Celestron Filters

Celestron filters improve contrast on specific targets for visual observing and imaging. For the Moon there are a 1.25" Moon filter, a neutral density Moon filter, a Moon filter set and a variable polarizing filter that dims the glare to taste.

For deep-sky objects, the UHC/LPR filter (1.25" and 2") reduces light pollution and the Oxygen III narrowband filter brings out planetary and emission nebulae. RASA 8 and RASA 11 owners will find dedicated light pollution imaging filters, plus a lunar and planetary color set.
