Baader 6.5nm f/2 Highspeed Filter-Set – CMOS-optimized (H-alpha / O-III / S-II)

  • Baader H-alpha / O-III / S-II f/2 Highspeed Filter Set – Precision Grade
  • 6.5 nm FWHM, recommended for extremely fast optical systems from f/3.4 to f/1.8
  • Specially designed for the special filter requirements when used with fast optics like the Celestron RASA astrographs
  • Reflex-Blocker™ hard coated and plane optically polished – with sealed coating edges (Life-Coat™)
  • Blackened edges all around, with filter-lead-side-indicator in the form of a black frontside outer rim
  • Optimized for modern CMOS cameras, but excellent for CCD camera technologies

3 filters set
