Opticstar 1.25" CRGbB Filter Set, 5 Filters

The Opticstar 1.25" CRGbB Filter Set (5 Filters) are positioned within a thin metal ring with a full 26mm clear aperture that threads into the barrel of any standard 1.25" eyepiece or filter wheel that can accept 1.25" filters. They help to increase contrast and reduce glare and light scattering. Each filter is threaded at both ends to accept another filter if required. Filters come inside individual plastic cases with a transparent window.
