I always take the flats on the night. If I image for a few nights I have sometime taken them the second or third night. As long as you make sure your scope is in focus and you haven't moved the camera at all you'll be ok. Makes sure you shoot your dark flats (bias) as well at the same time. Cover the scope and shot your bias.
If I don't use the camera I cool it down slowly to 0 then turn the TEC off. Never power off the camera when it's at -20c. I also ramp it down to 10,0,-10 then -20c when I start. Always did that. I never leave the TEC running for no reason. When I'm done with the camera I also always open it, vent it then store it in dry sealed pelican case.
