NGC 4603
24" (4/12/08 - Magellan Observatory, Australia): at 200x appeared very bright, very large, elongated 2:1 SSW-NNE, 3'x1.5', broad concentration though the brightest portion seems offset towards the a star embedded just west of of the core. A second superimposed star is near the southwest end. NGC 4601 lies 5.3' NNW and NGC 4603B is 7.8' SW. This subgroup of AGC 3526 (Centaurus Cluster) is catalogued as Klemola 19.
17.5" (4/7/89): extremely faint, moderately large, round, very low surface brightness. Member of the Centaurus cluster (AGC 3526). Forms a pair with NGC 4601 5.3' NNW (not seen).
