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

film. It also increases the field of view significantly and is ideal for wide-field, deep-space viewing.

It is also perfect for beginning prime focus, long-exposure astro photography when used with the

radial guider. It makes guiding easier and exposures much shorter.

Sky Maps (#93722) - Celestron Sky Maps are the ideal teaching guide for learning the night sky.

You wouldn’t set off on a road trip without a road map, and you don’t need to try to navigate the night sky without a map

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

fascinating objects.

Skylight Filter (#93621) - The Skylight Filter is used on the Celestron telescope as a dust seal. The filter threads onto the

rear cell of your telescope. All other accessories, both visual and photographic (with the exception of Barlow lenses), thread

onto the skylight filter. The light loss caused by this filter is minimal

Solar Filter - The Baader AstroSolar® filter is a safe and durable filter that covers the front opening of the telescope. View

sunspots and other solar features using this double-sided metal coated filter for uniform density and good color balance across

the entire field. The Sun offers constant changes and will keep your observing interesting and fun. C8 - #94128, C9.25 -

#94237, C11 - #94238.

T-Adapter (#93633-A) - T-Adapter (with additional T-Ring) allows you to attach your SLR camera to the rear cell of your

Celestron telescope. This turns your telescope into a high power telephoto lens perfect for terrestrial photography and short

exposure lunar and filtered solar photography.

T-Ring - The T-Ring couples your 35mm SLR camera body to the T-Adapter, radial guider, or tele-extender. This accessory

is mandatory if you want to do photography through the telescope. Each camera make (i.e., Minolta, Nikon, Pentax, etc.) has

its own unique mount and therefore, its own T-Ring. Celestron has 8 different models for 35mm cameras.
