Fortunately mine is a USB 2.0 15 fps @ 800 x 600 and 7.5fps at 1280 x 768. Not bad for a webcam, Found of the resolution 800 x 600 was the most optimal for size and clarity, whereas I didn't capture enough frames for 1280 x 768 too really test it properly.
With lower fps the only other thing is to get enough frames with minimal field rotation as I have found with the 450D. It looks as though I get 6 -8 frames per seconds.
I am still reprocessing and have had some improvements too, no imaging for a while as my mounts parts arrived and working on some new parts to improve mount stability.
One of the next things is to create some darks and flats for the webcam to improve further imperfections possibly.
I would say overall must have been great weather. How long before that happens again, I can only wish.
