Hi Peter, nice image & a great field!
Regarding Mike’s mysterious object mentionsed above, I thought that was SH2-54? 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 bottom of frame in this image I took two years ago.-
