Here's my re-processed version of M42 and the running man from Wiruna.
Taken with QHY8 gain0 offset 60 at prime focus on Celestron 130 SLT. Guided with PHD on ED80/G11. Captured in Nebulosity 2.
Dark/Bias subtracted, flat applied in CCD Stack. Composite of 5x900s, 10x300s, 10x60s and 5x15s. Bit of noise reduction and compositing work in photoshop, mainly masks to reveal the different layers of brightness then shadow/highlight filter to accentuate the colors and tone down further the brightest parts. I found it very difficult to balance the colors and the difference in illumination from the core to the edges. Let me know what you think. Comments and processing tips most welcome. Slight amount of field rotation due to polar alignment on longer subs so don't look on the edges
Thanks for all the comments guys. I still have more data to add to it in particular around the whole outside of the two DSOs. There's a lot of dark brown stuff going on in there but I still need to process it.

Thanks Mike. Yeah I'm not sure. It also has a rainbow on the spikes. Could it be a double reflection somewhere? Maybe they're not aligned because of some misalignment? I'm sure one of the experts on the forum will pitch in.
Personally I think it might be field rotation between the different exposures.
A fantastic result Marc. You have done a great job with blending the different layers together. Lots of detail and very nice colour.
I had a go myself at imaging M42 using different expsoures and I found it quite difficult to get the right balance between getting the correct colour and trying to bring out the detail in the different layers. Looking at your image, I think you have done a great job with it.
That's a great result Marc, blending the different exposures is not easy and you've done a good job. You've got some great data there. I'm looking forward to seeing the result when you add the extra data for the outer detail and the 'dark brown stuff'. The QHY8 is a winner.

Very well done.
Thanks Matt. Yeah tuning down the bright parts makes them grey. It's not as easy as I first thought blending the all thing together. Glad you like it.

Thanks Rob. I'm looking forward to see yours when you post it. Should be much closer to the core.

Thanks Rob. It's one of my favourite targets. It's the first good picture I got of it.

Well done !
Thanks Andrew. Stars are still a bit harsh to my liking but next version with more data should be nicer. I missed that when I used the shadow/highlight tool.
Here's my final version with all the data included.
I added 10x300s + 10x600s . Stars and colours are softer, overall picture is not as harsh. I like this one much better.
the double spikes could be due to the spider vanes being ever so slightly bent, i had this happen to mine a while back, it takes only the tiniest amount to do it.
if you had shot it over 2 nights i would suspect the camera rotated slightly between the exposures.
The extra data has really smoothed out the image out without loosing any detail.
Very nice.

Thanks guys. I like it much better when it's smooth too. Glad you like it.

Glad you like it. My spider vanes are not exactly square and they're a bit twisted and bent too. Makes sense. I never thought about that one. I'll have to look into it. Thanks Clive.
