Product description
- 2" x 2 mm Baader CMOS H-alpha / O-III / S-II f/3 Ultra-Highspeed Filter Set – Premium Grade – with 2" (M48) filter thread
- 3.5 / 4 nm FWHM (to harmonize the exposure time from H-alpha with O-III / S-II), recommended for fast optical systems from f/3.4 to f/2.3
- Specially designed for the special filter requirements when used with fast f/3 optics
- 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 plane optically 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
- Mounted in Baader Low Profile Filter Cell (LPFC) – 6 mm height
