PowerTank (#18774)
–
12v 7Amp hour rechargeable power supply. Comes with two 12v output cigarette
outlets, built-in red flash light , Halogen emergency spotlight. 120v AC adapter and cigarette lighter adapter
included. Celestron also offers a 17 amp hour models (#18777).
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.
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 CPC 11 a 1764mm f/6.3 instrument and
the CPC 800 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 Map
s
(#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.
E
ven 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
CPC
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 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. Celestron offers filters for CPC 800 (#94162).
T-Adapter (#93633-A) - T-Adapter (with additional T-Ring) allows you to attach your SLR camera to the rear cell of your Celestron CPC.
This turns your CPC 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.
Tele-Extender, Deluxe (#93643) - The tele-extender is a hollow tube that allows you to attach a camera to the telescope when the eyepiece is
installed. This accessory is used for eyepiece projection photography which allows you to capture very high power views of the Sun, Moon, and
planets on film. The tele-extender fits over the eyepiece onto the visual back. This tele-extender works with eyepieces that have large housings,
like the Celestron Ultima series.
Wedge, Heavy Duty (#93655) – The wedge allows you to tilt the telescope so that its polar axis is parallel to the earth's axis of rotation. Ideal
for using your CPC for guided astrophotography.
