Moon shadows on Jupiter
Three of 20 images of the shadows cast by Io and Ganymede on Jupiter during a double shadow event, one near the start, one in the middle and one at the end. Io can just be made out on the upper two images as a white spot between Ganymede's shadow and Jupiter's red spot. In the lower image Io has just left the planet's disk and shows up clearly.
8" Edge SCT on AVX mount.
ZWO ASI120MM-S camera with filter wheel and TV Powermate barlow to give focal ration f/25.
Captured 1000 frames in each of R,G and B filters for each color.
The best 30% for each filter were stacked in Astrostakkert. Sharpened in Registax. Winjupos was used to derotate the R,G and B frames before combining to make RGB color images.
Post processing in ACR and Photoshop.
