Hi Tobias,
Junocam’s camera is of the push-frame variety. That means that rather than taking a single photo of a scene, it actually creates a single photo by combining multiple strips of “exposures” or scans. So if you want to truly process the “raw” images you’d also need to deal with the geometry of combining the individual strips into their single image. Personally I’m happy to skip that part and focus on processing the final composite image - which itself is pretty challenging.
I should point out that Junocam’s images all have a brownish-yellow color cast to them. For me, eliminating that while boosting the other colors has been a real challenge. I did write about processing Junocam images back at the start of the year: Image Processing and the Juno JunoCam which you may find useful if you want more background on the subject.
Great work age. I’m currently using that image as a desktop wallpaper.

Tone curve and some sharpening in darktable, cropping and changing the canvas size in gimp.

Ah ha - so its not just me who saw that dolphin shape. I didn’t even know there was a web page about it. Thanks for sharing the link
Yes, I also “saw” it. Funny!
All kinds of things in RawTherapee 5.4-dev: Dehaze, Soft Light, Gradient, RGB levels, color channels. Nothing by way of sharpening or wavelet enhancement.

Btw. here are two interesting links with information about the raw files:

I was not particularly preoccupied with the colour or details this time. Just wanted to provide a nice presentation of Jupiter. I typically use image stats to process the photo; however, the black and fringe presented a unique challenge. I had to go back and forth between the mask and the original and masked images. Likely much easier with a GUI, oh well… 
1. gmic → generate mask A → mask out black, fringes B → extract region C → gather stats C → adjust brightness, contrast (curves) B → crush blacks, soften edges A B → rotate → crop → frame → sharpen (LoG) → resize
Zoom 100% and enjoy!
