This new generation of Baader CMOS-filters features:

CMOS-optimized Baader Filters

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, read more)

Life-Coat™: evermore hard coatings to enable a non-aging coating for life – even in a most adverse environment
2" x 2 mm Baader S-II f/2 Highspeed Filter – Precision Grade – with 2" (M48) filter thread
6.5 nm FWHM, recommended for extremely fast optical systems from f/3.4 to f/1.8
Specially designed for the special filter requirements when used with fast optics like the Celestron RASA astrographs
Reflex-Blocker™ hard coated and planeoptically polished – with sealed coating edges (Life-Coat™)
Blackened edges all around, with filter-lead-side-indicator in the form of a black frontside outer rim
Optimized for modern CMOS cameras, but excellent for CCD camera technologies
