Hi All, have continued to process avis from Wed morning. Amazingly constant results with no standouts. I did a ppm centre on one batch and have run it with 3 x MAP point alignment in Registax 4 to produce that here.
Very good capture of the Crepe ring (C). Did you use a standard gamma of 1.0?
I also find your processing method interesting. Usually significantly different processing of the RGB channels leads to spurious color. But I have found LR decon on the different color channels sometimes requires a different radius. When MaxEnt works it seems better, but more often than not it does not converge (at least with MaximDL which will allow deconvolution on color images).

Hi Glenn, I set gamma at either 1.1 or 1.2. Usually I do the same processing technique for each colour channel for the reason you mention, or at most change the radius slightly. In this case the blue channel was a Lot fuzzier than red and green so I just gave the latter two a very mild unsharp mask while applying LR to sharpen up the blue channel.
That is a beautiful image of Saturn in spite of the low altitude and the less than optimal seeing in Brisbane at the moment. With such quality images as this, right now, it looks like there is only room for one C9.25 in Brissie so I’ll be happy to keep my ‘scope inside, have a morning lie in and appreciate Saturn through your wonderful images!
Looking forward to some more of your razor sharp saturns from days of yor..
