CGCG 074-058: extremely faint, round, just 10" diameter. A mag 14.5 star is 0.8' N.

CGCG 074-062: extremely faint and small, visible intermittently with averted vision.

Wilhelm Tempel discovered NGC 5423 = T VIII-7 on 25 Apr 1883 while observing the NGC 5416 group. In the narrative portion of list VI he mentions discovering two nebula about 5 or 6' away from each other and about 40s and 45s of RA following and several arc minutes south of NGC 5416. NGC 5423 = UGC 8952 and NGC 5431 = CGCG 074-065 match this description. He micrometric position in table VIII-7 is accurate.

400/500mm - 17.5" (6/4/94): fairly faint, small, round, 40" diameter, sharp concentration with a very small bright core and occasional stellar nucleus surrounded by a fainter halo. At first glance, it appeared that there were a pair of mag 14.5 stars 1.6' W and 1.8' WNW but on closer scrutiny the "star" due west was seen as a small galaxy MCG +02-36-016 = CGCG 074-058. An even fainter companion MCG +02-36-018 = CGCG 074-062 is 1.5' ENE. Also, NGC 5424 is 5.0' NNE and NGC 5431 is 4.7' ENE. Located in the center of the NGC 5416 cluster.
