Product Details

Ultra-Highspeed Baader H-alpha 3.5nm 50x50 mm CMOS optimized Ultra-Highspeed 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:

50x50 mm x 3 mm Baader H-alpha ultrafast speed filters - Accuracy grade
3.5 nm FWHM (to harmonize exposure time with O-III / S-II), recommended for extremely fast optical systems from f/3.4 to f/1.8
Specially designed for special filter requirements when used with fast optics such as the Celestron RASA astrographs
For the highest contrast even with the strongest light pollution, minimizes star size, emphasizes the finest details of the nebula, indispensable under Bortle 9/8/7 / (6) skies
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
