Another unusual open cluster ... My charting software (Megastar v5.0.14) does not have "D2005c DC8" in its database. I first found 'DC 8' in Deep-Sky Planner ( "D2005c DC8" is the grouping of stars just to the east (left) of center. The CDS confirms the identity 'DC 8' as an open cluster, but prefers the usage "D2005c DC8". In 'Deep-Sky Planner', this cluster is identified as OCL  298 / DC 8.

* This object is not listed (as 'D2005c DC8') in "Star Clusters", by Brent Archinal and Steven Hynes. However; at 06h 09m 20s, +31d 13m 30s, there is "Teutsch". The size of 'Teutsch' is listed as 3.5 arc minutes. In 'Comments and Aliases' is noted: "Teutsch: Likely cluster. Condensed group. Located 3.5' SE of bright star HD 41889 (V=7.62, A2) = ADS 4734 A."

See the CDS image/data for this field.

Still looking for objects to image in one or two nights, because of the weather ... Imaged this one through high clouds, except for all but about three or four subs that were clear.
