The Leaping Puma's size is approx. 7'30" min.

After stacking the Rosette Nebula's frames, my son Ben (13) and I enjoyed the new image and zoomed in on various areas, and there it was:
The puma that was lurking in the shadows just leaped at our faces...and right then and there, we've given it its name:
"The Leaping Puma Nebula"

The Leaping Puma's name was warmly embraced by many astrophotographers.
I'll list some of the links here below, and ask forgiveness from all those lovely images that I have missed:
