. These
factors include location, date, time and sky conditions. The
following are all objects that can be seen with the unaided eye
and/or binoculars. Your telescope can enhance views of any of
these objects if the observing conditions are right.
The Moon:
Diameter: 3,476 km
Distance: Approximately 384,401 km
The Moon is the Earth’s only natural satellite, and it is the second
brightest object in the sky (after the Sun). Although it is our
closest neighbor, a lot of people have never really taken a good
long like at the Moon. With your telescope, you should be able to
see several interesting lunar features. These include lunar maria,
which appear as vast plains, and some of the larger craters. The
best views will be found along the terminator, which is the edge
where the visible and shadowed portions of the Moon meet.
Orion Nebula(M42):
Right ascension: 05: 35.4 (hours: minutes)
Declination: -05: 27 (degrees: minutes)
Distance: Approximately 1,344 light years
The Orion Nebula is a vast star-forming region located in the
“sword” branching off of the famous Orion’s Belt. Also known
as Messier 42, this diffuse nebula is bright enough to see with
the unaided eye — although it will only appear as a slightly
foggy star. However, with your telescope, you can see many of
the beautiful details, such as the billowing clouds of gas and
dust where new stars are being born.

Note: Images are for illustration purposes only. Quality of your image may very depending upon atmospheric conditions and location.
Note: The positioning of the Big Dipper in relation to the Little
Dipper does not change, but the orientation of both in the night sky
will rotate throughout the year due to the motion of the Earth.

Pleiades Star Cluster(M45):
Right ascension: 03: 47.0 (hours: minutes)
Declination: +24: 07 (degrees: minutes)
Distance: Approximately 444 light years
The Pleiades Star Cluster is a group of brilliant blue
stars located in the Taurus Constellation. Also known
as Messier 45 or “Seven Sisters”, this open star cluster
consists of more than 1,000 confirmed stars, although
an average of only six are visible to the unaided eye.
With your telescope, you can quickly reveal some
of the more elusive members of this legendary and
beautiful cluster.
Dumbbell Nebula(M27)
Right ascension: 19:59.6 (hours: minutes)
Declination: +22:43 (degrees: minutes)
Distance: Approximately 1,360 light years
The Dumbbell Nebula was the first planetary nebula
ever discovered. It is one of the most popular sights
in the Vulpecula constellation. Easy to find with
binoculars and amazing in a telescope, the shape of
this bright, double-lobed nebula has been compared
to a dumbbell, an hourglass or an apple core. As an
added bonus, the white dwarf that lies at the heart of
the Dumbbell Nebula is larger than any other star of
its kind.
Andromeda Galaxy(M31):
Right ascension: 00: 42.7 (hours: minutes)
Declination: +41: 16 (degrees: minutes)
Distance: Approximately 2.54 million light years
The Andromeda Galaxy is the closest major galaxy
to our own Milky Way. Also known as Messier 31, this
famous spiral galaxy is part of the Local Group of
galaxies. Although it is technically bright enough to
see with the unaided eye under a very dark sky, your
telescope may show its bright centre, hints of its spiral
structure and its much smaller companion galaxies
known as M32 and M110.

Reflector
A refractor telescope uses mirrors to gather and focus light. Light enters the telescope through its open
front end and travels to the concave primary mirror at the back. From there the light is reflected back up
the tube to a flat secondary mirror, which sits at a 45° angle in relation to the eyepiece. Light bounces off
of this secondary mirror and out through the eyepiece. A refractor telescope is designed for astronomical
use. Terrestrial objects may appear inverted, sideways or at an angle depending on how your tube is
oriented due to optical design. This rotation is perfectly normal on all Newtonian refractors and will not
affect astronomical viewing.
Refractor:
A refracting telescope uses a collection of lenses to gather and focus light. A refractor’s views will
be upside down if a diagonal is not in use. A standard diagonal will generate a “right side up” image,
however, it will rotate the image on the vertical axis (mirror image). To get the “right side up” image
without the rotation, you will need to use a special diagonal with an erect image prism.
Catadioptric:
A catadioptric telescope uses a combination of mirrors and lenses to gather and focus light. Popular
catadioptric designs include the Maksutov-Cassegrain and Schmidt-Cassegrain.
Types Of Telescopes:

