Astrodon I-Series LRGB and 6nm H-a Square Filters

The CFW-4-5S holds five 50mm square filters and is CNC machined to accept Astrodon filters without the need for o-rings or spacers. The CFW 4-5S is designed for the new, large format cameras that employ sensors such as the KAF-09000, KAF-16800 and Fairchild Imaging CCD3041.
