My son and I seem to have been bit by the astronomy bug. The last month or so since we got our Onesky has been quite an adventure including getting another scope from a neighbor (Tasco 130) price was right and couldn't pass on it even though I sill haven't figured how to collimate it yet but its working okay for him.
For now we are enjoying planetary viewing since the light pollution here in Stevens, Pa seems to be keeping dimmer objects out of view. We have been using phone holders to take pictures of Jupiter and Saturn with okay results but would like to try to get some better pictures and increase our experience with a Cmos camera and a lap top. Obviously on nights away we would need to power the computer and camera.
The equipment I have so far is just the laptop, however I am looking at a ZWO ASI120MC-S camera, other than that I'd like to keep it pretty basic to learn stacking photos which would be done at home. I'd like to be able to power them for 2-4 hours, probably less at this point. For now I'm not running any electronic goto or tracking bases so its strictly planetary, with quick bursts while they are in frame.
My thoughts at this time are using a led acid or possibly a deep cycle 12v battery and a converter. For now I don't care about the weight, just looking for advice on what you would recommend for power supply just to get us on our feet to see where this goes.
