Baader Narrowband 6.5nm 2" CMOS optimized filter set (H-alpha / O-III / S-II)

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/n 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 further 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, read more)
  • 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 / O-III / S-II narrow band filter set 2 "x 2 mm - Precision grade - with 2" (M48) filter thread
  • 6.5 nm FWHM, recommended for f/10 to f/3.5 optical systems
  • 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
  • Mounted on Baader Low Profile Filter Cell (LPFC) - 6 mm high
