Jupiter & Io 2017 Apr 03

I did a quick Twitter thread talking a bit about what goes into processing one of these Jupiter images. This particular one I also wanted to show why I didn't like the official release image released last year. For that image, the sides of Jupiter were trimmed off, making it look a lot rounder than it is. The clouds are also a bit misaligned in some places, resulting in some odd colorful fringing if one looks closely. It's been bugging me for quite a while now. I'm afraid of seeming antagonistic about things sometimes.


Here's a link to the thread turned into a "moment":


Did some final tweaks after the Twitter thread including filling in the left side and some sharpening. Note that part of Io was missing in the F631N data, so some of the F502N data was adapted to make the moon appear complete. The end result is probably not much different visually from how it would have appeared if Io wasn't slightly off the edge.
