Hi
I was wondering if anybody could help me to attach my camera to a telescope (for little or no price)

I have a:
Pentax k10d dSLR
Panasonic Lumix DMC-TZ3
Orion Skyquest xt6.0 Dobsonian

I know there are adapters or like certain rings used to attach them to the telescope but is there some way I can make my own? With like a film canister or something?
Also if I were to buy one where can I find them/Cost?

Cheers
E
