Great shot of this magnificent nebula Pete, well done
Superb colouring too. Along with the nearby and slightly closer (5500Lyrs vs 8800Lyrs) Cats Paw, there is very little colour variation to be had within the nebula, so while
some subtle colour variation can be enhanced in each nebula, because of their great distance, in the plane of the Milky Way and the resulting heavy dust extinction, both are probably most accurately displayed as essentially mostly red/orange, like you have here
This is my favourite rendering of it, done with the Dark Energy Camera on the 4-meter Blanco Telescope...looks pretty similar to yours actually
..great to zoom right in on too!
