Another unusual open cluster (see DC8) ... My charting software (Megastar v5.0.14) does not have "Dutra Bica 84" in its database. I first found 'Duta-Bica 84' in Deep-Sky Planner ( It is the grouping of stars centered. The CDS confirms the identity of 'Dutra Bica 84' as an open cluster. In 'Deep-Sky Planner', this cluster is identified as OCL  299 / Dutra-Bica 84; However, the CDS lists NGC 146 as 'OCL 299', and "Star Clusters", by Brent Archinal and Steven Hynes does not identify OCL 299 as an alias of '[DB01] 26'.

There are several dark nebula in this field, some right around the IR cluster. The most obvious is DOBASHI 4554, which I caught mostt of at the western edge (right) of my field. See marked image ...

* This object is not listed (as 'Dutra Bica 84') in "Star Clusters", by Brent Archinal and Steven Hynes. However; at 06h 09m 28s, +24d 55m 00s, there is "[DB01] 26". The size of '[DB01] 26' is listed as 4.0 arc minutes. In 'Comments and Aliases' is noted: "Infrared Cluster. [DB01]: Resolved stellar group related to IRAS 06063+2456, partly optical."

See the CDS image/data for this field.

Still looking for objects to image in one or two nights (and now, keeping away from the brightening moon), because of the weather ... Imaged this one through some high clouds, and both nights had fair poor seeing (something I'm seeing a lot of this winter).
