BAADER CMOS-OPTIMIZED FILTERS

About

Baader's CMOS-optimized filters have excellent halo and reflection control , increased contrast and even more narrow passbands than previous generations. These filters set the new standard for monochrome astrophotography with CMOS sensors . Baader's Highspeed f/2 & f/3 filters are designed for use with fast optics such as the Celestron RASA and Sharpstar Hyperbolic Newtonians . Baader CMOS-optimized filters - advantages Very high contrast due to steep edges of the coating Reflex-Blocker coatings to minimize reflections caused by correctors, reducers and other optical elements Standardized thickness for maximum possible parfocality - less need to refocus due to different filter thicknesses Blackened edges with side markings in the form of a black outer rim on the telescope side Each filter is individually fine-polished and coated with sealed coating edge, preventing moisture ingress Life-Coat for hardness and age-resistance, making the filters able to withstand tougher conditions for longer
