Like a soaring eagle rising up to an egg in it's nest, here we have the famous M16 Eagle, soaring up past open cluster NGC 6604 towards Sh2-54 top right.
The bright nebula within is Gum-85. The ring around it is Gum-84.
Together, they are called the "nested egg" nebula.
The cluster below is NGC6604. M16 is of course bottom of frame.

It's taken almost two months to enjoy 2-3 clear nights over Melbourne.
This has been been the wettest, cloudiest winter I can remember
Not too many NB images of this region around, (actually I couldn't find any!).
I was hoping to find another to compare to as there's not much O3 present around SH2-54 in my data.
Anyway, as always C&C welcome
