Given it's nearly the anniversary of the 2023 TSE, I've been digging through my Exmouth Eclipse data, looking at new ways to process the data.

So many filter routines unfortunately add a false "bas-relief" effect to the corona plus trash the
brightness variation from inner to outer Corona.

Using Pixinsight's many tools, plus Druckmuller's NAFE routine I think I may have managed my goal....
well... for the inner corona at least....but so much more to do in extending out to a few solar radii.

An early "new" processing result is here (http://www.atscope.com.au/BRO/gallery644.html)

Hope you enjoy the view.

Fabulous. Must have been quite an experience.

Ta Greg....it was a heck of a drive that's for sure!

Exmouth was the "prettiest" TSE I've witness to date.

The image processing required is computationally intensive. Each fame needs about 5 minutes on my rather quick Threadripper PC just for the NAFE routine. This image was 8 frames. I have another 242 to go...

That said I expect with a few dozen frames combined that the background noise will evaporate allowing me to tease out some more detail sans artifacts.

We shall see!

Absolutely incredible work Peter. Such a huge part of this is actually knowing how to handle the mountains of data acquired in those few short minutes, and the skill to make it into a coherent image! I look forward to what you can produce once the rest is processed

Very, very nice inner corona details, Peter.

Eclipse image processing sure is demanding (and I'm sure the techniques have progressed significantly since I last tried them in 2017).
