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.

Counterweight Bar Assemblies

The Counterweight Bar Assembly is a metal rod that runs the length of the telescope tube. It attaches to both the front and

rear cells. 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.

Counterweight Set: Ultima® 2000 – #94190

 

The standard set of weights works well when using

 

standard accessories, but when adding heavier

 

optional accessories, you’ll require this optional set of

 

weights to achieve proper balance. The set contains

#94190

one large and four small weights.

 

Lens Shades/Dew Caps

A Lens Shade/Dew Cap is a tube, of approximately the same diameter as your telescope tube, designed to fit on the front end of the telescope to reduce the amount of dew that builds up on the corrector plate. It

also serves as a Len Shade by preventing stray light #94017 from falling on the corrector plate, which greatly

improves contrast.

The C8 Lens Shades are made of rugged plastic, and

 

have a tapered design (other designs made with

 

different materials cause vignetting). They snap easily

 

onto the front cell of all of Celestron’s C8 telescopes.
