Thank you Mike and Trish. It is a bit of a challenge to simultaneously show bright and dark regions while not making this DSO look flat. Combining Ha and OIII has improved the SNR across the image by about 5-7% (as opposed to only Ha), so noise reduction was just cosmetic.

I guess 20 x the integration time and a complete change in setup may make a difference too!
On that theme - I wonder what you would say were the biggest factors in the difference between these two images? Knowledge? Integration time? A particular piece of gear, or a trick that made it all fall into place for you?

Thank you Markus.
There are many many aspects that can be improved, but overall I hope the image is not too bad for this aperture.
As for the difference between the two images, I think it is a combination of lots of things, but better data processing is probably one of the key elements. Then would be integration time+more capable equipment+a darker site.
I look forward to finishing this image, probably in a few weeks as the weather has worsened and the moon is starting to shine splendidly yet again.
