Reprocessed Saturn 26/05/15. Hexagon 'almost' there...@19 Degrees Elevation!

[PJW66]

I've just tried a few things to improve my initial processing attempts such as larger alignment points,no drizzle,and less aggressive wavelets and it seems to have paid off. This run was originally @  20gb 31800 frame sequence. In PIPP I carried out a quality estimation using 24% of the frames and also enabled quality weighting which,if i understand it correctly ,adds the best frames back into the avi (?), Anyway, it seems to have improved the s/n noticeably,as well as colour saturation.Used 100 sized alignment points in AS!2, and stacked 100% of the PIPP frames. Once loaded into R6,did an auto RGB align, and mild default wavelets using the bottom 3 sliders. Loaded the TIFF into AstraImage3 and carried out max entropy deconvolution with gaussian point-spread @ 1.4,iterations 7.Carried this out twice,then adjusted the gamma from 1.0 to 0.9. Loaded into PS Elements, used levels to darken the background,and increased the saturation of yellow,red,and green slightly.Carried out a despeckle which took the edge off the graininess without blurring too much.  Finally removed colour cast by clicking the dropper onto the B Ring,which became nice and white.
A big thanks to Stuart (Space Cowboy) for the advice.

You are certainly getting the maximum detail out for this low elevation Phil!

Personally I would maybe back off a little on the sharpening to produce a smoother image but its all personal taste whether we go for maximum detail or a more natural look.

Colour noise reduction is worth a look in image analyser as it will clean up any false colour ie blue in the rings. If you've not tried analyser here is a link

Very nicely done.

[PJW66]

Thanks for that Stuart!

Thanks for the kind words Pete!

Great effort Phil and thanks for including a very detailed account of the processing which I am sure we all find very helpful

[PJW66]

Thankyou very much Alan.
