While recording the planet, I also exposed a few frames for the moons. Then I used Stellarium to align the properly exposed planet to the rather noisy background. The outcome had a surprise too, a 10.15m star I failed so far to identify. Below I show the steps of the process the picture went through from the stack, via composing, to the final image. Mimas is more like a wishful thinking — there are some lighter pixels there though –, but Enceladus is clearly there. The moons on the final picture are from the pixels of the original recording, the Stellarium layer was nothing but a guiding tool.
