Jupiter Nov 2024
The Shadow of Io and the Great Red Spot
I used the 2700mm f15 Skymax 180 scope for this shot but doubled its focal length to 5400mm with a 2x Powermate.
Prior to my session, I used Stellarium to look for interesting interactions between Jupiter and its moons and finally found what I was looking for. Io was to sit just outside Jupiter’s disk on November 15th, with its dark shadow projected onto the planet’s surface and the Great Red Spot front and center. The principles were projected to be in position by 11pm. It took nearly two hours to get the scope set up and cooled down but I still had plenty of time before the big event.
I used the ZWO 585, making SER files in FireCapture at about 14fps, stacked 1,588 individual frames in Autostakkert, sharpened with Registax and tweaked in Lightroom.