10
Aperture:
This figure, which is usually expressed in millimeters, is the diameter of a telescope’s light-gathering
surface (objective lens in a refractor or primary mirror in a refractor). Aperture is the key factor in
determining the brightness and sharpness of the image.
Objective Lens:
The objective lens is the main light-gathering component of a refractor telescope. It is actually composed
of several lens elements.
Diagonal:
This accessory houses a mirror that deflects the ray of light 90 degrees. With a horizontal telescope tube,
this device deflects the light upwards so that you can comfortably observe by looking downwards into
the eyepiece. The image in a standard diagonal mirror appears upright, but rotated around its vertical
axis (mirror image). To get an image without this rotation, you will need to use a special diagonal with an
erect image prism.
Eyepiece:
An eyepiece is an optical accessory comprised of several lens elements. It determines the magnification
of a particular observing setup.
Primary Mirror:
The primary mirror is the principle light-gathering surface of a refractor telescope.
Secondary Mirror:
A secondary mirror is a small mirror that sits at a 45° angle in relation to the primary mirror of a reflecting
telescope. Light from the primary mirror is reflected back up the tube to the secondary mirror. The light is
directed from this mirror up into the eyepiece.

Telescope Terms to Know:

11
Magnification:
The magnification corresponds to the difference between observation with the naked eye and
observation through a magnifying device like a telescope. If a telescope configuration has a magnification
of 30x, then an object viewed through the telescope will appear 30 times larger than it would with the
naked eye. To calculate the magnification of your telescope setup, divide the focal length of the telescope
tube by the focal length of the eyepiece. For example, a 20 mm eyepiece in a telescope with a 1000mm
focal length will result in 50x power, which will make the object appear 50 times larger. If you change the
eyepiece, the power goes up or down accordingly.
Focal ratio :
The focal ratio of a telescope is determined by dividing the telescope’s focal length by its aperture
(usually expressed in millimeters). It plays a key role in determining a telescope’s field of view and
significantly impacts imaging time in astrophotography. For example, a telescope with a focal length of
1000mm and a 100mm clear aperture has a focal ratio of f/10.
Focal length (Telescope):
The focal length is the distance in millimeters between the objective lens or primary mirror and the point
at which entering light rays converge — otherwise known as the focal point. The focal lengths of the
telescope tube and the eyepiece are used to determine magnification.
Focal length (Eyepiece):
The focal length is the distance in millimeters between the centre of the first lens element in an eyepiece
and the focal point. The focal lengths of the telescope tube and the eyepiece are used to determine
magnification. Short eyepiece focal lengths produce higher magnifications than long eyepiece focal
lengths.
Exit Pupil :
The exit pupil is the diameter of the beam of light coming out of the eyepiece. To calculate exit pupil,
divide the focal length of your eyepiece by your telescope’s focal ratio. For example, if you use a 20 mm
eyepiece with an f/5 telescope, the exit pupil would be 4mm.

Eye Relief :
Eye relief is all about a comfortable viewing experience because it is the distance at which you need to
position your eye from the eyepiece’s outermost surface to enjoy the full field of view. This characteristic
is of special concern to observers who wear glasses to correct an astigmatism, because a long enough
eye relief is necessary to allow room
for glasses.
Huygenian Eyepieces:
A Huygenian eyepiece uses two plano-convex lenses separated by an air gap. They have a fairly narrow
apparent field of view.
Kellner Eyepieces:
A Kellner eyepiece uses three lens elements - two of which are paired together in an achromatic doublet
design to minimize chromatic aberrations. They typically produce an apparent field of view around 45°.
Plössl Eyepieces:
A Plossl eyepiece uses two doublets (a pairing of lens) for a total of four lens elements. This eyepiece
design delivers sharp views and an apparent field of view of approximately 50°, which works well for both
planetary and deep sky viewing.
Barlow Lens:
A Barlow lens effectively increases the focal length of a telescope. It is inserted between the eyepiece
and the focuser/diagonal (depending on the optical setup) and multiplies the magnification power of the
eyepiece. For example, a 2x Barlow will double the magnification of a particular eyepiece.

