The Black Hole Nebula - LDN 323

Nestled within the Small Sagittarius Star Cloud, the Black Hole Nebula—formally known as Barnard 92 or LDN 323—appears as a haunting void in an otherwise star-rich field. This dark nebula, discovered by Edward Emerson Barnard in 1913, earned its nickname from its striking resemblance to a cosmic abyss, though it is not a black hole in the astrophysical sense. With an opacity rating of 6—the darkest on Barnard’s scale—it obscures background starlight with remarkable density, creating the illusion of a celestial shadow cast across the Milky Way.

Since I only collected 26 subs and limited the exposure to 120 sec (moon near full) I did not get as much of the rich star field behind B92 that I would have liked.
