About
A three-filter red, green and blue set for colour deep-sky imaging with CMOS and CCD cameras, with passbands chosen around the emission lines that matter and tuned against measured sensor response curves rather than published ones. UV and IR blocking is built into each filter. 31 mm round, with protective rings.
