hi
anyone with an stf8300m know if it has single or dual stage cooling?
Peter from ATS wasnt too sure but did say that it can go to -20 in summer.
the qhy9 seems to have better cooling and a heated window although I'm not too sure if that alone should be the basis for a decision.
the qhy shutter is also slower from other threads here.
any stf owners able to chime in on the cooling performance?
thanks
Alistair
