M51 - Just got back into astro processing

Hey all

I sold all my gear ten years ago but recently I got the itch again, however I don't have the inclination to buy all the equipment again and get frustrated capturing images.

So I decided to download some data and get the trial of PixInsight, to dip my toes back in the water. If things go well I may get into an astro imaging group for my data needs.

So this my attempt at some high quality data. I've processed this image about 4 times now, with this being the best version so far. Having only been using PixInsight for a few weeks, I've remembered how hard processing actually is. Although each attempt is getting better, thanks to learning and trying a few more processes.

So anyway this is data collected by Martin Pugh:

Capture Details:

Apogee U16M
Planewave CDK 17
Sierra Remote Observatories

L 600s x 39
R 900s x 13
G 900s x 14
B 900s x 21
Ha 1200s x 32

SBIG STXL11002 with AO-X
Planewave CDK 17
Heaven’s Mirror Observatory

L 900s x 47

Total time : 41 hours

Here is Martin's processing of the data, which is handy to give me something to aim for:

And here is my attempt:

That is a massive pool of data in this image.

Well done on your rendition, closely following Martin's reference image.  I am splitting hairs but I am not so sure about the blue cast to the spiral arms, personally speaking.  I like to see a bit more gold in them as in this version:
