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. 

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 20mm 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 aligned your viewfinder, 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. 

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. 

For a closer look at an object, you can insert the 12.5mm eyepiece. 

The magnification will increase from 30x to 48x. 

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. f 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.  

 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 

sliding battery towards the front.  

Slide new battery in place with the 

positive (+) side showing.  Replace 

cap and tighten with 

set screw (Fig. 2).
