As usual Mike, plenty to love about viewing this image mate, grand and with beautiful colours
Heck you are loving these 1hr subs too huh?.. very cool... buuut I do agree with Rick, actually I have noticed the same effect in some of your other recent work but it wasn't quite as noticable and so I didn't pass comment. Wavelets and decon can kill an image I recon creating what I call psuedo-detail that looks kinda like turning all the detail shapes into point sources and it is often very noticable. If you get rid of this effect this NGC 253 should be an incredible image and I hope you do as I would love to see it
