  • 47.4 mm (2" w/o cell) x 2 mm Baader CMOS H-alpha f/2 Ultra-Highspeed Filter – Premium Grade
  • 2" Filter removed from filter cell, specially selected for use with 2" Filter sliders of the Baader FCCT (Filter Changer Camera Tilter) for RASA 8" and QHY cameras (various versions available)
  • 3.5 nm FWHM (to harmonize the exposure time with O-III / S-II), recommended for extremely fast optical systems from < f/2.3
  • Specially designed for the special filter requirements when used with extremely fast f/2 optics like the Celestron RASA astrographs
  • For highest contrast even at strongest light pollution, minimizes star size, emphasizes finest nebula detail – indispensable under Bortle 9/8/7/(6) skies
  • Reflex-Blocker™ hard coated and planeoptically polished – with sealed coating edges (Life-Coat™)
  • Blackened edges all around, with filter-lead-side-indicator in the form of a telescope-sided black outer rim
  • Optimized for modern CMOS cameras, but likewise excellent for CCD camera technologies
