Thanks Carlton,
I know you can calculate it, but I kinda dread finding the specs for everything. I don't even know if my dew straps will even have published data (cheap chinese brand).
Besides the mount (gemini 2), the dew strap, moonlite focuser, USB hub, Laptop, Hard Drive, Polestar camera, ASI 1600 and 290 plus Temp control - I wonder how accurate it can all be when it depends on how far below ambient you want to cool things, how much dew there is, how heavy your scope is and how it's weighted, blah blah.
I think it may be more accurate to just determine it experimentally.
I'm thinking maybe I could just run it for a few hours till it drops below a critical level. What *is that level though?
It's been a while and I tend to forget things I previously learned. If you let the voltage on a battery run down, the problem for components connected to it is, what? I seem to have a vague memory that it draws more current, and damages capacitors?
So for devices designed to run at 12V, and given a car battery is 13.7V nominally, What voltage is 'flat'?
Cheers
Markus
