SH2-173
The Phantom of the Opera Nebula
Starting Halloween early with this eerie 77 light year wide face looking down upon us from 8800 light years away in space! My, that is spooky!
Classified as SH2-173, this is an emission nebula in the constellation of Cassiopeia. It is made of ionized hydrogen gas which give it the red coloring. This one was also super dim so I have 22.5 hours of acquisition time to produce this image.
