BAADER CMOS O-III F/2 ULTRA-HIGHSPEED FILTER Clearance2024 iPolar and more Counterweight shaftThe new Baader CMOS optimized O III 4nm 6. 5nm Highspeed F 2 filter is a precision grade narrowband filter with a high transmission at the Oxygen III line at 500. 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
