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
