BAADER LRGB CMOS-OPTIMIZED FILTERS
Baader Planetarium
BAADER LRGB CMOS-OPTIMIZED FILTERS - 1¼" is backordered and will ship as soon as it is back in stock.
The new Baader CMOS-optimized LRGB filters are designed to work very well with modern highly-sensitive astronomy cameras and telescopes with focal ratios between f/15 to f/1.8. With excellent halo and reflection control, these filters set the new standard for monochrome astrophotography with CMOS sensors.
Baader's RGB filters have high transmission and are balanced across each colour channel, so you don't have to calculate individual exposure times for each filter. The Luminance UV/IR blocking filter has 98% transmission over the entire visible spectrum.
Baader LRGB 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 front-side markings
- 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
