Hi Bob,
I think there are several IISers with that camera who are very happy. If budget's a concern, you may also want to check out the
colour QHY9 - only $1,650 from Melbourne.
The
SBIG STF-8300C is a nice camera that has 1 second full-frame downloads. I have the mono version and I can effectively focus with a Bhat mask in real-time using full-frame downloads (the 383L+ has 10 sec full frame downloads) - though I usually use the faster focus/crop modes. The dedicated
OAG-8300 is very nice, but quite expensive on its own or
as part of a package.
I'm told the QSI equivalent is very nice too, but I don't know much about it.
