I know that everyone raves about the Philips Toucam, but does anyone use any other type of webcam for astro imaging? I am completely green when it comes to webcams. I have $50 of birthday money to spend and I was thinking of using it to get a webcam.
What features should I be on the lookout for?
Do all webcams have a removable lens and a standard screw thread?

I did a Google search for Toucam on Australian sites to see what shops sell Toucams, but I only found some EBay listings. Who does sell Toucams?

Sorry for all the questions!!
Any insight will be greatly appreciated.

Cheers.
