Thanks guys for the comments and discussion about the colour. I have done a reduction by 30% on the blue in the galaxy. It's now less fluro I think.

Stars are Uber crisp with excellent profiles...and the myriad of faint fuzzies in the surrounding field are very cool.
I'm guessing the seeing was kind during the data run...a testimony to great skies and no hill required.

Nice one
Yeah seeing is often good on the Murray plains, it helps with the sharpness of the data. Using NINA has also improved the results too. The focusing is better than Focusmax I think and after using Maxim for guiding for years I am now using PHD2 for guiding. From empirical evidence it appears that guiding is much better overall. The change has provided positive results.

Yes the halo of any galaxy is often hard to capture but dark skies make for an easy capture of it. The hard part from then on is retaining it in the processing. I think it is easy just to push the contrast a bit too much and that can kill the halo that might be present on any galaxy. My last attempt at this I did not show the halo all that well. Pushing the contrast on that particular image would have reduced the halo visible. Processing is always a learning exercise.
