Robofocus has a 4 outlet power control box that I use. It can turn on a light for flats, or do whatever. I use it now to turn on red lights before I go tripping out there to check something, another outlet for toggling the power to the camera (needed for my DSLR), outlet #3 controls the 12VDC power supply, and I intend on connecting one to an autoflat light panel on the inside of the observatory. I was going to use it to shut down all the power, but then I can't use it to start it up again because my robofocus controller is connected to a powered USB hub... which needs to not be on the robofocus controlled power module.
