eyepiece. Celestron offers two Barlow lens in the 1-1/4" size for the G-8. The

bly only and accessories) is constructed of space age resin, making it water-

Dew Cap/Lens Shade (#94017) -

diameter as the telescope) that fits on the front end of the telescope to reduce
the amount of dew that can build up on the corrector plate at night. The dew
cap also acts as a lens shade by preventing stray light from falling on the
corrector plate and into the tube possibly reducing contrast. The dew cap/lens
shade uses a bayonet mounting system for a snug fit.

Celestron’s 12 volt Dew Eliminator means viewing sessions can go longer. It
blows warm air to keep your corrector plate and any optional accessories dew-
free. Just plug it into your car’s cigarette lighter receptacle for trouble-free
observing. 156 watts. Weight: 9 ounces.
