Thanks for the help fellas.

I'm going to power the SBIG from a 12v 80AH deep cycle. I'd use an inverter Bojan, except that the power supply I recieved with the camera is a 120vAC jobbie, not 240. I could use a 240-120 step-down after the inverter but think that there'd be a few inefficiencies creeping in.

I'm now thinking that an AT power supply from a PC might do the job. It needs +5vDC @2A and +/-12vDC at 0.5A. They're nice and regulated switch-mode units and have plenty of power in reserve. Running off my 500W pure sine wave inverter it should work nicely.... I think.
