12V vs 13.8V?
How safe is using a 13.8V power supply to drive astro kit designed for 12V? The reason I ask is I use a Losmandy G11G and it is recommended to drive that at 13.8V (the voltage your car's "12V" circuits run at with the engine running) thus I have a 13.8V power supply.
I figured it is ok to run the dew heaters at this level, but what about my FW and focuser, it is the latter that makes me nervous - I do not want to risk the stepper in the Moonlite but likewise I would like to minimise the cable clutter - I already have to deliver 13.8V (mount), 5V (USB hub) and 3.3V (ccd).
