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.
Reducer/Corrector (#94175) -
This lens reduces the focal length of the telescope by 37%, making your C8
a l280mm f/6.3 instrument. In addition, this unique lens also corrects inherent aberrations to produce crisp
images all the way across the field. It also increases the field of view significantly and is ideal for wide-
field, deep-sky viewing. It is perfect for beginning prime focus long-exposure astrophotography. It makes
guiding easier and exposures shorter.

Sky Maps (#93722)
- When learning the night sky, the Celestron Sky Maps offer the ideal solution. The
maps include all the constellations and brighter deep-sky objects. The maps are printed on a heavy stock
paper that is moisture-resistant. On the front cover is a rotating planisphere which indicates when specific
constellations are visible.
XX
Skylight Filter (#93621) -
The Skylight Filter is used on C8 telescopes as a dust seal. The filter threads
onto the rear cell of your telescope. All other accessories, both visual and photographic, thread onto the
Skylight Filter. Although it does cut down on a portion of the incoming light, it is a very small amount. It
should be noted, that most Barlow lenses can NOT be inserted into the visual back when the skylight filter
is attached.

Solar Filter (#94162)
- The Celestron Solar Skreen solar filter permits direct observation of the Sun in
complete safety. This filter, which transmits .001% of visible light, allows you to see sunspots as they move
across the solar disk. In addition to reducing the intensity of the Sun's visible light, it also blocks 99.999%
of invisible infrared light. The Celestron Solar Skreen solar filter is made of precision engineered Mylar
polyester film. A layer of aluminum is vacuum-deposited on one surface of the dual sheets of Mylar used to
make each filter. The aluminum coating produces a cool, comfortable pale blue image of the Sun. (A #21
orange eyepiece filter works well in conjunction with this filter to produce a more natural color Sun). This
filter can be used for visual observation and photography. This model is a full aperture filter.
XX
T-Adapter (#93633-A)
- A T-Adapter (with T-Ring) allows you to attach your camera to the prime focus of
a Celestron Schmidt-Cassegrain telescope. This is used for terrestrial photography and short exposure lunar
and filtered solar photography. It can be used for long exposure deep-sky photography if you use a separate
guidescope.
XX
T-Adapter/Barlow (#93640)
- A special T-Adapter with an integral 2x Barlow lens. The barlow is
removable so you can attach your camera to your Celestar and shoot at prime focus or 2x prime focus.
