Can't comment specifically on what damage might be done however, if it's any help, my AZEQ6 flashes it's light at me (this is in indication of under voltage) at about 11.6V...
This is a fairly consistent figure with most 12V equipment in my experience... whilst some things will let you go lower without too much risk..
The question is... as you say... what can our gear safely tolerate... I'd suggest you don't want to go below about 11.8V as a margin of safety.. but, that's just my 'best guess'
For most of the 'brand name' gear, you should be able to find current draw on the manufacturer's site.. or sometimes, if it came with a 240v power supply, it might be on the power supply...
I have the cheap 5v Chinese dew heaters too, from memory, they work on about 2.5A @ 5v... so, I use approx 1A draw in my 12V calculation, which allows for the fact they aren't on all the time too...
For your camera, I know the ZWO's call for 12v, 3A supply for the cooling system so.. that might be your starting point?
Experimenting could be expensive... as you say, depends what happens to your gear if you undervolt...
