Jupiter - 1 Dec 2023

[geoflewis]

After missing out on Neptune due to cloud, the skies cleared later on allowing me to take another run at Jupiter as a preamble to trying again for Uranus 5th Moon Miranda, and hoping to capture Uranus ring system. I'm still working through the Uranus data, but have now completed processing of the two 9x1m SER runs on Jupiter in colour and IR.

The seeing was mostly good, so a lot of fine detail has been revealed. My processing continues to develop, with me trying to hold back on the HF wavelets, which I've concluded have given too sharp an image. Hence, for these 2 images I traded some HF wavelets in Astrosurface for LF wavelets, just to bring some of the larger features to the fore, hopefully without over sharpening or creating edges to features. I've also adjusted the colour temperature in Image Analyser to give a slightly warmer look to the colour image.

Thanks to Kostas @Kon for critiquing several versions of the colour image, before I posted it here. As always, I'm interested on any feedback from anyone about what they like / don't like other suggestions, etc., on these images.

As I said offline, this is a superb image and balance between smoothness and details. The best I have seen from UK this winter.

Thanks Kostas, I'm not sure about it being the best, but I agree that it turned out quite nice. Thanks again to your input over how hard to push the processing.

Very nice image. Lots of detail and just the right amount of sharpness.

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.

Great detail again Geof! Personally I prefer your previous images from 25th and I think 11th Nov? They had finer detail with a more natural appearance in my opinion.

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.

Yep that is a bit too much sharpening. The detail is becoming bloated especially on the north pole. If thats grade 3 and the first version is grade 2 I'd go for grade 1 🙂

Sorry to jump in Geof but what format do i put into Winjupos? Is it decimal degrees or other? Thanks.

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

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.

I would disagree+agree with Stuart @Space Cowboy as the softer ones feel like lacking something+something plesing too; the north pole is a lot softer but in the original image you have really nice details without being too much. The softer ones can be more pleasing to the eye. We have discussed this in length on how to have the smooth Damien like images that still have enough details.

Hmmm.....I think its the type of sharpening. The detail in the softer version still looks coarser than  your previous November images.

Its the fineness of detail I'm on about Kostas. Damien's images have such fine detail if we are making a comparison in that regard 🙂

Thanks. I have been using Sharpcap for capture. I will have to have a look at Fire capture. I have just downloaded Winjupos today and I'm watching the tutorials on YouTube. Is the location details in degrees/minutes or decimal? I have watched two videos who say contrasting things. Sorry for the incessant questions but this is a steep learning curve. Much appreciated.

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

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.

You probably want to delete your exact coordinates from a public forum.

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.

Edited December 9, 2023 by geoflewis
corrected longtitude to -ve west +ve east

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

Sorry Geof I was meaning wavelets in the sharpening sense. People talk about Registax, astrosurface or wavesharp but in my view there are so many different combinations of wavelet settings that similar results can be attained from either application.

I really need to get some new data of my own rather than waffling 🥴

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.

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

its a magnificent image, the processing looks very good to me. A nice balance between maintaining a natural looking image and a good level of detail.
