Good to see you Greg being very productive and creative recently, with several great images
Colours look promising, higher resolution image will allow to appreciate finer details. I started working on the same target in January but did not get a chance to complete the photo. Maybe next year
Quick question, around some of the brighter stars, is it a diffraction ring or processing artefact?
They look like diffraction rings but I don't think I've ever seen them in a Ha image before

Very cool object, Greg! Star shapes are a little spiky? I would have been tempted to brighten up the red areas some more but your subtle approach is nice.
The Ha description says it was 10 x 10 mins. Was the time on Oiii and Sii similar?

Perhaps a few of the stars are. Are you referring to the colour image or the Ha? I corrected a lot of that. This was from the earlier time before I had the tracking issue fully sorted so some stars were a bit off. Still that takes pixel peeping to notice as I thought I did a pretty good job of sorting that, perhaps I missed a couple? The Ha was processed as a stand alone image. The Ha downloads really stood out. Yes O3 and S11 are 70 and 80 minutes repectively. Pretty solid narrowband data for such low exposure time I thought.
Greg.

The stars in the Ha look OK. It was the colour image where I noticed some slight oddness. It's only a minor nit and you do need to look closely. The big orange stars at the top of the FOV show it most clearly.

This is a really interesting object. I like your colour palette (very similar to mine ). It's on my list for the bigger scope if I can ever get a straight run at it. Even if the seeing was not good, you have a pretty reasonable view of the object.
