Product Details

Highspeed Baader H-alpha 6.5nm 31 mm CMOS optimized 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 31 mm x 2 mm high-speed filters - Precision grade
FWHM of 6.5 nm, recommended for f/3.4 to f/1.8 optical systems
Specially designed for special filter requirements when used with fast optics such as astrographs Celestron RASA
Reflex-Blocker ™ hard-coated and planoptically polished, 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
