Product Details

Baader H-alpha 6.5nm 2" Narrow band filter optimized for CMOS

This new generation of Baader CMOS filters features:

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/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 further 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, read more)
Life-Coat ™: increasingly hard coatings to enable a coating that will not age for life, even in the harshest environment

General features:

2" x 2 mm Baader H-alpha narrow band filter - Precision grade with M48 thread
6.5 nm FWHM, recommended for f / 10 af / 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
