1. The tripod and mount come
preassembled so setting up is easy
and you would not need any tools for
setting up the telescope. It’s
recommended to set up the telescope
indoor first to get familiar with the set
up process.
2. Spread the tripod out fully (see Fig.4)
and place the tripod on a relatively
flat ground or table.
3. Attach the accessory tray onto the
center spreader bar. Lock the
accessory tray down by tightening the
screw. (See Fig.4)

4. Release the tripod leg lock (see Fig.5) and fully extend the legs. You can adjust the
tripod height by raising the tripod legs. At the lowest level the height of the dovetail
receiver is about 22”(56cm) and about 60”(152cm) at its highest level. When fully
extended, the tripod looks similar to the image in Fig.6.

1. Remove the protective paper covering
the optical tube assembly before
moving on.
2. Please note that there are two threaded
holes on the bottom of the Vixen
dovetail. (see Fig.7)
3. Locate the Vixen Dovetail on the OTA,
usually in our signature gold color and
locate the OTA lock knob on the mount
(see Fig.8).
4. Slide the OTA onto the dovetail receiver
and tighten the OTA lock knob to a firm
feel to secure the OTA onto the saddle
plate.
5. Please make sure the tighten the OTA
lock knob to a firm feel to prevent the
OTA falling off. (See Fig. 9)

1. For the 70AZ Refractor, remove the two
viewfinder locking nuts and install the
viewfinder onto the OTA. Tighten the
lock nuts back to secure the viewfinder.
(See Fig.10)
2. Remove the plastic plug at the back of
the OTA and make sure the two
thumbscrews do not protrude into the
opening of the back of the OTA before
installing the accessories. Install the
diagonal into the back of the OTA and
retighten the two thumbscrews to
secure it. (See Fig.11)
3. Loosen the thumbscrew on the opening
end of the diagonal until it is not
protruding into the opening. Insert one
of the three included eyepieces into the
diagonal and secure it by retightening
the thumbscrew to a firm feel. (See
Fig.11)
4. Use different eyepieces for different
magnifications. It’s recommended to
start off with the eyepiece with the
least power (i.e. the largest focal length
eyepiece). (See Fig.11)
5. In case of requiring even higher
magnifications, install the included 3X
Barlow Lens between the eyepiece and
diagonal to double the magnification.

1. After installing the viewfinder onto the OTA,
the viewfinder and OTA are not yet aligned.
You may not see the same object through the
eyepiece and the viewfinder. Aligning the OTA
with the viewfinder is a necessary step before
using the telescope.
2. Point your telescope at a stationary object at
distance. A STOP sign, a light pole are some
objects that often used for alignment purposes.
Use the eyepiece with the lowest power and
look through the eyepiece. Center the object
in the eyepiece and focus image.
3. Turn on the red dot viewfinder by turning the
knob in the front of the viewfinder (shown in
Fig.15).
4. By turning the knob on the right side of the
viewfinder, the red dot can be moved left and
right. By turning the knob of the back of the
viewfinder, the red dot can be moved up and
down.
5. Move the red dot so that the red dot overlaps
the object you have centered in the eyepiece.
6. You may need to repeat the same object at
night to furthermore align the OTA and
viewfinder by pointing the telescope at a bright
star or the Moon.

TELESCOPE BASICS
How to calculate Magnification
Calculating the magnification of a telescope is a very straightforward and easy
process that involves dividing the telescope’s focal length by the eyepieces’ focal
length.
The Focal length is the distance from the primary lens or the mirror to the point
where the incoming light converges. To determine magnification, simply divide the
telescope’s focal length by the eyepieces’ focal length. Here is the equation for the
calculation.
  

For instance, if your telescope has a focal length of 400mm and you’re using an
eyepiece with a focal length of 10mm, the magnification of this set up can be
calculated as shown:
  
 40X
Please keep in mind that while magnification influences the apparent size of
observed objects, it is also important to consider factors like atmospheric
conditions and telescope’s optics for a comprehensive view.

TELESCOPE BASICS
Celestial Observing
Once your telescope is set up completely, you are ready to observe any terrestrial
and celestial objects. This section covers a few observing tips to help improve the
viewing experience.
PLEASE DO NOT LOOK AT THE SUN WITHOUT PROPER SOLAR FILTER.
14
AZ60 TELESCOPE
Moon Observing
The Moon is one of the most famous celestial object in
our solar system and it is the easiest to observe with a
telescope.
When looking through the telescope at the Moon, you
may find that the Moon is exceptionally bright when it
is at full moon. This is because the Moon is reflecting
the light from the Sun. Even though the Moon can be
very bright, the light it reflects is not harmful to your
eyes. It may take away your night version for a while,
but it will not pose any damage to your eyes.
When observing the Moon’s surface details, it is better
to install the optional Moon filter. The Moon filter is a
yellow-ish green filter to help bring the contrast of the
craters. If you are viewing through your phone with
the phone adapter, we recommend lowering the
exposure which will bring you a similar effect of having
a moon filter.
Planets Observing
Planets observing is also fascinating. However,
please note that Planets observing is limited by
the seeing condition of your observation site
including light pollution and atmospheric
condition. So observing planets in the city and/or
while the planets are low in the horizon may not
be the best options.
You may see the ring of Saturn; the lunar phase of
Venus; the Great Red spot of Jupiter; surface detail
of Mars, etc.

TELESCOPE BASICS
Telescope Maintenance
The main lens of the telescope is the most important part of the telescope, and all
Spectrum Optical Instruments telescopes have high transmission glass optics for
best performance. Each glass optic is fully coated, It is very important to protect
the coating and prevent any potential damages which can cause significant
decrease of performance. Here are a few maintenance tips you can perform to
ensure your telescope perform at its best for a long time.
•When the telescope is not in use, we recommend putting the dust cover back
onto the OTA to prevent any dust and/or moister build-up on the main optics.
•It is also recommended to cover the back of the OTA with the included plastic
plug to prevent foreign objects entering the OTA body and potentially causing
any damage to the inner coated surface of the OTA and more importantly, the
main optics.
•In case of dust/moisture build-up on the outside of the main optics, you can
remove it with a camel hair brush or pressurized air.
•When using a camel hair brush, make sure there is no foreign object
on the brush before using. Lightly move brush across the optic to
remove the dust/moisture;
•When using a can a pressurized air, spray the air onto the optics at an
angel so that the dust can be blown away from the optic.
•In case of moisture build-up occur on the inside of the OTA, remove the plastic
cover of the back of the OTA, and point the telescope downward to allow to
moisture to evaporate.
•In case of finger print/grease on the optics, it is necessary to remove it with the
correct cloth motion.
•Use any commercial optic cleaning solution with a optics cleaning
cloth/or white tissue with the least amount of debris;
•Apply the cleaning solution onto the cloth/tissue. DO NOT apply the
cleaning solution directly onto the optics;
•Apply the cloth/tissue to the optics with low pressure;
•Move the cloth/tissue from the center of the optics to the outer
portion. DO NOT RUB the optics!
•Repeat until optics is fully cleaned.
