This interesting chain of four MCG galaxies lies only 18 arcminutes NNE of NGC 247, a giant member of the nearby Sculptor Group. (NGC 247 itself is 9th-magnitude but of very low surface brightness, which can make it tough to spot in a smaller scope.) The northernmost and southernmost members of the chain are relatively easy to pick up in a 17.5" scope.
17.5": brightest and furthest north of trio in "Burbidge's Chain" (VV 518). At 220x, appears faint, small, elongated 5:2 SSW-NNE, 0.8'x0.3', even surface brightness. Located 1.2' S of a mag 12 star. Collinear with E540-024 3.4' S and E540-025 5.5' S! Located 18' NNE of the huge galaxy N247.

17.5": this is a marginal galaxy in Burbidge's Chain (VV 518), sandwiched between E540-23 just 3.4' N and E540-25 2.0' S. Required averted vision and only popped into view momentarily as a threshold 15" knot. A mag 14 star lies 1.5' W.

17.5": furthest south of three members view in Burbidge's Chain (VV 518). Appears extremely faint, small, roundish, ~25" diameter. Requires averted though can almost hold continuously with concentration. E540-024 lies 2.0' N.
