As Ha has been used for luminance, the surrounding sky is black, i played with bringing the value to 20 but didnt like it that much and felt it was what was recorded so it stays.
in deference to some of the trends of no stars, they are in abundance and if anything i boosted them slightly. i havent gone down the path of supersaturating the image, i could back off a curve and boost the saturation, but again its all to taste. i have had the monitor calibrated recently but.... who knows if what i see is what you see.
im sure its not perfect, and if you have critique, be sure to explain how to change it so i might learn something.
i found none of the programs i have gave me the colour i wanted so i had to mix and match and blend accordingly. programs used include pixinsight, photoshop, startools.
hopefully the rain will ease soon and we can all get some more data.

Okay then, I'll be the villain
I like your image Clive but a natural palette HII emission neb is predominantly a pinkish-RED, not salmon coloured as yours is. This is a common issue when blending Ha into RGB. There are a few short tutorials on the web that explain the basics of such blending. Note that my critique has nothing to do with "super saturating".
Moreover, natural palette images, if that's what you were intending, are not subject to personal taste IMO. They should approximate reality as expressed in a properly calibrated RGB master.
I can correct yours easily in PS (demonstrated below) but this is sub-optimal because it's better to use original data and avoid the problem altogether (naturally).
