Highspeed Baader H-alpha 6.5nm 31 mm CMOS optimized filters

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/w 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 additionally 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)
  • Life-Coat ™: increasingly harder coatings to allow for a coating that will not age for life, even in the harshest environment
Summary key features:
  • Baader H-alpha 31 mm x 2 mm high-speed filters - Precision grade
  • FWHM of 6.5 nm, recommended for f/3.4 to f/1.8 optical systems
  • Specially designed for special filter requirements when used with fast optics such as astrographs Celestron RASA
  • 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
