Observing Notes

E.E. Barnard
25cm f/5 Astrograph

Irregular partially vacant region, diam 25'. This is the center of an irregular, partially vacant region 25' in diameter. It is suggestive of the presence of a dark or faint nebulosity, as there are several small darker spots in it. It lies 40' northwest of Nova Cygni of 1876, and involves the stars BD+42°4177 (5m.2), +42°4172 (8m.4), and 42°4164 (7m.7). It is somewhat extended east and west. A very long exposure on this region would doubtless be interesting."
