Product Details

Baader Narrowband 6.5nm 1¼" CMOS optimized filter set (H-alpha / O-III / S-II)

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/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 allow for a coating that will not age for life, even in the harshest environment

Summary key features:

Baader H-alpha / O-III / S-II 1¼" x 2 mm narrow band filter set - Precision grade - with 1¼" (28.5 mm) filter thread
6.5 nm FWHM, 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
Mounted on Baader Low Profile Filter Cell (LPFC) - 6 mm high
