Very nice image, I also like the contrast between the dusty region with few
stars and the vrowded starfield in the other half of the image.

Another that's on my redo list. At the time I imaged it (and several
others) I had a port plug fall out letting in light from the LED on my
RoboFocus unit. Why they put a super bright LED on that I'll never
understand. It is now covered by electrical tape! The plug is also
taped on so it can't fall out again either. Dealing with that red light
cost me a lot of background which I had to set to black to hide all the
problems. Now I can deal with gradients better so a reprocess might
help but it really needs a redo.

Don't think I ever posted it so here's my close-up version. You got a
lot more of the surrounding cloud with your larger FOV than I did.
