Incredibly faint but very exotic! Located in the southern Puppis constellation, this cometary globule is more shaped like a cosmic monster about to devour the galaxy PCG 21338, and reminds me of a Dune Sand Worm! This is 18.5 hours with 15 min sub frames used. Processed in Pixinsight and taken with ASI 533 MC PRO with ASKAR V @600mm F7.5. Needs about another 100 hours of data lol (thanks Nick A for his original post!)
