This coating is so durable that Baader is confident it will last the life of the filter, even in the most extreme environments.\u003c\/p\u003e\n\u003cp\u003eIncluded in the filter set are three precision-grade 2\" threaded filters: an H-alpha filter, an SII filter, and an OIII filter. With 6.5 nm FWHM, these filters from Baader are recommended for extremely fast optical systems from f\/10 to f\/3.5, 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.\u003c\/p\u003e\n\u003cp\u003eNot 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. The filters are optimized for CMOS cameras, but they work great with CCD cameras as well.\u003c\/p\u003e\n\u003ch3\u003eBaader 6.5nm Narrowband 2\" CMOS Optimized Filter Set
