Description

Actually I think this looks more like a Stingray with the long tail and strange eyes. But I suppose we already had a Stingray Nebula. (-:

December weather hasn't been great. I started capturing Ha early when the moon was rising. Then it took 10 days before I could revisit with RGB. Having some L would have been nice, but the weather said no.

This is RGB with a red-colored starless Ha screen layer.
