Peter W mentioned that the sbig can go to -20 on 20deg nights. but that'd be pushing it hard.
can any stf owners comment on the cooling and what they normally reach?

Thanks

It's not just about cooling performance. SBIG are rather conservative with their cooling specs....(they have to guarantee their published delta T )

A little known fact is they also have a patent on holding CCD chamber temp stability to around 1/100th. The end result is a much cleaner and consistent dark calibration... which far outweighs an albeit higher but inconsistent delta-T IMHO.
