Man a lot of exposure there Brett

well done, having an observatory helps there huh?

...although I have an observatory but I simply don't have the patience to do 40hrs on an object, Mr Lazy

.
I think it looks pretty good with the outer shock fronts starting to show nicely, the trick is getting the OIII spokes (which you have showcased nicely there) to show
as well as the famous inner Ha globulated smoke columns and detail in the main ring, this is very tricky to pull off and very few have managed it.
Nice work
Mike
