John Herschel discovered NGC 7169 = h3906 on 30 Sep 1834 and recorded "eF; S; R; difficult to distinguish from a * 15m; has a * 8m, distance 4' np, nearly in parallel, and another 11m, 60" nf." His position is 45 seconds of RA too far west, but the detailed description clinches this identification. The error in RA is noted in the ESO and SGC.
600/800mm - 30" (10/9/15 - OzSky): at 394x; fairly faint to moderately bright, fairly small, elongated 5:3 WSW-ENE, 0.55'x035', sharply concentrated with a very bright, small core and much fainter halo. A mag 13 star is 1.4' NE and a mag 15.5 star is just off the northeast end, 0.5' from center. Situated 3.2' ESE of mag 8.8 HD 209175.
