| Meade individual glass eyepiece color filters thread into the chrome barrels of virtually all 1.25" eyepieces available today (except Vernonscope and Questar Brandons, which require Questar/Vernonscope brand filters). The filters are available separately to allow you to build a filter collection matched to your observing needs. They are also available in several pre-selected four-filter sets at a lower cost than the total of the filters bought individually. Each 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 printed on 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. Each filter has dual threads to allow you to stack two filters together – to combine a neutral density filter with a color filter to simultaneously reduce glare and enhance contrast, for example. Each 26mm clear aperture filter is packed in a foam-lined plastic storage case. Those who have more than one filter might find optional filter case FP4 useful to keep all the filters in one convenient container.
