For me a big downside of very fast capture speeds is the much larger SER files that creates. The only time I've felt that super fast speeds worked was with Mars last year in poor seeing and even then I'd say the jury was still out. With the much smaller ROI on Mars, it wasn't the issue that I get the huge file sizes from the much bigger Jupiter.

Thanks Pete

So very true....!!

Believe me, I know that feeling. The 'previous' version as you called it is smoother, but I think too soft - it's the fight we continuously seem to have.

Very nice image Pete, smooth with plenty of detail coming through.

Very nicely done, colour balance is good. Either the seeing was very poor (you hinted at that), or you didn't quite get tight focus.

I've PM you a few TIFFs

Thanks Pete, that's what I keep striving for....

Happy to share any of my raw stacks, if you want to play with the data....

I save my wavelet settings in Registax and Astrosurface, so really no, or very little difference in that part of my processing. What I did differently with Friday's image was different saturation/vibrance and adjusted the colour temp in IA from the default 6550K to 6300K to 'warm up' the image. Maybe the stronger / warmer colours give a different appearance to sharpness, but of course also diffeent seeing conditions, so no 2 images ever process the same. Nevertheless, it's very helpful to have yours and others eyes on the case; your feedback is very much appreciated, thank you.

Yeah, I thought that after posting, but it's not that precise....

Great, so for longtitude use -ve numbers if west of Greenwich, +ve numbers if east of Greenwich. For latitude, northern hemisphere is +ve, southern hemisphere id -ve.

Do you mean this section? It is degrees and minutes, but honestly in my experience it has little bearing on the processing. If it's something else, please could you share a screenshot.

No sharpening per se, just a different mix of wavelets. I almost never use any sharpening tools on my planetary images.

There is a trade off between capture speed and signal. I've had discussion about this with a few different folks, a couple of who are top planetary imagers in Australia, Anthony Wesley and Niall MacNeill, both of whom prefer signal over speed, though their seeing conditions are usually better than we experience in the UK. You only need enough speed to 'freeze' the seeing. Take a look at the discussion thread on this image of mine in Astrobin, where Niall shares the analysis that he did and observations about Anthony Wesley's (nickname Bird) methodology..... https://www.astrobin.com/0znu04/ That said, as @Kon mentioned, after experimenting with 5ms, 8ms, 10ms and 13ms, I too have settled on 10ms as my goto standard for Jupiter and Saturn. I also shoot for a fairly high histogram of 85%, which seems to help render a better colour balance in post processing.

Sorry, I'm not understanding the question? Where are you looking to enter something? I save my SERS in FireCapture with WinJupos ready format file names, so I just load them into Image Measurement, fit them to the outline frame overlay and WinJupos does it's thing.

Thanks Stuart, oh so I thought you were asking for sharper detail. Here are my other 2 version.....

Thanks Stuart, the images from 25 Nov and the better one from 11 Nov both had the GRS showing which is always pleasing, so makes them look good, but you may be right. Of course seeing is variable and possible the seeing on 1 Dec wasn't quite as good. I did produce a sharper version, which possibly shows more detail, but it just looked too harsh, but here it is fyi... I will be interest to have your opinion please.

Ok, yrs that's been there for a couple of months at least. It was there for my 1st look at the GRS this apparition in Sept, but has continued to develop with its interation with the GRS rotation. Here's a few of my images fyi...

Well yes, IR is mono, but I'm using the very IR sensitive colour camera ASI462MC.

Nicely done Peter. Which feature beside the GRS are you referring to. Oval BA is a redish feature just below and to the right of the GRS which seems to be reforming after it's encounter with the GRS a few weeks ago.

Excellent animation, very consitent processing with good details showing.

Very nice image. I use the same capture settings and duration for IR as I do for colour and process them almost identically (other than colour adjustments of course).

Thanks Roy, yes, low elevation and getting smaller as it recedes from Earth in their respective orbits.

Thanks Roy, I really appreciate the feedback as I've been struggling to get the processing right, though I think that I'm getting close now.
