Published comments

E.E. Barnard (1919)

Barnard (Astrophysical Journal, January 1919) writes in his 'Notes on the Catalogue' that "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 (mag 8.8) which is nebulous. This is apparently a large dark nebula, the brighter part of which forms the star +69°1231." He also notes that there is a "bright nebula in north part." Barnard photographed the nebula, which was "conspicuous", with the Willard lens at Lick Observatory on 24 September 1895 with a 5 hour exposure. It is also shown on a later photograph made with the Bruce telescope on 20 July 1904, which needed an exposure of 3 hours 1 minute.

E.E. Barnard (1927) - ADC catalogue VII/220A

Note (supplied by Bill Gray, Project Pluto): Large; diam. 1 degree; bright nebula in N part. 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.
