Flashlight, Night Vision - (#93588) - Celestron’s premium model for astronomy, using two red LED's to preserve night

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

CN16 GPS Accessory (#93968) - Plug in this 16-channel GPS module into your telescopes drive base port to link up and

automatically download information from one of many global positioning satellites. Controlled with the computerized hand

control, the CN-16 will greatly improve the accuracy of your star alignments.

Light Pollution Reduction (LPR) Filters - 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 wavelengths 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. Celestron

offers a model for 1-1/4" eyepieces (#94123) and a 2" eyepieces (#94124).

Micro Guide Eyepiece (#94171) - This multipurpose 12.5mm illuminated reticle can be used for

guiding deep-sky astrophotos, measuring position angles, angular separations, and more. The laser

etched reticle provides razor sharp lines and the variable brightness illuminator is completely

cordless. The micro guide eyepiece produces 163 power with the C8 and 188 power with the C9.25.

Polarizing Filter Set (#93608) - The polarizing filter set limits the transmission of light to a

specific plane, thus increasing contrast between various objects. This is used primarily for terrestrial,

lunar and planetary observing.

PowerTank (#18777) – For your heavy duty power requirements try this 12v 17Amp hour rechargeable power supply.

Comes with two 12v output cigarette outlets, built-in red flash light and raido , Halogen emergency spotlight. Switchable

110v/220v AC adapter and cigarette lighter adapter included.

Radial Guider (#94176) - The Celestron Radial Guider

is specifically designed for use in prime focus, deep sky

astrophotography and takes the place of the T-Adapter. This device allows you to photograph and guide simultaneously

through the optical tube assembly of your telescope. This type of guiding produces the best results since what you see

through the guiding eyepiece is exactly reproduced on the processed film. The Radial Guider is a “T”-shaped assembly that

attaches to the rear cell of the telescope. As light from the telescope enters the guider, most passes straight through to the

camera. A small portion, however, is diverted by a prism at an adjustable angle up to the guiding eyepiece. This guider has

two features not found on other off-axis guiders; first, the prism and eyepiece housing rotate independently of the camera

orientation making the acquisition of a guide star quite easy. Second, the prism angle is tunable

allowing you to look at guide stars on-axis. This accessory works especially well with the

Reducer/Corrector.

Reducer/Corrector (#94175) - This lens reduces the focal length of the telescope by 37%,

making your C8-S a 1280mm f/6.3 instrument. In addition, this unique lens also corrects inherent

aberrations to produce crisp images all the way across the field when used visually. When used

photographically, there is some vignetting that produces a 26mm circular image on the processed
