Opticstar 1.25" High Transparency Filters for Imaging
These high transparency filters from Opticstar are placed 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.
Each of these high transparency filters is threaded at both ends to accept another filter if required. Filters come inside individual plastic cases with a transparent window.
All filters are IR blocked which is important when imaging.