Observe, investigate, discover!
When you want to take your investigations to the cellular level, the 900x Microscope is ready to reveal
the hidden details of the world around you. Everyday things like sand, onion skin, hair and pollen will
show their extraordinary sides when viewed at magnifications ranging from 100x to 900x. To jumpstart
your observations, the set comes with prepared specimens, collection tools and an experiment guide.
How do I use my microscope?
Before you use your microscope, make sure that the table, desk or surface that you place it on is stable
and is not subject to vibration. If the microscope needs to be moved, hold it by the arm and base while
carefully transferring it. Once the microscope is in a suitable location and the batteries are installed, check
the light source to make sure that it illuminates. Use a microfibre cleaning cloth to gently wipe the lenses
off. If the stage is dirty with dust or oil, carefully clean it off. Make sure that you only raise and lower the
stage using the focus adjustment knob.
Install batteries
1. Remove button screws and cover.
2. Install batteries with the positive (+)
and negative (-) in the correct direction
indicated by the battery compartment
label.
3. Replace the cover and screws.
Do not mix old and new batteries. Do not
mix alkaline, standard (carbon-zinc), or
rechargeable (ni-cad, ni-mh, etc.) batteries.
Non-rechargeable batteries are not to
be recharged. Please recycle batteries
responsibly.
How do I operate the illumination?
Locate the mirror/light on the base of the microscope. Flip the mirror/light to the “on” position (with the
light facing up) and the light will illuminate. This microscope is equipped with an incandescent light that
illuminates the specimen from below.
How do I adjust my microscope correctly?
Place the microscope in a suitable location as described above, and sit in a comfortable viewing position.
Always start each observation with the lowest magnification. Adjust the distance of the microscope stage
so that the stage is in the lowest position — farthest away from the turret head. Turn the objective turret
until it clicks into place at the lowest magnification (Objective: 5x/Magnification: 100x). Note: Before you
change the objective setting, always make sure the microscope stage is farthest away from the turret by
rotating the focus knob. Separating the stage and turret by rotating the focus knob will avoid causing
damage to the specimen slide or microscope. When starting an observation, always start with the 5x
objective in the rotating head.

How do I observe the specimen?
Sitting in your location with adequate illumination chosen from the colour filter wheel, the following basic
rules should be observed. Start with a simple observation at the lowest magnification.
Place the prepared slide directly under the objective on the microscope stage and secure it with the
stage clips. The prepared slide should be located directly over the lower illumination. Look through
the eyepiece and carefully turn the focus knob until the image appears clear and sharp. Higher levels
of magnification can be achieved by turning the objective turret to a higher setting (400x or 900x).
Following this procedure creates a steady increase of magnification without overpowering the view
of the object. The following magnification order should be used: 100x, 400x then 900x. Each time the
magnification changes (due to the objective change), the image sharpness must be readjusted with
the focus knob. When doing this, be careful because if you move the microscope stage too quickly, the
objective and the slide could come into contact and cause damage to the slide or microscope.
For transparent objects (e.g. sea salt), light is projected by the lower light traveling from below the stage,
through the objective and eyepiece, and finally into your eye. This process of light transmission is known
as microscopy. Many micro-organisms found in water, plant components and the smallest animal parts
are transparent in nature. Opaque specimens, on the other hand, will need to be prepared for viewing.
Opaque specimens can be made transparent by a process of treatment and penetration with the correct
materials (media), or by slicing. You can read more about creating specimens in the enclosed microscope
experiments booklet.

The highest magnification is not always the best for every specimen!
