Thumbs up Jupiter + Ganymede transit animation!

Hi all

I finally processed all the data from the session on the 15th in order to make this 14 frame animation. It took ages! I had to process each avi twice, once for Jupiter and once for the moon..

30 passes through registax, astraimage and photoshop, and here is the result.

Each avi was captured at alternating fps, 15fps (1/15s exposure) and 30fps (1/30s exposure) so unfortunately there's some colour balance/brightness mismatches but it's not too bad.

The seeing improved as the session went on, and the last 4-5 images are amazing. Every image has some detail on ganymede, though in the earlier images where the seeing was less than average, there's more artifacts than real detail. The last few images have incredible detail on Ganymede.
