Lewis Swift discovered IC 275 = Sw. VIII-9 on 31 Oct 1888 and recorded "eeeF; pS; R; F * nr p; D * nr sp; bet. 3 st.; f of 2 [with IC 274]." His position matches V Zw 309, a triple system, with the brighter two components forming a 15" pair oriented N-S. Although the three components are listed in the PGC (from V Zw 309), neither HyperLeda nor SIMBAD labels any of the 3 as IC 275. Swift's "Double * near south-preceding" may be a ~30" pair ~2.5' SW

600/800mm - 24" (12/12/17): at 375x; faint, fairly small, roundish, ~24" diameter, low irregular surface brightness. IC 275 is a triple system with the two closer components IC 275 NED1 and NED2) separated by 15" N-S. I was confident that 2 or 3 extremely faint stellar or quasi-stellar nuclei were glimpsed and made a diagram of the orientation. Checking the SDSS at home, my diagram matches NED2 (north) and NED2 (south), along with a mag 15.8 star 18" NW of NED 2. I apparently missed IC 275 NED3, which is 30" E of NED2 and probably the faintest of the trio.
