Taken over 3 months on either side of the summer solstice...LBN 552 in Cepheus. It was difficult enough to frame it as the dust barely registers in a single shot (10 mins for L). Could have done with a few more hours of L but after finishing the colour yesterday decided to post as is...
Enjoy!

Very nice.
You've done a very fine job capturing that form your location!

I've already liked on Astrobin. I really don't know how you do it from your location, it must be something to do with you having better suited equipment to what I have, and maybe more patience to get all this data. Having a remote obsy probably helps to do that too snatching lots of little bits. Plus platesolving for framing.

Amazingly good from Petts Wood!
I really like the star colour.
Where did the curve come from? is that Pixinsight you used for the white balance?
Well done.
Noel
Thank you Mark, Carole and Noel!
Noel, I use PixInsight exclusively now for calibration and processing. The colour calibration is done using a module within it called Photometric Colour Calibration (PCC). It does a linear fit of my image to the B-V characteristics of stars within it matching photometric catalogues for the area. I end up tweaking further to remove remaining green casts that are unavoidable when imaging from London. The only thing I changed in the PCC was to extend the minimum magnitude of the photometric catalogue from 12 to 15. It examined 800+ stars within the image and produced those plots. The whole process is basically automatic.
