The Lumicon 90-Degree Enhanced Mirror Diagonal (2") w/ Built-In Filter Holder allows you to enjoy the combined convenience of a filter selector with the quality of an Enhanced Aluminum star diagonal, with both refractors and catadioptric telescopes. Its low-profile design allows you to achieve focus with all.
The typical use for this diagonal is to add a red/green/blue filter and use all 3 for a single exposure with a monochrome CCD camera, later combining the resulting images with software.
This version includes the Lumicon Enhanced optics for 96-97% reflectivity.
