Ormond Stone discovered NGC 2975 = LM 1-157 in 1886 with the 26" refractor at Leander McCormick Observatory. His rough position (nearest min of RA) is 1.0 tmin following and 1' north of PGC 27664, a typical error, so this identification is very likely.
400/500mm - 18" (4/14/12): extremely faint and small, round, 10" diameter. Required averted vision and could only hold for brief periods. There is a mag 15.5 star 35" NE that also occasionally popped and it was a bit confusing to disguish the two objects at 250x as they were about the same magnitude. A couple of times the galaxy and star both popped simultaneously.
