Great Red Spot and Transit of Ganymede across Jupiter 4/21/2015

I set up the scope and camera tonight with more hope than expectation but was able to capture a transit of Ganymede across Jupiter and the Great Red Spot, maybe the first time I’ve ever been able to capture it.  Details: 8″ SCT at f/10 on an ASGT mount, ZWO ASI120 camera best 25% of 2000 10 millisecond frames.
