Searching for another (see Waterloo 1) 'one night' object to image, and came across the open cluster "Ruprecht 148" in 'Deep Sky Planner' (v5.1.3). Hard to tell anything is there; Center star is IRAS 04429+4437.

According to "Star Clusters", by Brent Archinal and Steven Hynes, the size of this open cluster is listed as 4.0 arc minutes. Skiff calls it a "sparse group". 'Star Clusters' position is the same as my charting software (Megastar v5.0.14), but the CDS has a slightly different position: see CDS image/data.
