Product Details

Baader H-alpha 6.5nm 50.4 mm CMOS optimized Narrowband Baader H-alpha Filters

This new generation of Baader CMOS filters features:

CMOS-optimized Baader filters
Increased contrast
Increasingly narrower pass bands
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: 1: 1 exposures, combined for typical CMOS quantum efficiency and s/w 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 filter individually coated, with sealed coating edge (NOT cut from a larger plate with exposed coatings)
Life-Coat ™: increasingly harder coatings to allow for a coating that will not age for life, even in the harshest environment

Summary key features:

Baader H-alpha 50.4 mm x 3 mm narrow band filters - Precision grade
FWHM of 6.5 nm, recommended for f/10 to f/3.5 optical systems
Hard-coated and planoptically polished Reflex-Blocker™ with sealed coating edges (Life-Coat™)
Blackened edges all around, with filter lead-side indicator in the form of a black outer edge on the front side
Optimized for modern CMOS cameras, but excellent for CCD camera technologies
