Here's what Alan Leggett had to say about it on the QCUIAG
"Hi Folks - Some time ago I posted some info about a ronchi
screen to help you focus, and Richard Shell who is the owner of
Stellar Technologies was going to try making a focuser that
could be calibrated to our WebCams. Well, I received one 2 days
ago and last night I calibrated it to my WebCam. Within seconds
of me finding the object with a 26 mm plossl, I changed over to the
ronchi screen, refocused using the ronchi, replaced it with my camera
and hey - presto - there it was all focused on my computer screen.
All in 40 seconds! It's just brilliant and no more hassle!"
