It really extends in a more or less broken form for about 6 degrees. There is a wide region extending south of it for a couple of degrees, nearly to the star BD +53 750 (magnitude 5.0) whose position is degrees, nearly to the star BD +53 750 (magnitude 5.0) whose position is 4h6m58s, N 53 18' (1875.0). To the east it breaks up into more or less separate spots, somewhat resembling those at the east end of the great lane from Rho Ophiuchi, but unlike that lane it does not originate in a larger vacant space or a nebula. Its borders are not so definite as the Rho Ophiuchi lane. It is approximately bounded by the coordinates 3h58m, N54.7 and 4h20m, N54.8.

One of the finest examples of a dark object seen against the ordinary sky and away from the Milky Way. The background on which the stars shine is uniform over the entire plate. The object is in a region somewhat larger than itself, where there are relatively few stars, and is black by contrast with the sky alone. It clearly shows the presence of a feeble uniform luminosity in space which, from the appearance of similar objects in widely different parts of the sky, leads to the belief that this feeble illumination of distant space is universal. If this object were seen against the star clouds of the Milky Way it would appear strikingly black.

Barnard Note: Large dark area with few stars. There is a nebulous border, .5 degree wide, to the semi-vacant region extending 1 degree east and north from BD +12 803 (magnitude 7.0). Apparently this nebulous border extends many degrees east in a very diffused manner. There is a narrow dark lane extending south from the semi-vacant region, running close west of BD +12 803 to a point nearly 1 degree south of BD +12 801 (mag 6.9). There is a small fan-shaped nebula close north of a small star in the position 5h24m30s, +12 3.9' (1875.0). A small strip of nebulosity extends 5' southwest from this star. These two nebulae are probably the brighter parts of a large obscure nebulosity.

It is a relatively gas empty space.  Per Olano (2001) it is associated with a break in the Olano 2 kpc supercloud molecular ring. There are two theories concerning its cause.  Per Olano (2001) it represents the track a proto-supercloud the evolved into the Orion-Cygnus Arm. The supercloud scoured that portion of the galactic disk of gas and dust before it struck a gravity wave and began star-formation.  Grenier (2004) asserts it is the track of a high-velocity cloud that struck the pre-existing proto-supercloud, initiating the formation of Gould's Belt.

This is the middle of the main part of the great vacant lane that runs east from the region of Rho Ophiuchi. It is about 32' wide and has its beginning in a vacant area in which is the star 22 Scorpii (CD -24 12695, magnitude 5.5). It runs slightly northeast to about 16h40m, -23 40' (1875.0). From this point it extends in a broken chain of dark spots to a little south of B 63. Its total length is therefore about 10 degrees.

This is a large dark spot, extended north and south, 62' in its largest diameter. In its upper part is the star BD +69 1231 (magnitude 8.8), which is nebulous. This is apparently a large dark nebula, the brighter part of which forms the star +69 1231. In Monthly Notices, 69 (1908MNRAS..69..117W), Dr. Max Wolf gives a photograph of the nebula, stating that the object was discovered by Dr.Kopff at Heidelberg on October 12, 1908. It is conspicuous on a photograph of mine made with the Willard lens at the Lick Observatory, September 24, 1895, with 5h0m exposure. It is also shown on a photograph of mine made with the Bruce telescope, July 20, 1904, with an exposure of 3h1m. By inadvertence reference to this object was omitted in Lick Observatory Publications, 11, where it is cut out by the matting in Plate 83.
