The Baader CMOS-Optimized RGB-G Green Filter for FCCT is a 47.4mm round unmounted 2" bandpass filter suitable for f/15 to f/1.8. The balanced RGB design allows for the capture of subframes to be taken at the same exposure time.
This RGB filter is anti-reflection and made with an extremely high transmission of the green color channel. Meaning that it reduces stray light and any unprecedented reflections.
Optimized for modern CMOS cameras, but will also work well with CCD camera technologies.
This filter has blackened edges all around it, and also comes with a filter-lead-side-indicator to differentiate which direction to insert the filter. With a Reflex-Blocker™ hard coating, this filter is also plane optically polished with Life-Coat™ sealed coating edges.
