After about 20 hours of data crunching in RegiStax, my animation is finally complete!

The animation starts at 11.00 pm and finishes at 3.09 am. The moon closer to the equator is Io, and the one at the bottom closer to Jupiter's south pole is Ganymede. Ganymede also transits over the Great Red Spot... "action packed" according to Clayton/Rob :)

The seeing varied from none (total cloud cover) to pretty good. There was only "pretty good" seeing for just over 20 mins during the entire evening :( Each frame was produced with identical settings by stacking ~ 2 minutes of video taken at ~ 10 minute intervals. Here's the raw 2 minute video clip with the best seeing of the evening:

Technical details: William Optics FLT-132 on NEQ6, 5x TeleVue PowerMate, Canon 5DmkII. EOS Camera Movie Record in 5x crop mode at ISO 800 and 1/30 sec, best 10% of ~ 3000 frames for each video stacked in RegiStax. Aligned, processed, and animated using Photoshop.

Nice job Dave :thumbsup:
You can't slow it down just a tad can you :question: I find it hard to take in all the detail at that rate :confuse3:

Thanks Rob! Good suggestion - I've added a slow version of the animation plus timestamps to both. Not too much detail to take in with the poor seeing unfortunately :(

In case anyone's interested, I've assembled a short video with some recent time lapse footage of Jupiter/Orion rising and the above double-transit video.

Excellent work! Some nice sharp frames amongst the animation.

Well done!

Thanks everyone! I used an almost identical process to capture and render each frame of the animation - the main difference between frames was seeing. I was surprised at how quickly it changes, and how much it varied between good and bad (within only a couple of minutes).
