Io was transiting Jupiter this night. The best seeing so far this season, I'd give it a solid 7.5/10. The definition was good enough I had to align for the planet and the moon & shadow separately and then merge the two.

This is a north up view resized up to 1.25X.

Captured with a Flea3 using FireCapture 2.1.

Comments or questions welcome. Thanks for looking!

No doubt Glenn one of your best! What great detail!Great work on processing all the key details! I guess I missed a potencial great seeing opportunity.

Another super image Glenn, a ripper in every respect.

The NEB looks a lot like the GRS wake. Lots of activity to look over. Simply gorgeous.

Thanks guys! Much appreciated. I must hasten to add that at least 95% of the result is due to a higher power!

Here is a later image in IR. Io is really bright at the longer wavelengths posing a problem in processing both planet and moon without Io saturating. I think this is the best compromise.

Thanks for looking!

Terrific image Glenn, one of the better ones so far this apparition I think. Just loads of great detail there...

Clear Skies,

Glenn, when you said that at least 95% of your result was due to a higher power I quickly glanced up at the image caption to see if you boosted the focal ratio with a higher power barlow; then I thought, "oh he means THAT higher power" :rainbow: I'm sure you're going to want to print this one for framing; it's truly superb.

Glenn,

Truly amazing and a processing technique I wish I knew how to do.

Thanks guys!

Pete, yes that is what I meant, and thanks for making me laugh! Of course the 95% figure is far too conservative!

Paul, I played with wavelets a lot to get this. I unchecked level 1 as shown below. Why it helped to give definition across Io without saturating the heck out of it I don't know. Normally I play with the Sharpen control (in addition to denoise) usually turning them down to something like .060, 080 etc. And when I resize up to 2.5X (Jupiter) or 4X (Mars) I start by setting the initial layer to 2.

For each outing I end up with a slightly different scheme in wavelets. Hence my wavelet directory has many entries - so appending the date, filter and magnification is useful for the next time to give a closer starting point.

Seeing was still pretty good at the time of this RGB image.

This is my first attempt at WinJupos derotation of RGB images. I only used 3 images, but the definition seems to be improved across the face of the planet. After composing in WinJupos, I still found that I had to do a minor color alignment. Is that the experience of any others out there?

Thanks for looking!

That is such a great image! I could be wrong and probably am but it looks like you got two moons on the planet. You can kind of see it on this last image and even better on the first with what looks like its shadow also on the planet. In both shots it is almost directly above the bigger one on the other dark band.

This last image is one of your very best! You are getting to be a top notch planetary imager. And you don't even live on an island!

Thanks everyone for your generous comments.

Ralph - only one moon shown here. But Jupiter is a stormy planet and spots break out all the time.
