Hi all,
Is there a golden rule to help how long the delay should be between subs to let the sensor cool.
At the moment i use 5 seconds between everything from lights, darks, flats, and bias.
I'm not guiding so im lucky to get about 2 minutes or less.
Im keeping it simple now so no laptop to see the temp on each frame.
What im trying to workout if i do longer subs then do i need longer cooldown time.
Im using a moded 450d

Cheers
Andy
