Thanks for the comments guys but I know you're being too kind on my noisy grainy blob
Gary, Focus could most certainly not be quite right, and I know I definitely need an adapter.. many times I almost bought the steadypix, many times I almost started making one of my own.
But since I got the webcam I didn't think I'd be using the digital camera to do much afocal stuff anymore.
But I guess, there'll always be times where the digital camera will be better than the webcam, like for full moon or full sun shots, eclipses etc.. so I might just take the plunge and get or make an adapter.
Have you got a picture or plans of the adapter you built?
