BAADER CMOS S-II NARROWBAND FILTER Size:2" The adapter fits into theThe new Baader CMOS optimized S II 4nm 6. 5nm filter is a precision grade ultra narrowband filter with a high transmission at the Sulphur II line at 671. 7nm. It is designed to work very well with modern highly sensitive astronomy cameras and telescopes with focal ratios between f 15 to f 3. 4. The ultra narrow 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
