Jupiter 2012 September 22

Here’s some images from the 22nd, poor seeing as usual. Ganymede is just coming out of occultation.

The 03:56.8 image is made from a single RGB set. A hint of detail is visible on Ganymede.
The 03:53.9 image is a merger of three RGB sets using WinJUPOS (technique suggested by Dave T). These cover 03:48 to 04:00, so Ganymede is smeared by its orbital motion. One sees however that a lot of sharpness on Jupiter is gained by the 12 minute merger (and re-sharpening).


I also provide the three red images in a separate file. They were produced by 150% drizzle in Astrostakkert 2.
