IMAGING ACCESSORIES

RADIAL GUIDER

Specifically for use in prime focus, deep-sky imaging or astrophotography

with Schmidt-Cassegrain telescopes. This accessory allows you to simultane-

ously 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 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.

Model #94186 11 lb. counterweight for use with CG-5 mounts

Model #91525-2 25 lb. counterweight for use with CGE mounts

COUNTERWEIGHT BAR ASSEMBLY

The Counterweight Bar Assembly is a metal rail that runs the

length of the telescope tube. It attaches to both the front and

rear cells of Schmidt-Cassegrain telescopes.

Once the Bar Assembly is in place, counterweights

can be attached to it and moved along its length,

as well as perpendicular to it, for better dynamic

balancing. Each Counterweight Bar Assembly comes

with mounting hardware and one 2.5 lb. weight.
