Celestron CPC Heavy Duty Wedge for fork mounted SC Telescopes

Celestron CPC wedge for all fork-mounted Celestron Schmidt Cassegrain telescopes

Allows long time exposures through equatorial setup.

The Celestron CPC wedge allows equatorial operation with all fork-mounted Celestron Schmidt Cassegrain telescopes These telescopes come with an altazimuth GoTo mount. The wedge is installed between the tripod and the telescope. No additional parts are required.

The advantages of the CPC wedge

improved stable design

adjustment range from 0° to 90° - usable at any place on earth

with micro-adjustment for precise setting of latitude and azimuth

The wedge is ready for use with the following Celestron telescopes:

All CPC telescopes

NexStar 6SE and NexStar 8SE

Also all predecessors of the Celestron CPC telescopes

When is the wedge useful?

The field of application of a wedge is astrophotography with long exposure times. From about 30 seconds exposure time on, the image field rotation starts to become visible with an altazimuth GoTo mount. All stars appear to rotate around the center of the image.
This effect occurs because the tracking is accomplished by moving both motors, the horizontal and the vertical. The wedge turns the azimuthal motor into the motor of the hour axis or right ascension axis and thus the azimuthal mount into an equatorial fork mount.
