Type: dark nebula
Mag: –
Size: 4′
PA: ?
Barnard (Astrophysical Journal, January 1919) writes in his 'Notes on the Catalogue' that this dark nebula is "Apparently a real object, the south of several dark markings covering a space 45' in diameter. They form a notched outline to the northwest side of the large star-cloud in Scutum."
Note (supplied by Bill Gray, Project Pluto): Irregular; diam. 4'; one small star in it
This nebula can be found easily by locating the open cluster NGC 6683. In a 15.5-inch reflector with an eyepiece delivering a one degree field of view, the star field to the east of the cluster is well populated, as can be seen when sweeping the area. Suddenly, just west of the cluster, the starfield disappears, and you strike a suspiciously barren patch, with only a dozen of so stars in its boundaries. It is easy to pick out and trace the outline of the dark nebula because of the sudden transition from star field to void.
1997 July 6, Sunday, 21:00 - 23:00 Jonkershoek. 11x80's tripod-mounted. An obvious but ill-defined, roughly teardrop-shaped dark nebula, in a hazy field.
1997 July 8, Tuesday, 20:55 - 23:30 Jonkershoek. 11x80's tripod-mounted. Teardrop shaped muddy patch, especially distinct on the eastern side against the starry milky way sky. Has a long tendril snaking down to Beta Scu.
