You will find that additional accessories for your PowerSeeker telescope will enhance your viewing 
pleasure and expand the usefulness of your telescope.  This is just a short listing of various accessories with 
a brief description.  Visit the Celestron website or the Celestron Accessory Catalog for complete 
descriptions and all accessories available.    
 

Sky Maps (# 93722) – 

Celestron Sky Maps are the ideal teaching guide for learning 

the night sky.  Even if you already know your way around the major constellations, 
these maps can help you locate all kinds of fascinating objects.  

 
 

Omni Plossl Eyepieces – 

These eyepieces are economically priced and offer razor sharp 

views across the entire field.  They are a 4-element lens design and have the following focal 
lengths: 4mm, 6mm, 9mm, 12.5mm, 15mm, 20mm, 25mm, 32mm, and 40mm – all in 1.25” 
barrels. 
 
 

Omni Barlow Lens (# 93326) – 

Used with any eyepiece, it doubles the magnification of that eyepiece.  A 

Barlow lens is a negative lens that increases the focal length of a telescope.  The 2x Omni is a 1.25” barrel, 
is under 3” (76mm) long, and weights only 4oz. (113gr.).  
 

Moon Filter (# 94119-A) – 

This is an economical 1.25” eyepiece filter for reducing the brightness of the 

moon and improving contrast, so greater detail can be observed on the lunar surface. 

 
 

UHC/LPR Filter 1.25” (# 94123) – 

This filter is designed to enhance your views of deep 

sky astronomical objects when viewed from urban areas.  It selectively reduces the 
transmission of certain wavelengths of light, specifically those produced by artificial lights.   
 
 

Flashlight, Night Vision (# 93588) – 

The Celestron flashlight uses two red LED’s to preserve night vision 

better than red filters or other devices.  Brightness is adjustable.  Operates on a single 9-volt included 
battery. 
 

Collimation Tool (# 94183) – 

Collimating your Newtonian telescope is easily accomplished with this 

handy accessory which includes detailed instructions. 
 

Collimation Eyepiece – 1.25” (# 94182) – 

The collimation eyepiece is ideal for precise collimation of 

Newtonian telescopes. 
   

Digital Camera Adapter – Universal (# 93626) – 

A universal mounting platform that 

allows you to do afocal photography (photography through the eyepiece of a telescope) using 
1.25” eyepieces with your digital camera. 
 
 

T-Adapter – Universal 1.25” (# 93625) – 

This adapter fits the 1.25” focuser of your telescope.  It allows 

you to attach your 35mm SLR camera for terrestrial as well as lunar and planetary photography. 
 

Motor Drive (# 93514) – 

A single axis (R.A.) motor drive for the PowerSeeker telescopes compensates for 

the earth’s rotation keeping an object in the eyepiece field of view.  This makes observing much more 
enjoyable and eliminates the constant use of the manual slow motion controls.
