This Baader CMOS‘ Optimized RGB Bandpass Filterset, from Alpine Astronomical, includes all three RGB filters.
Alpine Astronomical Baader CMOS-Optimized RGB-R Bandpass Filter (50.4mm Round, Unmounted)
This 50.4mm Round, Unmounted Baader CMOS-Optimized RGB-R Bandpass Filter , from Alpine Astronomical is an anti-reflection RGB filter with extremely high transmission of the R color channel. Its balanced RGB design allows subframes to be taken with the same exposure time, making it ideal for automated imaging tasks. It features a Reflex-Blocker hard coating, which has been planeoptically polished, and has Life-Coat sealed coating edges. It is equally suitable for modern CMOS sensors as well as for older CCD camera technologies.
- Reflex-Blocker coatings offer largest ever freedom from halos, even under most adverse conditions concerning aux-optics
- Provides increased contrast
- Identical filter thickness to existing standards (2mm), with utmost care for parfocality
- 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
- Each filter coated individually, with sealed coating edge (not cut out of a larger plate with coatings left exposed)
- Life-Coat: evermore hard coatings to enable a non-aging coating for life - even in a most adverse environment
Alpine Astronomical Baader CMOS-Optimized RGB-G Bandpass Filter (50.4mm Round, Unmounted)
This 50.4mm Round, Unmounted Baader CMOS-Optimized RGB-G Bandpass Filter , from Alpine Astronomical is an anti-reflection RGB filter with extremely high transmission of the G color channel. Its balanced RGB design allows subframes to be taken with the same exposure time, making it ideal for automated imaging tasks. It features a Reflex-Blocker hard coating, which has been planeoptically polished, and has Life-Coat sealed coating edges. It is equally suitable for modern CMOS sensors as well as for older CCD camera technologies.
