Baader 6.5nm f/2 Narrowband – 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/10 to f/3.5
- 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:
- H-alpha 6.5nm Narrowband
- OIII 6.5nm Narrowband
- SII 6.5nm Narrowband
