Description

This is the first heavily processed photo, but it was taken on a cloudy night and isn't terribly great. It was just fun to put together and contains the first version of a photo of Jupiter that contains any sort of atmospheric detail.

I used Lynkeos to stack a 30s video of Jupiter to get the detail and hints of atmospheric banding and I hand-selected the only of the several shots of the Galilean moons with an overexposed Jupiter to get the clearest of those shots. I then calibrated both images in PixInsight, and used the GIMP to layer them. Jupiter was masked into the top layer, Ganymede and Callisto masked out of the moon photo. The master dark layer was used as the background layer. These were then combined and flattened to produce this image. FIve minutes of shooting, a few hours of processing. For how the conditions tonight were, I'm happy with how it turned out and more importantly I have a good handle on the process for doing this once I capture better quality images.
