DC Power Supply Question

[Armitage]

I bought a GoTo telescope recently ... it uses 8 AA batteries in series - 8*1.5V = 12V
The battery pack connects via a connector like you use for a 9V battery.

Is there any reason I couldn't take a 12V block transformer and solder one of these connectors to it to make myself a AC adaptor and save a bunch on batteries? Seems reasonable to me.

go for it. just make sure it's 12v DC

The transformer would give you AC
You need DC
A full wave rectifier is in order

Well yea ... what I mean is one of those block things you plug into the wall that gives you DC for your electronic goodies. Transformer + Rectifier in one nice little package.
