All minor processing comments but because you like the techo-perfecto feedback yeah, I can see the smoothing (shame after so much exposure - just can't win  ) and Hmmm? the red looks like a slight gradient maybe? Of course the big elliptical is indeed huuuge and there is galactic cirrus and galaxy cluster glow there too  I do see a blue gradient on the left side too though  no biggy to me.
Overall, especially for an itty bitty 4", it is a great result, nice work
BTW that's a lot of Ha data there...did it assist?..or was it just coz you can

Yeah the lots of hours makes for easier processing. You could be right about gradients but I think this is most likely in the lum channel. I was thinking it might be gradient too, but did see some slight brightening on the right and not much on the left in the various channels. I might need to remove some subs from the lum and collect some to replace the those removed. See if that makes a difference.
I think half the problem with the lum needing smoothing is that the aperture just cannot collect the light needed quickly. A larger aperture would certainly make a huge difference.
Not sure if the Ha was worth the effort, but I collected it during the full moon cycle as well as the HH Ha data, so it was clear and thought I would try. I might be a different story with a larger aperture.

Yes definitely on my target list for the RC12. Too late to get to it this season but I will next. I took an image of this with the RC8 quite a few years ago now and it is crap really and the image needs to be replaced with a much more thorough image.

Yeah thought that might be the case. The image out of photoshop is fine, when I made it ready for web I adjusted the gamma and this black point clipped it. I have now replaced the image and that not clipped. Your thoughts?
