How do you obtain proper focus on a webcam?

Hi all

Just thought I'd take the new ZenithStar 66ED out tonight for a spin and thought as I was setting up "time to use that ToUcam that's been sitting there since I bought it". So... this was going to be my first real go at imaging. I rigged it all up and.... well... think that it's really difficult to achieve good focus. How on earth do you guys do it? I haven't fiddled with these particular images in PhotoShop, but I have tried on others. Applying various sharpening algorithms simply overcooked the images and contrast looked horribly overdone. Is there a simple method? What's the secret of focussing with a webcam? Resolution is only VGA (640x480) so I suppose that great results are going to be hard to get anyhow. Focussing "on-screen" in real time is very difficult - I could not get any sharper that these are already - 10:1 focus control and all.....

Time to go DSLR I think. At least I can look at an image on the focal plane as I focus......

Any advice?

Cheers and thanks everyone
Chris
