This is a combo of M83 data from a CDK17 (1 hour of luminance Microline16 camera) and about 18 hours of luminance from ASI183mm and AP Honders F3.8.
So its mostly the RHA here.
I am happy that this little 183mm works on the Honders as the small pixels could have meant it doesn't work well with it. I'll have to experiment more with 2x2 binning as I don't think I would lose hardly any resolution but would gain a bit in signal to noise ratio.
M83 HaLRGB. 60 1180 150 250 240 minutes a total of 31 hours and 10mins
The data actually showed the extended halo and the arm that branches off the main spiral but at a cost of spoiling the rest of the image so I didn't try to get that in the final image.
Thanks Andy. I was wanting to see how well this ASI183mm could do galaxies and it does pretty well. But its the CDK data that adds the fine detail.

Thanks Rodney. I did have several versions and I did prefer this amount of colour. Its often a challenge how much colour to "give" these objects.

Perhaps a bit too much noise reduction The detail looks a tad soft to me - especially near the core.
A great image regardless though Greg! Nicely done!
Thanks Marcus. Good tip. I just did a quick repro, same link and sharpened it up quite a bit without highlighting noise. I think this is as sharp as I can get it. The CDK data, as you would expect, has more fine detail in it than the RHA 305.

Thanks Mike. I think that could be a formula, RHA data for the bulk of it and some nice sharp detailed CDK17 luminance data on top. The latest version is a lot sharper, same links.
