Description:
In Taurus, at ~ 3½ degree of Aldebaran. Beautiful cluster whose 8-9 stars are
observed individually. Also, I detect a nebulosity of unresolved star
background, made up forming part of the cluster. A beautiful double star,
composed of HD 30179 and HD 30197, is located in the south of this regrouping.
Inside NGC 1647, I distinguish 3 double stars with averted vision: first is
formed by TYC 1275-689-1 and TYC 1275-1250-1, second is formed by TYC
1275-1110-1 and TYC 1275-723-1 and the third by TYC 1275-461-1 and TYC
1275-851-1. After research, the second double star appears in the WDS and names
AG 311 (Astronomische Gesellschaft catalog).
