During this morning, Ganymede played hide and seek, emerging from Jupiter’s shadow, just to disappear again, behind Jupiter’s limb. I used my usual planetary setup, ASI 224MC, TS Optics ADC, Barlow, N 250/1200, HEQ5 installed in my  balconic-balcanic improvised observatory. The seeing was, this time, good to very good, with Saturn’s Cassini gap visible on the live view images, and Jupiter GRS also obvious on the live view. It’s mostly not the case, I must add. The moons are Io, Ganymede and Europa. Ganymede was part of the original recording (it was in the ROI selected for the planet), while Io and Europa are composited onto the image.
