Power supply
I would like to know if anyone has an opinion about what the best way to power my ETX-125 is. I've noticed that it goes through a set of alkaline batteries pretty quickly and could start getting exspensive after a while.
Should I get a Celestron powertank? Rechargeable batteries? or go to Dick Smith's and get a lead acid battery & charger?
The powertank seems a bit rich for what it is ($135), although it does look quite versatile.
Any help is much appreciated.
