NGC 7556
24" (9/29/16): at 375x and 500x; fairly bright, moderately large, elongated 4:3 or 3:2 WNW-ESE, ~0.8'x0.5', well concentrated with a bright core, high surface brightness. Surrounded closely by several smaller and fainter companions including NGC 7554 48" W, NGC 7556A just 19" SW, LEDA 195267 1.4' SE and LEDA 195265 3.3' SSE. A mag 10.6 star is 2.7' E.
At 500x; NGC 7556A appeared extremely faint and small, round, ~8" diameter. Situated at the southwest edge of the halo of NGC 7556. At 375x LEDA 195267 appeared fairly faint, small, round, 15" diameter. LEDA 195265 was a difficult object, extremely faint and small, round, 6" diameter.
17.5" (8/1/87): moderately bright, moderately large, oval ~E-W, bright core. Forms a close pair with NGC 7554 47" WNW of center. Brightest in the large NGC 7532-7556 group.
