Jupiter, Saturn, Mars and Neptune - 14 Sep 2020

Melbourne had some nice weather 2 nights ago, as can be seen by a number of people posting from here . Callisto's shadow was crossing Jupiter while the GRS and the latest storm was also in view. I tried taking an extended video of Saturn, recording for 15 minutes and then using WinJupos to remove the field and planetary rotation from the video. then using normal processing techniques to stack the best 10,000 out of the 90,000 frames captured. The C-ring is visible, and also maybe the Enke Gap (but it may well be just a processing artifact). Mars is getting better, Neptune came out nicely but I got too tired to stay up for Uranus.

Jupiter shown at captured size, Saturn and Mars at 150% captured, Neptune and Triton at 200% captured, Triton artificially brightened and enlarged, colour cast not yet optimised (still working on that ).
