SET UP INSTRUCTION
Please DO NOT look at the Sun through your telescope without a proper filter. This may damage your eyes permanently.
Tripod & Mount
1. Release the tripod leg lock (6) and fully
extend the spread tripod legs (7) to set
the proper height
2. Place the tripod (3) on a relatively flat
ground where you have a clear view to
the sky (if you are viewing celestial
objects) or distanced ground (if you are
viewing land objects).
3. Adjust the height of the legs to level the
top of the tripod.
4. Attach the accessory tray (4) onto the
center spreader bars (5) and temporarily
place all the accessories there.
5. To install the slow motion control cables
(12) and (14), first loosen the slow
motion locking screws (13)and locate
the flat attachment area on the shaft.
6. Once the slow motion control cable is on
the shaft, tighten the locking screw to a
firm feel.
7. With these steps done properly, your
tripod and mount are now set up
correctly.
OTA
1. Locate the Vixen dovetail (23)and slide
the Optical Tube Assembly (OTA) (1)
onto the saddle plate (10)located on the
mount (2) and tighten the OTA lock knob
(9) to a firm feel.
2. Install the red dot view finder (15)and
secure it by tightening the lock knob (16)
to a firm feel.
3. Install the diagonal (18)into the optical
tube, and secure the diagonal by
tightening the diagonal lock knob (17).
4. Selectively install the Barlow Lens per
desire
5. Slide an eyepiece (20)into the diagonal
and secure it by tightening the eyepiece
locking screw (19).
View Finder Alignment
1. Point the OTA at a distanced land object during
the daytime, such as a distanced light pole.
2. Look through the lower-power eyepiece first
and center the object in the eyepiece
3. Focus the telescope by turning the focus knob
(24a) of (24b) till the object is sharp and clear.
4. Turn on the red dot viewfinder by turning the
view finder on-off switch (22)and look through
it. Adjust the red dot by turning one of the two
view finder alignment knobs (21)till the red
dot is overlapping the same object centered in
the eyepiece.
5. Repeating the same process at night by
pointing at a celestial object such as the Moon
will further align your viewfinder and OTA.

FAQs
What is aperture of a telescope?
Aperture of a telescope refers to the diameter of the diameter of the objective lens (for refracting telescope) or the primary mirror (for reflecting
telescopes). The aperture of the telescope determines how light the telescope and observe hence how much detail you can see. The rule of
thumb: the bigger the aperture, the more detail you can see.
Should I choose the larger aperture?
Aperture of a telescope is what determines how much light can a telescope observe. The larger the aperture, the more light can be collected,
which results in greater image resolution. In short, with a telescope with a larger aperture, you can see more detail and better detail than the one
with a smaller aperture. However, the larger the aperture, the more expensive the telescope is.
How to calculate the magnification of a telescope?
The magnification of a telescope is equal to the telescope’s focal length divided by the eyepiece’s focal length. Focal length of a telescope and an
eyepiece can be found on the specification sheet, on our telescope, the two are actually printed onto the body of the OTA and the eyepieces for
easier access. For example, with a 20mm eyepiece, a 900mm OTA will give you 45X magnification; with a 10mm eyepiece, a 900mm OTA will give
you 90X magnification.
What does the number on an eyepiece mean?
The number on an eyepiece refers to the focal length of the eyepiece which is usually measured in millimeter (MM). For example, a 25mm
eyepiece has a focal distance of 25mm. The bigger the number, the longer the focal which results in a lower magnification.
Please DO NOT look at the Sun through your telescope without a proper filter. This may damage your eyes permanently.

How to take an image through a telescope with a phone?
Our telescopes are perfect for taking image of bright objects such as the moon. To take an image through a telescope with your phone is very
easy. Point the telescope at and focus on the object you want to take an image of, then use our included bonus smartphone holder to hold your
phone with, then simply take a picture.
Better yet, you can use our included Bluetooth shutter to control your phone to avoid any potential shaking induced by touching the screen of
your phone directly. You can of course simply hold your phone next to the eyepiece and take a picture.
Why is my OTA pointing at one object and my view finder is pointing at another?
In this case, there is ahigh possibility that your OTA is not properly aligned with the viewfinder.
We recommend aligning the two in the morning first. Point your telescope at a land object that is at a far distance, such as a street light or a
“STOP” sign, and center the object in the eyepiece. Adjust view finder alignment screws till the viewfinder is pointing at the same object you
have centered in your eyepiece.
Then, repeat the same procedure at night by pointing at a large ad bright celestial object such as the moon. Small adjustments may be required
at this point.
After these two steps. Your OTA and view finder are aligned properly.
Please DO NOT look at the Sun through your telescope without a proper filter. This may damage your eyes permanently.

FAQs
What can be observed by my telescope?
With the included eyepieces, you can observe the crater of the moon, planets of our solar system (Saturn), as well as Orion Nebula. You can also
observe terrestrial objects such as sail boat. However, please keep in mind that never look at the Sun without a proper solar filter, this may
permanently damage your eyes.
There are 3 included eyepieces, which one should I start with?
Best practice is to start with lower power eyepiece because the lower magnification gives you a large Field of View (FOV) of the sky making
locating the object easier. After centering the object in the eyepiece, you may switch to a higher power eyepiece to see more detail.
Will this telescope work with my 1.25’’ eyepieces?
Yes, by default, this telescope has a 1.25’’ eyepiece adapter so it will work with all the 1.25’’ accessories.
What is a Barlow lens?
A Barlow in astronomy is a lens to increase the magnification of a telescope. Usually, a Barlow would be labelled “2X,” “3X,” and etc. a 2X Barlow
doubles the magnification of your telescope and a 3X Barlow trebles the magnification. For example, using a 2X Barlow on a setup that originally
give you 150X magnification will double your magnification making the overall magnification 300X
