Hi,
Thanks for all the info.
you're right, there are several other factors to get right, and I'll probably set it at -16 or so most of the time. thats why i thought i'd ask first.
the STT has some serious cooling but it would blow the budget.
i'm happy with the stf8300m and an sx 7 position wheel.
the lodestar is arriving tmrw, now to order the rest and fix my image circle issues.
silly question perhaps, if i point to a full moon and keep a paper at the ccd focal plane, would i be able to see the illuminated circle?
cheers
Alistair
