PHOTO ACCESSORIES

Reducer/Corrector f/6.3 – #94175

This combination focal reducer and field corrector lens accessory works with all Celestron C5, C8, C91/4 , C11 and C14 telescopes. This clever accessory makes it possible to have a dual focal ratio instrument, without sacrificing image quality. The Reducer/Corrector is f/6.3 for C5, C8, C91/4 and C11 telescopes and f/7 for the C14 telescope.

If offers wide fields of view with any Schmidt-

Cassegrain telescope. Used for astrophotography, it reduces exposure time by a factor of 3.

Celestron doesn’t offer a f/6.3 Schmidt-Cassegrain telescope, because the design is impractical, with a large central obstruction, and resulting loss in contrast. This, added to the inability to utilize longer focal ratios for certain objects, led Celestron to design the four-element, fully multicoated f/6.3 Reducer/Corrector. Results are amazing both visually and photographically.

Radial Guider – #94176

Specifically for use in prime focus, deep-sky imaging or astrophotography with Schmidt-Cassegrain telescopes, the Radial Guider is compact and sleek in design. This accessory makes it possible to simulta-

neously photograph and guide through the optical tube assembly of your telescope. The Radial Guider also eliminates the problem of differential flexure, because you’re both guiding and photographing through the telescope.

The Radial Guider is compatible with Celestron’s C5, C8, C91/4, C11 and C14 telescopes and comes with a unique prism angle adjustment screw. It must be used with a guiding eyepiece, camera T- Ring and drive corrector (dual axis preferred).

Primarily for use with catadioptric telescopes, but also works on refractor telescopes having adequate back focus.

This guider is a tremendous improvement over conventional off-axis guiders. Not only is the angle of the prism tunable, but it also maintains a fixed rigid camera orientation while still offering users the freedom to move the guiding eyepiece radially about 135°.
