Having bought an 8" goto dob for my son I will be wanting to set it up for easy use for him. Assuming perhaps a heater for the eyepiece, what sort of battery capacity are people getting full nights use out of?

I am hoping to be able to use an SLA physically small enough to mount inside the base in front of the azimuth motor as it will be one less thing to trip over. I can hopefully test it soon for myself but how many amps do these things need for slews?

I am working on the assumption that he will be likely to hop around with heaps of slews over a night at least for the first year or so, so a bit of extra capacity would probably be wise compared to a set and forget user who observes targets for extended periods.
