well thats very good!

[Carole]

Looking even better.

Excellent job. Even a bit of detail on the moon.

Here's the final attempt - 4000 frames out of 5000 (5.5 minutes):



Compared with the previous version (1500 frames):



And the original (500 frames) which needs 180 degree rotation:




The interesting thing is that Jupiter rotates quite a lot in 5 minutes (8 pixels at the equator at this scale) but AutoStakkert2 has clearly coped incredibly well and lined up all the features.  The AutoStakkert site has a link to an article ( http://www.planetary-astronomy-and-imaging.com/en/maximum-video-time-jupiter/ ) suggesting that Winjupos is not needed a lot of the time (I've never used it).

You may be right Duncan, that I've caught some detail on the moon but I'm a bit cautious in claiming that.

Latest version looks really good.

Yes - you can have a copy of DCON - in fact I'm sure you took a copy at a DSC when I demonstrated it.  I'll put together a tutorial because it has a few quirks and foibles.  But it allows you to do a few things I've never seen in any other software.

Here it is with a brief tutorial included on the functionality required for deconvolving a planetary image (with example images including the 17 March Jupiter) - also works really well for deep sky images as a final stage.

Right click the above link and do a "Save As".  Make a folder on you drive and extract the contents of the zip file there.  Take a look at the readme.txt and the tutorial document.

If you try it, let me know how you get on - especially if you get better results than Registax.

my computer advises me not to download your file Mark,as it can be dangerous! not had that warning before

What an excellent capture of Jupiter, it sure does look like a small dust mote on that moon though

Definitely looks like detail on the moon on my monitor - very nice shot - How does it compare with your previous attempts - I seem to remember you having some great captures before...

I think it's my best ever.  My previous best was this one, taken when Jupiter had a band missing:


AutoStakkert!2 has a lot to do with it - I'll try running that old data through AS!2

Interesting.  Maybe because it's a zip file or maybe because it's a zip file with an executable in it.  In general it's not a good idea to download stuff unless you are sure of exactly what it is and you trust the author.

The improvement is palpable. It's amazing what improvements there have been in the processing that enable Joe Bloggs to get amazing planetary images. It's a bit magical to see a defined sharp image appear from a blurry video

If it's like Win10/Chrome it's because 'this file is not often downloaded' or some such as twaddle based on the lists they compile of popular downloads. So anything astronomical will fail this check. Ignore it.

[MarkS]

Interesting that Ganymede in my older picture is so much brighter than Callisto in my recent one, even though they are not that much different in size.  So I looked it up:  Ganymede has an albedo of 43% whilst Callisto is 20%.  Now I know!

Really nice Mark,  I have dug my colour SPC webcam out to see what I could get with it, not sure on the quality

[JohnP]

Fay - you got rid of your high speed B&W camera?

Take a look at the incredible improvement Damian Peach achieved using AutoStakkert and WinJupos

Interesting that he can now use up to 15 minutes of Jupiter data in one image.  I must give that a try.  The great thing about so much data is that the signal to noise level reaches very high levels and allows the deconvolution to be pushed to extreme limits in terms of the maximum amplification that can be applied to data in the wavenumber (Fourier) domain.

I'm sure there's more detail I can extract from my recent image - I just need to process 12000 frames instead of 4000
