| Notes: | Saw this field imaged online by Antonia F Sanchez ... here is description from E. E. Barnard's "Photographic Atlas of Selects Regions of The Milky Way" - 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 (5.2 mag), +42°4172 (8.4 mag), and 42°4164 (7.7 mag). It is somewhat extended east and west. A very long exposure on this region would doubtless be interesting.. |
