Alpine Astronomical Baader Clearglass Filter 2 Unmounted for FCCT (CMOS Optimized)
This Baader Clearglass Filter 2 Unmounted for FCCT (CMOS-Optimized) from Alpine Astronomical is used to focus a camera when using very narrow band line filters (due to same mechanical thickness) with no halos, reflection, or ghosting. It is also used for dust protection.

- Optimized for modern CMOS cameras, but likewise excellent for older CCD camera technologies
- Anti-reflection RGB filter (red/green/blue) with extremely high transmission of the respective color channel, thus simultaneously reducing stray light and reflections to an unprecedented level
- Balanced RGB design allows subframes to be taken with the same exposure time - extremely important for automated imaging tasks
- Increased contrast
- Reflex-Blocker coatings
- FWHM on each filter category carefully designed to allow for 1:1:1 exposures, matched for typical CMOS quantum efficiency and s/n ratio
- Blackened edges all around, with filter-lead-side-indicator in the form of a black frontside outer rim, to additionally eliminate any reflection due to light falling onto the edge of a filter with filter-lead-side-indicator in the form of a telescope-sided black outer rim
- Each filter coated individually, with sealed coating edge, not cut out of a larger plate with coatings left exposed
- Reflex-Blocker hard coated and planeoptically polished, with sealed coating edges (Life-Coat)
