Lewis Swift discovered IC 4926 = Sw. XI-186, along with IC 4931, on 6 Jul 1897 and recorded "eeeF; pS; lE, precedes the below 37 sec; e diff; p of 2 [with IC 4931]." Swift's positions were 3' too far south and about 15 seconds of RA too small in his fourth discovery list from Lowe but pretty accurate in his accumulated 11th list (perhaps from Herbert Howe).

400/500mm - 17.5" (8/3/94): moderately bright, round, 1.2' diameter, even concentration to a bright core. A stellar nucleus is visible with direct vision. Forms a similar pair with IC 4931 7.5' E. I also ran across PGC 93980 11' SE and 3.7' WSW of mag 7.4 SAO 211735. It appeared very faint, small, round, very weak concentration. ESO 339-017, 3.7' N, was not noticed. Member of the rich galaxy cluster AGC 3656.

600/800mm - 25" (10/15/17 - OzSky): at 397x; fairly bright, round, ~45" diameter, strongly concentrated with a bright, well defined round core that increases to the center. Slightly fainter and smaller of a pair with IC 4931 7.4' E in the core of AGC 3656.

ESO 339-017, located 3.8' N, appeared fairly faint, elongated 4:3 ~N-S, small bright core, ~45"x35".

MCG -06-44-003, located 5.1' NNW, appeared fairly faint, fairly small, round, 25" diameter, very small bright nucleus. The view is affected by two superimposed stars; a 12th mag star on the north end and a fainter star on the east edge!
