Baader O-III 31mm F2 Highspeed-Filter (6.5nm) CMOS-optimized: With 6.5 nm FWHM, this filter from Baader Planetarium is recommended for extremely fast optical systems from f/3.4 to f/1.8, like the Celestron RASA astrographs. The filters are designed to allow for 1:1:1 exposures. This matches the typical CMOS quantum efficiency and s/n ratio. The filters are optimized for CMOS cameras and will also work well with CCD cameras. Baader has designed this 31 mm Oxygen III (OIII) filter to be precision-grade and provide astrophotographers an excellent complement to their imaging setup.

This Baader OIII f/2 highspeed filter is CMOS optimized with Life-Coat. This coating is a hard coating that will not peel, flake, and will not physically degrade even in the most extreme weather conditions. This coating is also designed to withstand repeated cleaning with fine optical cleaning equipment. This coating is so durable that Baader is confident it will last the life of the filter.

Not only do the filters have sealed coating edges with the Life-Coat, but they are also hard coated with Reflex-Blocker and planoptically polished. All of the edges are blackened for increased contrast and eliminate any reflection that would come from light falling on the edge of the filter. The filters are also equipped with a filter-lead-side-indicator in the form of a frontside outer rim.
