CED 90 SHO CHI-1
Cederblad 90, also known as Gum 3, is located in the constellation Canis Major and is located at the tip of the right wing of the Seagull Nebula. I looked through numerous images, of this object, and could not figure out if the blue object at the lower left 7:00 position is a reflection artifact or a planetary nebula.
Anyway, hope ya like it!
