Hi folks,
I recently bought a Skywatcher 14" GoTo Dob and want to buy an appropriate pwer supply. I'm torn between buying a battery (which one?) and a separate charger, or buying one of those combo products called Jumpstarters which have a battery and charger built in, but are bigger and heavier than a battery alone. I'm concerned about the weight and size of these types of things sittin gon the base of the scope as it motors around azimuth. Money is very tight, so I need an adequate power supply for a typical 6 hours viewing session, but not spend too much of the ready.
TIA
Rob
