Hi John.
I can't answer the DSO question, but for ToUcam answers keep reading
Most of us got our ToUcams from
Telescopes & Astronomy in South Australia. Matt is a good guy, but busy.. Send an email, but i'd also follow up with a phone call because sometimes it might take him a while to get to your email.
Last I checked, they were $145.
You'll need a 1.25" adapter, he has these too, for $45. They simply screw into the ToUcam housing after you unscrew the lens.
You can get an IR filter, I wouldn't bother for now. I haven't noticed any difference with or without, yet. It's a cost you can expend later if you feel the need.
That's it, that's all you need. $10 postage and you're ready to image the planets/moon.
Of course, it's USB 1.1 and you need a laptop with USB port.
Get K3CCDTools version 1 (free) to use as your capture software.
Get registax (free) to use as your registering/stacking software.
That's it!
You don't live far away, i'm happy to come to your house to show you how to use it if you wish.
