Questar Individual Filters
· Show/Hide Description · (Product listings are below description)
Questar/Vernonscope individual eyepiece color filters thread into the chrome barrels of Vernonscope and Questar Brandon eyepieces only. Vernonscope filters are available separately to allow you to build a filter collection matched to your observing needs. Questar filters are available in a pre-selected ten-filter set and a variable polarizer. Each 1” clear aperture filter uses polished plane-parallel optical glass to minimize internal reflections and ghosting. They are antireflection coated and mounted in matte black low reflectivity cells with thin knurled grip rings 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.
