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.

• 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.

• Thread the panhandle clockwise onto the tripod head. 

• 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 screw.  

• Insert the diagonal into the focuser and secure it by tightening the thumbscrews. 

• Slide the red dot viewfinder into the finder bracket that is already mounted on the telescope tube. 

• Place your chosen eyepiece into the diagonal. We recommend starting with the 20mm because it will 

provide the widest field of view. 

Using Your Telescope:

Put the 26mm 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 26mm eyepiece and replace it with 
the 9.7mm eyepiece. This will increase the 
magnification from 23x to 61.8x. For the 
strongest magnification, take out the 9.7mm 
eyepiece and insert the 2x Barlow lens into the focuser. Put the 9.7mm eyepiece into the Barlow lens and 
secure it in place, this will up the magnification from 61.8x to 123x. If you use the Barlow lens with the 26 
mm eyepiece, the magnification will change from 23x to 46x.

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 microfiber 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.
