The Story

Highlights

2" x 2 mm Baader CMOS H-alpha / O-III / S-II Narrowband Filter Set – Precision Grade – with 2" (M48) filter thread
6.5 nm FWHM, recommended for optical systems from > f/3.4
Reflex-Blocker™ hard coated and Plane-optically polished – with sealed coating edges (Life-Coat™)
Blackened edges all around, with filter-lead-side-indicator in the form of a telescope-sided black outer rim
Optimized for modern CMOS cameras, but likewise excellent for CCD camera technologies
Mounted in Baader Low Profile Filter Cell (LPFC) – 6 mm height

Description

This new generation of Baader CMOS-filters features:

CMOS-optimized Baader Filters

Increased contrast

Ever more narrow band-passes

Reflex-Blocker^™ coatings, for largest ever freedom from halos, even under most

adverse conditions concerning aux-optics

FWHM on each filter category carefully designed to allow for 1:1:1 exposures, matched for typical CMOS quantum efficiency and s/n ratio

Identical filter thickness to existing standards, with utmost care for remaining Par focal

Blackened edges all around, with filter-lead-side-indicator in the form of a black front side outer rim, to additionally eliminate any reflection due to light falling onto the edge of a filter

Each filter coated individually, with sealed coating edge (NOT cut out of a larger plate with coatings left exposed, read more)

Life-Coat™: evermore hard coatings to enable a non-aging coating for life – even in a most adverse environment
