Description

I think this is my fifth or sixth attempt at this target. It's better than my last, but not close to what I wanted. I think I should have used 15 minute exposures, and secondly, I couldn't HDR the core in no matter what. I tried 30 second subs for the core and those revealed the structure, but I didn't manage to combine it with the whole image (either with layermasking in PS or HDRcomposition in PI). It kind of worked in PS, but the dark area separating the eye from the longer exposure looked silly (I used a gaussian blur for the core mask). Oh well.

Is there a first shock wave visible above the main wave? About the same radius as the first.

Edit B: Included the core in PS. Probably still not the best way to do it.
