The Dutch Observatory

I finished processing my RGB images of Jupiter with Calista, its shadow while Ganymede was tracking behind the planet.  Here two images.  The first one from before the shadow left the limb and the second after the shadow disappeared, but before Ganymede disappeared in Jupiters shadow.  (See animation on the previous post)

Conditions were a lot better than we have had in a long time. Seeing was probably up to 6 and transparency up to 8. I made a total of 48 channel images between 3.46 and 4.46 UT of which a series of 6 was Red only.

I did image Jupiter and two of its moons. I made an animation using the red channels only of Calista passing over the disk while its shadow left the disk, while Ganymede was passing behind Jupiter and disappeared in Jupiter’s shadow.  I will be trying to use the RGB images to make a color version, but Ganymede moves pretty fast accross and I have problems lining up its color channels.
