The Shark Nebula

[crimbfighter]

Buuuu-dum.... buuuu-dum.... buu-dum buu-dum buu-dum bu-dum-bu-dum-bu-dum

Last night's target, the Shark Nebula! Located in the constellation Cepheus, this is a large gaseous cloud, shaped by the hot stellar winds from the stars. As a bonus, there is a fairly bright galaxy near the right edge of the image, known simply by its catalog name of UGC 11861. Not a very sexy name...

As an extra bonus, I had a short time before it was dark enough to start shooting my intended target, and the moon was still up, so I got a photo of it.

Phenomenal shots! Your moon shot is super sharp. Love it!

The Shark Nebula is appropriately named; it looks just like one, moving through the ocean. Beautiful.

All that, and a galaxy too? This is really impressive. Beautiful work!

Wonderful shots! I would have named it dragon's head nebula personally...
