I have QHY10 Cooled CCD camera. I notice cooling the camera is very slow compare to EZCap software provided by QHY. Here is what I see.
Temperature Setting to -15C
EZCap can reach this temperature easily in a minute or so. SGP take more than 30min and it get to -14C instead of -15. EZCap actually reached -17C, so camera is capable to achieve this temperature. I tried to set temperature by using set button or use cool down with connect -15C in 1m setting. Cool down with connect sequence finish in 1 min but won’t reach -15C. It was like 7C.
Even I pre-cooled with EZCap and switch to SPG right away, SGP report much higher temperature and won’t cool quickly.
Anyone use QHY10 with SGP? Is it cool down quicker than 30min? Does SGP has limitation how fast it cool down camera?
I understand manual stated slow cooling is better but I feel more than 30min is too slow.
