Description

The nickname given to this nebula is The Phantom of the Opera, although I have to admit that for me it does not have a defined shape, although this is normal with this type of object since our brain interprets the images differently in each case.
What I like the most about this image is the large field of stars that can be observed, as Dave Bowman would say "my God is full of stars", without a doubt a gift for the eyes.
