Lovely images, forgive me as I am fairly new to mono but is the time taken on each image very different (in favour of the mono) and also the colour camera a lot less sensitive...would that not have a massive effect on top aswell as the light polluted site?

Indeed, the mono has much more data, but that mainly goes to the noise difference, signal difference in a single sub is also massive ...

I should post that one a green sub compared to green extracted from the OSC

2 "green" subs compared, I extracted the green pixels from the OSC.

even the 10 min sub is no match for the 5min sub from the FSQ/ASI combi, though they have about the same pixel scale

Great post, one again demonstrating you cannot beat a good Signal to Noise ratio.

I managed 5.9 hrs of LRGB from a Bortle 4 location, I couldn’t get any hint of colour in the outer region of the galaxy.

V3: a warmer rendition:

An amazing amount of detail there Yves! I just wonder a bit about the strong yellow. Have not seen that galaxy with such a yellow core before and some of those stars in the lower right corner have a yellow core but white to almost bluish halos around them, which lookss a bit odd to me. Usually, in bright stars the core carrry less colour than the halo.

Advantage of a 20MP camera is that you can crop quite aggressively;

Both Maurice and Olly made a comment on the colours being of ... so I adjusted them ...

I like the warmer rendition with the crop.

I brings it home Yves that sadly there is no match for dark skies.

I agree with @kirkster501. I like the softer option out of all the fabulous images taken.
