Baader OIII Ultra Narrowband 4nm 36mm filter optimized for CMOS

This new generation of Baader CMOS filters features:

  • CMOS optimized Baader filters
  • Increased contrast
  • Narrower and 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 hard coatings to allow for a coating that will not age for life, even in the harshest environment

General features:

  • 36 mm x 2 mm Baader O-III ultra narrow band filter - Superior grade
  • 4 nm FWHM, recommended for f / 10 af / 3.5 optical systems
  • For the highest contrast even with the strongest light pollution, minimizes star size, emphasizes the finest details of the nebula, indispensable under Bortle 9/8/7 / (6) skies
  • 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
