I’m using a Canon 600D with Stellarium, BYEOS for goto, acquisition, frame focus and capture
I find that the sensor temperature ( it’s actually the micro electronic chip board adjacent to the sensor ) increases dramatically when on live view for extended time during acquisition, frame and focus. When my capture plan is set with a 2 sec or 4 sec delay and pause taking say 40 x 2 minute subs, the temperature comes down slightly and stabilises through the early period / duration of the capture plan on a mild evening
I think the outside ambient air temperature is more of a governing factor when experiencing higher than expected camera sensor temperatures during your capture plan
I think if I set my delay and pause to 5 , 10 or 20 seconds during a hot summers night it’s not going to achieve much of a reduction ( ie: the use of extended live view initially heats up your camera very quickly and never quite recovers to an acceptable temperature )
My 2 cents .......
