Quick comment/question: I understand the argument when it comes to photographic use, but how about photometry/astrometry? If you wanted the same resolution from a OSC as a monochrome CCD for positional or magnitude measurement, you're not likely to get it, are you?
I suppose, given a sufficiently bright object you could measure position using raw data prior to debayering, but I wonder how accurate magnitude determination would be on a OSC camera, especially as visual magnitude falls off? IE, to what magnitude could you accurately measure visual brightness within, say, 0.1 mag, when a bayer matrix is present? I guess these figures will be specific to a given sensor chip, but I suspect that even the current generation of OSC systems is of semi-limited scientific use (depending of course on one's definition of "Scientific")?
Regards,
Eric
