Baader 6.5nm Narrowband-Filter-Set 2" – CMOS-optimized (H-alpha / O-III / S-II)

This new generation of Baader CMOS-filters features:

  • Increased contrast
  • Ever more narrow passbands
  • 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 parfocality
  • Blackened edges all around, with filter-lead-side-indicator in the form of a black frontside 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)
  • Life-Coat™: evermore hard coatings to enable a non-aging coating for life – even in a most adverse environment
  • Optimized for modern CMOS cameras, but likewise excellent for CCD camera technologies
  • Mounted in Baader Low Profile Filter Cell (LPFC) – 6 mm height
