BAADER CMOS SHO F/2 HIGHSPEED FILTER
New in original cases $1400 posted

The new Baader CMOS-optimized SHO 3.5 / 4nm & 6.5nm Highspeed F/2 filters are precision-grade narrowband filters with high transmission at their respective emission lines. 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 3.5 - 4nm bandpass make these ideal for imaging under light-polluted skies. The 6.5nm versions are recommended for most cases where there is not a great deal of light pollution.
