You will find that additional accessories enhance your viewing pleasure and expand the usefulness of your telescope. For 
ease of reference, all the accessories are listed in alphabetical order. 
 
Adapter, Car Battery (#18769) -  

Celestron offers the Car Battery Adapter that allows you to run the NexStar drive off 

an external power source.  The adapter attaches to the cigarette lighter of your car, truck, van, or motorcycle. 
 

 Barlow lens, OMNI 1.25"  (#93326) -  Double the magnification of any of your 
Celestron eyepieces with this fully multi-coated, low profile Barlow lens  
 
Carrying Case, Soft NexStar 60/80/102 (#302160) - Lightweight yet durable, 
this nylon case is ideal for transporting your NexStar telescope. The shoulder and 
back straps provide hands-free convenience to make carrying your telescope 
anywhere even easier. 
 

Erect Image Diagonal (#94112-A) -  This accessory is an Amici prism arrangement that allows you to look into the 
telescope at a 45° angle with images that are oriented properly (upright and correct from left-to-right).  It is useful for 
daytime, terrestrial viewing with the NexStar 60, 80 and 102 

 

Eyepieces -  Like telescopes, eyepieces come in a variety of designs.  Each design has its own advantages and 
disadvantages.  For the 1-1/4" barrel diameter there are four different eyepiece designs available: 
 

• 

  -  Plössl eyepieces have a 4-element lens designed for low-to-high power 

observing.  The Plössls offer razor sharp views across the entire field, even at the edges!  In 
the 1-1/4" barrel diameter, they are available in the following focal lengths:  4mm, 6mm, 
9mm, 12.5mm, 15mm, 20mm, 25mm, 32mm and 40mm

. 

 

• 

X-Cel - This 6 element design allows each X-Cel Eyepiece to have 20mm of eye relief, 55° 
field of view and more than 25mm of lens aperture (even with the 2.3mm). In order to 
maintain razor sharp, color corrected images across its 50° field of view, extra-low 
dispersion glass is used for the most highly curved optical elements. The excellent 
refractive properties of these high grade optical elements, make the X-Cel line especially 
well suited for high magnification planetary viewing where sharp, color-free views  are 
most appreciated.  X-Cel eyepiece come in the following focal length: 2.3mm, 5mm, 8mm, 
10mm, 12.5mm, 18mm, 21mm, 25mm.

 

 

• 

Ultima -  Ultima is not really a design, but a trade name for our 5-element, wide field 
eyepieces.  In the 1-1/4" barrel diameter, they are available in the following focal length:  5mm, 7.5mm, 10mm 12.5mm, 
18mm,  30mm, 35mm, and 42mm.  These eyepieces are all parfocal. 

 

 
The Eyepiece and Filter Kit (#94303) – contains Five Superior Grade Plössl Eyepieces - 
1.25”. Barlow Lens - 2x 1.25”. Six Colored Eyepiece (Lunar & Planetary) Filters. Moon 
Filter. Aluminum Carrying Case 
 
Flashlight , Night Vision - (#93588) - Celestron’s premium model for astronomy, using two 
red LEDs to preserve night vision better than red filters or other devices.  Brightness is 
adjustable.  Operates on a single 9 volt battery (included).   
 
Filter,  Light Pollution Reduction –UHC/LPR (#94123) - These filters are designed to 
enhance your views of deep sky astronomical objects when viewed from 
urban areas.  LPR Filters selectively reduce the transmission of certain 

wavelength of light, specifically those produced by artificial lights.  This includes mercury and high 
and low pressure sodium vapor lights.  In addition, they also block unwanted natural light (sky glow) 
caused by neutral oxygen emission in our atmosphere.
