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.

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
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
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.
