Reprocess of Jupiter data from March 16

[michael.h.f.wilkinson]

Fiddled around with settings, and found that first scaling up with 1.5x drizzle in AS!2, processing in Registax, and then slight down-scaling gives me the best results. The best RGB image was the last (not too surprising as seeing clearly increased with altitude).

 

I also made two animations, one cropped:

one wider view showing a moon:

I also tweaked the IR result in a similar way:

Cropped

Wider view

Not too bad on a night with mediocre seeing

Very nice set Michael. A good result for all your hard work.

Nice images Michael - shows you don't have to have a C14 for planetary!

Interesting that the background colour (eg between the two belts) is nearly white, or even slightly blueish; my images (and my visual view) are always the same, and yet I note that many published images (eg front cover of AN this month) show the background colour as creamy-ish, like Saturn. I wonder which is more accurate?

Cheers, Chris. I think the colour is largely due to the auto-colour balance button in Registax. In reality the colour is roughly beige (assuming daylight adaptation of the eye), but that does not mean we would perceive it that way if we were close to Jupiter, as the eye tends to do an "auto-white balance" itself.

Hmm.....maybe. And yet if you look at both Jupiter and Saturn with the naked eye, Jupiter always looks blue-white, like a fainter Venus, and Saturn definitely creamy yellow (as a spectroscopist, I fret/OCD about colour rendition).

Lovely set of images, plenty of detail visible there.

Excellent stuff !

On the animation, I like the way that you can see suggestions of the different rotation rates of adjacent belts. Very nice

Terrific images Michael, very nice indeed.
