With my big gun I observed Jupiter and its four big moons in a very pleasant position. From left to right we see Io, Ganymede, Callisto, Ganymede’s shadow and Europa. The only thing missing from this great vista is the Great Red Spot, as it is frequently missing when it should not.

The gear: ASI 224MC, TS Optics ADC, Barlow, N 250/1200, HEQ5.
