I reckon they're great, Robert! Heaps of detail, just a little burnt out in the core. I'd love to see you reduce the gamma to 0.8 or 0.7 in astraimage on the final combined result. I reduce mine to 0.6 after capturing with 50% gamma. The last 2 also look like they could use a little shift in the X axis with your red/blue.

The onion rings you're describing in the other thread, do you mean the right edge of the far left image? In my experience, that's not onion rings.. that's over-sharpening, like getting an "encke division" on a Saturn image from over-sharpening. I find it happens on my images if I'm too aggressive with the LR deconvolution.

Here's 2 examples of what I mean by the gamma - I used your far left image and your far right image, and took them into photoshop. I used the circle marquee tool to select the middle 80% of the image (with a 35px feather), and I used a new curves layer to reduce the exposure in the middle. You can achieve the same effect in AstraImage as I described above by reducing the gamma after recombining.

Hope you don't mind me playing. Great images!
