Object: Open cluster CZ 43 Constell: CAS RA: 23h 25.8m Decl: +61° 18' Epoch: 2000 Mag: 8m? (own) Size: 13' Type: III 1 p Observer: Jere Kahanpää Obs. place: Jyväskylä Date/Time: 17./18.9.1993, 02.30 Telescope: N 205/1000 Magn: 133x Filter: Field: 22' NE Lim.mag: 5.5m Background sky: 2-3 Seeing: 2-3 Weather: Some fog and quite cold. OK. Brightness: 2 Alt: 75° Description: A quite poor (20 st) cluster. Stars mostly bright, 11...12 and a few of 10th magnitude. Two eight magn. stars shine on the W and N edges. I would estimate the size to be 6' = only half of the cat. size. Still a nice clustering but not comparable with the nearby Messier 52, which is 20 NNW. The Trumpler type matches the visual appearance very well.
