Baader H-alpha 65x65mm Ultra-Narrowband-Filter (3.5nm) – CMOS-optimized [BA-FCHALNU-SQ65]
$732.27 USDBaader: Baader H-alpha 65x65mm Ultra-Narrowband-Filter (3.5nm) – CMOS-optimized
- 65 x 65 mm x 3 mm Baader H-alpha Ultra-Narrowband Filter – Premium Grade
- 3.5 nm FWHM (to harmonize the exposure time with O-III / S-II), recommended for optical systems from f/10 to f/3.5
- For highest contrast even at strongest light pollution, minimizes star size, emphasizes finest nebula detail – indispensable under Bortle 9/8/7/(6) skies
- Reflex-Blocker™ hard coated and planeoptically 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

Baader 6.5nm Narrowband Filters – CMOS-optimized (H-alpha, O-III, S-11) [BA-FCSETN-SQ50]
$946.51 USDBaader has released the New CMOS-Optimized filters.
- Baader H-alpha / O-III / S-II Narrowband Filter Set - Precision Grade
- 6.5 nm FWHM, recommended for optical systems from f / 10 to f / 3.5
- 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 front side outer rim
- Optimized for modern CMOS cameras, but excellent for CCD camera technologies
The new generation of Baader CMOS-optimized filters features:
- CMOS-Optimized Baader Filter
- Increased contrast
- Ever more narrow pass bands
- 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 parfocalize
- 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
