Product Details

Baader H-Beta 5.5nm 31 mm CMOS optimized Narrowband Baader H-Beta Filters

This new generation of Baader CMOS filters features:

CMOS-optimized Baader filters
Increased contrast
Narrower and 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:

31 mm x 2 mm Baader H-Beta narrow band filters - Precision grade
FWHM of 5.5 nm, recommended for f/10 to f/3.5 optical systems
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

The Baader digital solar filter with PHOTO-Film OD 3.8 has proven its effectiveness for many years, furthermore it allows shorter exposure times, mainly used for digital videography and lucky imaging technique, and thus almost "freezes" turbulences in the earth's atmosphere. It is NOT designed for observing the sun, only for digital imaging!
