Thanks Rick, I like the stars in this one a lot better, but can't reproduce the depth of the nebula I achieved last time without blowing out the core of the brighter stars. Never the less I am reasonably happy with it.

Thanks Richard, glad you like it. I'm not sure why but I actually really struggled this time getting the panels to match in illumination so that when I integrated them you couldn't see the join. Practice makes perfect, or so they say. Sorry I forgot to list the ISO, this is ISO800, I'll add that detail to the first post. Noise reduction I used my usual routine which consists of making a synthetic luminance channel, and also extracting the RGB channels. I use a luminance mask on each channel, and then then run a very subdued ATWT on all four channels. Normally only the first 2 wavelets, sometimes three. The actual settings for each change depending on the noise that's in each channel. Like I said I go very very easy on it because otherwise you end up with a blob at the end. After that I do an LRGB recombine. That's the only noise reduction I do throughout the whole processing, if I get to the end and I am not happy I come back change the settings and redo everything after that. I am still experimenting with the TVG denoise that you pointed me towards, but I haven't found the optimum settings as yet.
