NGC 4117
24" (5/30/16): fairly faint to moderately bright, fairly small, very elongated 3:1 SSW-NNE, 0.9'x0.3', well concentrated with a small bright elongated core with faint extensions. Forms a pair with NGC 4118 1.8' SE. NGC 4111, the brightest member in a group, lies 8.6' SW and orange mag 8.1 HD 105288 (wide pair) is 5' WSW.
17.5": fairly faint, fairly small, oval SSW-NNE, weak concentration. Forms a close pair with faint NGC 4118 1.6' SE and NGC 4111 lies 8.5' WSW. The double star h2596 = 8.2/10.7 at 34" is 5' WSW.
13" (4/12/86): fairly faint, small, elongated SSW-NNE, broadly concentrated. Located on the opposite side of a mag 8 star from NGC 4111.
