Lewis Swift discovered IC 5105 = Sw. XII-25 on 19 Aug 1897 and noted "vF, vS, R, * with dist. comp. n and s." His position is 5.4' too far south, but matches in RA. There are numerous stars around, so I don't know which stars he had in mind.

300/350mm - 13.1" (10/20/84): faint, small, round, brighter core. Just visible continuously with direct vision.
