Good work!
Thanks, it could be a gradient that I didn't remove properly, there is a "wipe" feature in Startools to remove gradients but it requires the variables adjusted to get optimal removal. It was a quick 20 min processing job, will redo. Yep flats would make a difference. I do have the gerd Neumann El panel. Need to use it. And you're right the nr did blur the outer stars a bit.

Thanks Trevor. I look at Mike's image and the hubble image and it's truly incredible. I wonder if anyone would do a 3d render of this.

Thanks Bill. A bit of hdr and contrast kept the core in check. The short subs also helped.

Thanks Geoff. That's exactly why I did it. Was waiting for the trifid to come up and the forecast wasnt looking good for later . So thought I'd give it a crack. Truly enough the clouds rolled in soon after.

Thanks. I was surprised with how easy the colours were cause I always struggle with it with dso's. Perhaps I'll stick to 3min subs for rgb henceforth for dso's
