| Notes: | This little trio of dark nebulae are among a couple of dozen Barnard
small dark patches that cluster around the Northern half of the great Scutum
Star Cloud. This field is about 2.8 degrees WSW of M
11. B 127 is centered, B 129 is North and East (above and left), and
B 130 is barley noticeable to the Southeast (below left). These descriptions from the on-line Edward Emerson Barnard "A Photographic Atlas of Selected Regions of The Milky Way":

Irregular,
diam. 4 1/2´. Very black in its southeast portion, diffused on
the west side. B 127, 129, and 130 are connected in an irregular
curve, convex to the west (see ibid., p. 7, and Plate IV for an
account of visual observations, and a photograph of this object
and of B 129).
