Greetings,
I processed data for NGC 457, the Owl Cluster (or some prefer the ET Cluster). Last time I visited this in an imaging session was 2003. I don't think it has changed much since then ( :

Good job taming the bright star in that field, Jim.
The colors look good, too.

Well, not exactly lines... but the best way to think of it is to mentally rotate the image 180 degrees. The Owl's head (as presented) is at the bottom. The two bright stars are the eyes. The wings extend out to the sides and the body and tail are the brighter blue stars of the cluster. Yeah, the more I think of it, it does take a bit of a stretch of the imagination.

Cool pic, Jim! You definitely caught its "Owliness", or, for a later generation, "E.T.-ness". wink

Nice one Jim! Those "eyes" are pretty cool.
