Guys,
I really appreciate your suggestions! I'm going to over San Jose for AIC next week and I plan to ask a lot of people about this subject.
Slawomir, I have certainly looked at the ATIK 4120. It would give a fairly over sampled image and a FOV actually smaller than my Trius currently. For those reasons alone I think it's not the "answer." (.65 arcsec, 30.7 x 46.1)
Lewis, when you say the the Sony eats the Kodak chop (er I mean chip!) I assume you mean in terms of QE, darks, the usual?? The Kodak does win in terms of the FOV (except when considering the QHY12 which nobody commented on). I did receive a not too favorable comment about the QHY12 in terms of build quality. Too bad because on paper it seems to fit the bill pretty well, though without the high QE of the newer Sony CCDs.
Greg, I think Rally points out some important things to consider re the KAI8050. Probably for my purposes the SC version wouldn't be of much use given I only want the colour data to combine with high quality luminance from my TEC180. The SX25 & 26 are interesting cameras. The SX would give me a resolution of 1.27 arcsec and FOV 55.4 x 82.7. The FOV is great but I'm not sure the resolution is what I need given the TEC180 is at .88 arcsec. The SX25 is even worse in that respect giving 1.64 arcsec.
Rally, You have given me lots of good info to ponder. I really appreciate it and I'm thinking more and more that the KAI8050 isn't the right chip for my needs.
It seems a given that if I move from a mono camera (for colour) I will be giving up resolution somewhat of a similar nature to binning a mono camera 2x2 but without getting any gain in sensitivity. So, compared to a mono camera R & B would be 25% of the pix active, Green 50% of an array of 4 pix. Now, since it "was" common practice to bin colour data when doing LRGB it would seem prudent to not make matters worse by using a camera that under samples compared to my L data. Is that correct? If so, I think I ought to stay in a range fairly close to .88 arc-sec. I don't expect to save any time getting colour data, but I do think it all might prove easier. Maybe I'll have a better feel for all this after my trip.
Thanks all,
Peter
