BAADER CMOS S-II F/2 ULTRA-HIGHSPEED FILTER TESTAR-IP 50 mm diameterThe new Baader CMOS optimized S II 4nm 6. 5nm Highspeed F 2 filter is a precision grade narrowband filter with a high transmission at the Sulphur II line at 671. 7nm. The Highspeed F 2 versions are specifically designed to work very well with modern highly sensitive astronomy cameras and telescopes with extremely fast focal ratios faster than f 2. 3 such as the Celestron RASA astrographs. The ultra narrow 4nm bandpass makes this ideal for imaging
