Baader H-Beta 50.4mm Narrowband-Filter (5.5nm) – CMOS-optimized
Increased contrast. Ever more narrow 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 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.
