Thanks Dunk, that's a good idea, I will try ISO1600 running as cold as I can. I don't need a cool down interval for the sensor running at setpoint of -5C. As to night time ambient and summer seeing wobbles, I try to delay imaging until after midnight, to allow the earth to output retained heat and the atmo to stabilise. It helps a littlle. Not an issue in winter but then dew and optics heating is more an issue.
