Thanks everyone - looks like all calibration types are done at the same ISO as the lights. Well that's nice and easy. Wish I could say the same for dew prevention. I spent just under an hour of imaging on lights of m27 last night plus all the rest of the calibration frames on top of that just to find out that most of my lights were near useless due to fogging by dew. Does anyone have any experience of using dew heaters? Do they do what you hope they will do? Sent from my iPhone using Tapatalk

Just a quick question everyone - should I be shooting my flat and bias frames at the same ISO setting as my subs and darks, or is there a more general ISO at which to shoot these calibration frames? Adrian Sent from my iPhone using Tapatalk
