This new generation of Baader CMOS filters features:
Increased contrast
Increasingly narrower passbands
Reflex-Blocker ™ coatings, for the greatest freedom from halos, even in the most adverse conditions related to auxiliary optics
FWHM in each filter category carefully designed to allow 1: 1 exposures: 1, combined for typical CMOS quantum efficiency and s/n ratio
Filter thickness identical to existing standards, with extreme care for parafocality
Blackened edges all around, with filter lead side indicator in the form of a black outer edge on the front side, to additionally eliminate any reflections due to light falling on the edge of a filter
Each individually coated filter, with sealed coating edge (NOT cut from a larger plate with exposed coatings)
Life-Coat ™: increasingly harder coatings to enable a coating that will not age for life, even in the harshest environment
