Baader Highspeed 6.5nm 31 mm CMOS optimized filter set (H-alpha / O-III / S-II)
This new generation of Baader CMOS filters features:
- CMOS optimized Baader filters
- Increased contrast
- Increasingly narrower pass bands
- Reflex-Blocker™ coatings for the greatest freedom from halos, even in the most adverse conditions related to auxiliary optics
- FWHM in each filter category carefully designed to allow 1: 1: 1: 1 exposures, combined for typical CMOS quantum efficiency and s/w ratio
- Filter thickness identical to existing standards, with extreme care for parafocality
- Blackened edges all around, with filter lead-side indicator in the form of a black outer edge on the front side, to additionally eliminate any reflections due to light falling on the edge of a filter
- Each filter individually coated, with sealed coating edge (NOT cut from a larger plate with exposed coatings)
- Life-Coat ™: increasingly harder coatings to allow for a coating that will not age for life, even in the harshest environment
Summary key features:
- Baader H-alpha / O-III / S-II 31 mm" x 2 mm" high speed filter set - Precision grade
- FWHM of 6.5 nm, recommended for f/3.4 to f/1.8" optical systems
- Specially designed for special filter requirements when used with fast optics such as astrographs Celestron RASA
- Reflex-Blocker ™ hard-coated and planoptically polished, with sealed coating edges (Life-Coat ™)
- Blackened edges all around, with filter lead-side indicator in the form of a black outer edge on the front side
- Optimized for modern CMOS cameras, but excellent for CCD camera technologies
