Heinrich d'Arrest discovered NGC 7149, along with NGC 7148 (just a double star) on 15 Sep 1865 with the 11-inch refractor at Copenhagen. His position (3 measurements) is accurate.

400/500mm - 17.5" (8/1/86): faint, small, round, weak concentration. On a line close south are two stars; a mag 14 star 0.8' SSW and a mag 12 star 1.4' SSW of center. Brightest of three with NGC 7146 and NGC 7147 15' SSW.

600/800mm - 24" (9/22/17): at 375x; fairly faint, moderately bright, sharply concentrated with a bright oval core that increases to a very small brighter nucleus. The core is slightly elongated along the major axis. The outer halo is ~0.8'x0.6' and has a very low surface brightness. A mag 12.3 star is 1.4' SSW.

IC 1407 (misidentified as NGC 7148 in RNGC and PGC) lies 14' NNE. It appeared fairly faint, small, round, 24" diameter, very faint stellar nucleus. This is a double system (II Zw 152), but the nearly stellar companion (PGC 67535) at the WNW edge was not resolved.
