Baader H-alpha 6.5nm 31mm filter optimized for CMOS
This new generation of Baader CMOS filters features:
- Increased contrast
- Ever narrower passbands
- Reflex-Blocker™ coatings, for largest ever freedom from halos, even under most adverse conditions concerning aux-optics
- FWHM on each filter category carefully designed to allow for 1:1:1 exposures, matched for typical CMOS quantum efficiency and s/n ratio
- Identical filter thickness to existing standards, with utmost care for parfocality
- 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 individually coated, with sealed coating edge (NOT cut out of a larger plate with coatings left exposed, read more)
- Life-Coat™: evermore hard coatings to enable a non-aging coating for life - even in a most adverse environment
General features:
- 31 mm x 2 mm Baader H-alpha narrow band filter - Accuracy grade
- 6.5 nm FWHM, recommended for f / 10 af / 3.5" optical systems
