400/500mm - 17.5" (12/23/97): At 220x the "A" component of HCG 25 is located just 1.1' following a mag 12 star and is a bit more difficult to view than HCG 25b which lies 4' NNE. Appears extremely faint, very small, elongated 3:2 or 2:1 NNW-SSE, ~25"x15". Both members of HCG 25 were easier to view at 280x.

900/1200mm - 48" (10/23/11): fairly bright, moderately large, elongated 2:1 NNW-SSE, 0.9'x0.45', broad concentration, small brighter core. A mag 12.2 star lies 1.1' WNW. HCG 25A, B, D and F share a similar redshift, but the redshifts of 25C, east and F are significantly higher. SDSS J032034.82-010545.1 lies 2.2' NW, on the NW side of the mag 12.2 star. It appeared extremely faint, round, 8" diameter.
