Arriving home from work tonight under partly cloudy skies, I did not even bother to open the observatory roof. This turned out to provide good karma as my poor planning led to skies that were crystal clear at 9 PM. While the transparency (clarity of the atmosphere) was reasonable for observing Jupiter, the seeing (atmospheric stability) went from average to poor rather quickly between 9 and 10 PM. This was unfortunate as tonight was a transit of the Galilean moon Io and its shadow. Regardless of sky conditions, being the faithful amateur astronomer that I am, I took several videos through my 11-inch Celestron Edge HD SCT and my ASI120MC camera in order to stack the frames and create an image of the event.
First up, is a stack of 2 images, each of which itself represented a stack of approximately the best 450 frames out of a 60 second video. That is Io's shadow cruising through the south equatorial band. Just think, if you were on Jupiter standing in the shadow you would be seeing a solar eclipse!
