Baader H-alpha 31 mm f/3 (3.5 nm) Ultra High Speed Baader H-alpha Filter - CMOS optimized

  • Baader H-alpha f/3 31 mm x 2 mm H-alpha CMOS ultra high-speed filter - Premium grade
  • 3.5 nm FWHM (to harmonize exposure time with O-III/S-II), recommended for fast f/3.4 to f/2.3 optical systems
  • Specially designed for special filter requirements when used with fast f/3 optics
  • For higher 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
  • Hard-coated, plano-optically polished Reflex-Blocker™ with sealed coating edges ( Life-Coat™ )
  • Blackened edges all around, with lead filter side indicator in the form of a black outer edge on the telescope side
  • Optimized for modern CMOS cameras, but equally excellent for CCD camera technologies
