- Baader H-alpha / O-III / S-II f / 3 Ultra-Highspeed Filter Set - Premium Grade
- 3.5 / 4 nm half width (to harmonize the exposure time of H-alpha with O-III / S-II), recommended for extremely 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
- Enables the highest contrast even with the strongest light pollution, minimizes the size of the stars, makes the finest nebula details accessible - indispensable under Bortle 9/8/7/(6) sky
- Reflex-Blocker ™ hard-coated and optically polished - with sealed coating edges (Life-Coat ™)
- Blackened edges all around, with a filter front indicator in the form of a black outer edge on the front
