Radial Guider. Celestron 93664

IMAGING ACCESSORIES

RADIAL GUIDER

Specifically for use in prime focus, deep-sky imaging or astrophotography with Schmidt-Cassegrain telescopes. This accessory allows you to simultaneously photograph and guide through the optical tube assembly of your telescope. It also eliminates the problem of differential flexure, because you are guiding and photographing through the telescope.

Compatible with Celestron’s C5, C6, C8, C9.25, C11 and C14 telescopes the radial guider features 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.

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°.

EXTRA COUNTERWEIGHTS

Using accessories such as cameras,

Lens Shades, Tele-

Extenders and the 2” Diagonal #94186 #94203 #94189 #94187 will affect the balance of your Celestron Schmidt-Cassegrain telescope. Counterweights restore proper balance, increasing ease in handling and improved tracking accuracy.

You don’t need perfect balance to operate your telescope. In fact, it’s not always possible to achieve perfect balance with fixed-position weights. All you need to do is reduce, or eliminate, swing when R.A. and DEC locks are released. Celestron counterweights help you achieve the desired balance and stability with ease.
