Edward Swift, son of Lewis Swift, discovered IC 1129 = Sw. VII-57 on 13 Jul 1887. Swift logged "vF; pS; iR; D * nr. nf." The double star is mentioned in my observation.

600/800mm - 24" (7/20/17): at 375x; moderately bright, fairly small, roundish, ~40" diameter. Contains a bright, round core. The halo increases in size with averted vision and changes in shape/orientation like low surface brightness spiral arms. A 25" pair of mag 11.7/12.6 stars lie 5' NE.
