Specifications

Clear (C) filter
Optional clear filter (optical glass with AR coatings) of the same thickness
like RGB filters can be used in addition to (or instead of) Luminance filter
to use maximum chip QE for luminance images. Optical glass is used
instead of simple empty hole in filter wheel to ensure proper focus and to
eliminate refocusing when changing from filtered to unfiltered exposures.
The Clear filer can be also combined with RGB so it is possible to install
CRGB filter set and to leave one empty filter wheel position.
