Baader H-alpha 1¼" f/3 (3.5 nm) ultra high speed Baader H-alpha filter - CMOS optimized


  • Baader H-alpha f/3 1¼" x 2 mm ultra high speed CMOS premium grade 1¼" (28.5 mm) Baader H-alpha f/3 ultra high speed filter - with 1¼" (28.5 mm) filter thread
  • 3.5 nm FWHM (to harmonize exposure time with O-III/S-II), recommended for fast optical systems f/3.4 to f/2.3
  • 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
