Hello,

I'm wanting to capture pictures of the Ronchi image of a 12.5 f3.87 . I have the Ronchi setup but was wondering if anyone had any experiance or recommendations with using a webcam to capture pictures of the images. The real reason is that I've got something going on with the figuring of the mirror that I don't quite understand and I'd like to be able to post the images here to get some advise.

Thanks Preston
