Not really a question - more of a comment. Last night I used 2 dew control heat straps plugged into my 12V battery. Had them plugged for a couple of hours while I was mucking around with the scope. Tried to slew to a target and noticed that the mount was struggling and it sounded like it was skipping gears. Investigated and realised the battery was almost completely flat
Had no idea how quickly dew control drains the battery! Will be better prepared next time though
