Hi guys,

I'm looking at upgrading from my manual dob to a full go-to one. When I emailed Andrews Comm they suggested getting the Celestron 17A/h PowerTank for $249. However, after doing some research about this power supply, it seems that the general opinion has been that it's not worth spitting at.

Some suggestions I've seen for alternatives are to just get a jumpstarter from Super Cheap Auto. Looking at the price difference between this and the "official" power supplies for telescopes, they're pretty attractive. Does anyone have any suggestions or information about what the best option here is? Is there any modding necessary to make one of these compatible with the telescope? And perhaps most importantly, do I run the risk of frying the motors/controllers in the scope?

Cheers

P.S. The scope I am looking at getting is a Skywatcher Black Diamond Flex-Tube 8" collapsible dobsonian.
