Ok, no judging, this was my first ever AP attempt with a webcam and 8" Dob.... 15 years ago... so from memory I dragged my Pentium 3 with CRT monitor and Philips webcam with lens removed and a 35mm Photo canister hot glued to the front (found it the other day actually) out to driveway.
Would line up tube ahead of transit of planet across the screen, wait, and take a short avi if it showed up.
Ahh the good ol days.... and I have to tell you, I was very very happy with the result at the time.
Cheers,
Justin
