Hi
Trevor runs that and more from a 5A 13.8 v regulated supply that I built out of a DS kit (back in the days when it was still DS). Don't muck around with batteries unless you have to. They are expensive and always go flat just when they are needed most.
The standard load:
1 G11 with Gemini
1 set dew heaters (Kendrick type)
2 computers (laptops)
1 camera
1 guider
1 fan on the 8" scope
