Hmmm.. I thought I'd get the new D40 that Jenny bought me out tonight for a crack at the moon at prime focus on my little WO 66mm refractor. Wow, getting to know how a DSLR works in comparison to a webcam is going to be pretty drawn out affair I think. Had to laugh given that I took 25 frames and stacked them in Registax - and while it was doing that it was taking nearly a full Gb of system memory, yet the final result is a 1024x768 jpg which turned out at 63kb.
Good fun though!
Cheers
Chris
