Where were you 18 months ago when I bought my first cooled ccd? That is an awesome post - thanks for all your effort. I'm sure many will bookmark that one.
I have just bought the QSI - a trade up from the ST8300 I hope. I agree re the guiding issues with the RC8. I had a f4 SN which was pretty forgiving. The change to the RC8 was a bit of a challenge. It can be done but you need to get your polar alignment right.
I agree that the 8300 is a cracker when paired with the RC8. It gives a nice field of view and allows binning if the seeing is less than ideal.
