Heinrich d'Arrest discovered NGC 2064 near M78 on 11 Jan 1864. He noted a mag 9-10 star was 4' north-preceding and measured an accurate position (2 nights). The visual extent is much smaller than the catalogued dimensions.

300/350mm - 13.1" (2/25/84): very faint reflection nebula, small. Located 7' WSW of M78 and 4' SE of a mag 10.5 star. This difficult object is near the visual threshold.

400/500mm - 17.5" (12/20/95): very faint reflection nebula in the M78 complex, but clearly visible. Appears elongated 2:1 SW-NE, at most 2'x1'. There are no involved stars. Located 7' SW of M78 and 4' SE of a mag 10.5 star. The large listed dimensions refer to a very elongated strip extending NNE on the west side of M78.
