Questar Filter Sets

Questar eyepiece color filters thread into the chrome barrels of Questar Brandon eyepieces only. They are available in a pre-selected ten-filter set. Each 1” clear aperture filter in the set uses polished plane-parallel optical glass to minimize internal reflections and ghosting. Each is antireflection coated and mounted in matte black low reflectivity cell with a thin knurled grip ring for a more secure hold in cold weather. The filter number is engraved into the side of each filter to eliminate guessing about which color you're looking at when examining a filter at night with a red flashlight.
