Hi Peter,
Thanks for the interesting comment on the Power Tank. I got one second hand recently with a scope I bought and find it very good to use but I was a bit dubious about the charger. It has the US plug so I have to use an adapter. The previous owner had it sitting around for some years so the battery was dead. He replaced it but I have been thinking about the best way to keep it in good condition. After reading your experience I am going to go ahead and ditch the charger and do a connection for a good trickle charger. I think I'll get rid of the jumper leads too as they get in the way. One of the first things I did when I got it was to remove the halogen globe from the spot light so it can not blind anyone if it accidentally gets switched on on the observing field!
Cheers,
Ross...
