Europa occulting Ganymede, 8th May 2009 18:02:56UTC - 18:12:08UTC
Here's an animation of Europa occulting Ganymede on the morning of May 9 (May 8 18:02 UTC or thereabouts).
The seeing was not very good, and so I was only able to use 250/1200 raw frames for each final
frame in the animation. You can see that the seeing improves a lot toward the end of the sequence.
Astrodon I-Series filter (Red)
PGR Dragonfly2 camera @ 38 fps
TV 5x powermate @ 7.7x.
Scope was LEXX
NOTE: Images resampled to 300% before processing. Io measures 0.8 arc seconds and Ganymede measures 1.4 arc seconds.
Each animation frame is approx 31 seconds of raw data (1200 raw frames) and the best 250 as chosen
by ninox were stacked and processed in registax.
There are 17 animation frames in total spanning the period from 18:02:56 to 18:12:08 inclusive.
