How To Set Up
Assembly:
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. Put the accessory tray in place and turn
it clockwise until stable. To set the tripod height, turn the pressure fitting on each leg counterclockwise
until loose. Extend or retract the leg to the desired setting, then tighten the pressure fitting until snug.
2. Thread the panhandle clockwise onto the tripod head.
3. Set the optical tube assembly on the tripod head and align the tab on the bottom of the telescope tube
with the slot in the tripod head. Thread the front tension wheel until snug, then tighten the side tension
thumbscrew. Be careful not to over-tighten either thumbscrew.
4. Insert the diagonal into the focuser and secure it by tightening the thumbscrews.
5. To install the bracket for the red dot viewfinder, remove the two metal thumbscrews on the top of the
telescope tube. Place the bracket in position over the holes, replace the thumbscrews and tighten until
secure. Be careful not to over-tighten either thumbscrew.
6. After installing the bracket, slide the red dot viewfinder into the bracket and secure it by tightening
the three screws around the ring.
7. Place your chosen eyepiece into the diagonal. We recommend starting with the 20mm because it will
provide the widest field of view.
Telescope Terms To Know:
Diagonal: 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 diagonal mirror appears upright, but rotated around its
vertical axis (mirror image).
Focal length: Everything that magnifies an object via an optic lens has a certain focal length. The focal
length is the length of the path the light travels from the surface of the lens to its focal point. The focal
point is also referred to as the focus. In focus, the image is clear. In the case of a telescope, the focal
length of the telescope tube and the eyepieces are used to determine magnification.
Lens: The lens turns the light that falls on it around in such a way so that the light gives a clear image in
the focal point after it has traveled a certain distance (focal length).
Eyepiece: An eyepiece is a system made for your eye and comprised of one or more lenses. In an
eyepiece, the clear image that is generated in the focal point of a lens is captured and magnified still
more.
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.
NOTE:
The magnifying power of a telescope is determined by dividing the focal length of the telescope by
the focal length of the eyepiece. This means that as the focal length of your eyepiece increases, the
magnifying power decreases.

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.
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.
• Point the eyepiece at an easy to identify
target like a telephone pole that is
approximately 200 yards away. Center
the object in the eyepiece. Lock the
telescope into place by tightening the
panhandle.
• 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.
Note: To preserve battery life, don’t forget
to turn off the viewfinder after use.
Using Your Telescope:
After you have assembled your telescope, you are ready to start observing. Put the 20mm eyepiece
into the diagonal to get the widest field of view. This wider field of view will make it easier to locate
and track objects.
To move the scope up, down and side to side, loosen the locking screws slightly and grip the telescope
near where the tube meets the focuser and steadily move the tube until your target comes into view in
the eyepiece. Once you have found and focused on your desired target, you can lock the telescope into
position by tightening the two locating screws.
It is important to remember that the rotation of the Earth means objects will move out of your
eyepiece fairly quickly.
For a closer look at an object, you can insert the K6 mm eyepiece. The magnification will increase
from 20x to 67x.
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 microfiber cloth. Do not press down too hard while cleaning, as this might
scratch the lens. Ask your parents to help if your telescope is really dirty. If necessary, the cleaning

cloth can be moistened with an optical glass cleaning fluid and the lens wiped clean using very little
pressure. Do not use harsh detergents!
Make sure your telescope is always protected against dust and dirt.
After use, leave it in a warm room to dry off before storing.
Possible Objects For Observation:
Terrestrial Objects
Take note of the examples below, including Mount Rushmore and the golf course. Start with
the K20 mm eyepiece and focus until the image is clear. After
mastering the K20 mm eyepiece, switch to the K6 mm eyepiece
and practice scanning and focusing until the image is clear. Choose
several terrestrial objects to practice focusing on, but never point
your telescope at or near the sun, or you risk blindness.
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 cloaked portions of the Moon meet.

Troubleshooting Guide:
Problem Solution
No picture Remove dust protection cap and sun-shield from the objective
opening.
Blurred picture Adjust focus using focus ring.
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 prism the
picture is “crooked”
The star diagonal prism should be vertical in the eyepiece
connection.

Using the Smartphone Adapter:
SUPERVISION BY ADULTS
Read and follow the instructions, safety rules and first aid information
The Smartphone Adapter will allow you to connect almost any “smart” device to a 1.25” eyepiece.
To use the adapter, place it directly onto the selected eyepiece and secure it by tightening the setscrew
until snug. Be careful not to overtighten because this could damage the adapter and/or the eyepiece.
The camera lens on your smart device will need to be centered over the eyepiece. This alignment is best
done by opening the camera function and viewing the image while you center the device. Once you have
positioned the device correctly, carefully press it onto the suction cup/non-skid surface of the adapter
pad. Never allow the adapter pad to hold your device without you supporting the item as well.
The point at which you secure the eyepiece/adapter combination into the diagonal depends largely on
the dimensions of your device. For smaller devices like smart phones, it may be easier to secure it to
the eyepiece/adapter combination before inserting the entire unit into the diagonal on the telescope.
For larger devices, such as tablets, it may be easier to secure the eyepiece/adapter combination into the
diagonal, and then align and attach your device.
After positioning your device and capturing images, you can enhance and edit the photos using the
imaging software of your choice. One option can be found at https://www.getpaint.net/.
WARNING: Do not leave your device unsupported or unattended on the adapter pad.
Though the surface of the adapter pad is designed with suction cups and is non-skid, the manufacturer
cannot assure that the pad will support the weight of various devices or guarantee that it will adhere to
all surfaces on various smart devices. The pad is not intended to secure, balance or support the device
on its own, and the operator should not let the device rest solely on the adapter pad. Leaving the device
unattended or allowing it to balance on its own without operator support may result in the device falling,
unbalancing the entire instrument and possibly damaging the telescope or your smart device.
