Baader f/2 Highspeed-Filter CMOS-optimized

  • Baader H-alpha / O-III / S-II f/2 Highspeed Filter Set – Precision Grade
  • 6.5 nm FWHM, recommended for extremely fast optical systems from f/3.4 to f/1.8
  • Specially designed for the special filter requirements when used with fast optics like the Celestron RASA astrographs
  • 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 black frontside outer rim
  • Optimized for modern CMOS cameras, but excellent for CCD camera technologies

This new generation of Baader CMOS-filters features:

CMOS-optimized Baader Filters

  • Increased contrast
  • Evermore 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 is coated individually, with a 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
