NGC 494
24" (10/4/13): moderately bright, moderately large, elongated 5:2 WNW-ESE, 50"x20", large bright elongated core. A mag 15.5 star is at the south edge [16" from center]. A wide pair of mag 13.5 stars lie 1.4' SW and a similar star is 1.4' SE. Located near the center of the NGC 507 Group with IC 1685 2.6' NE, NGC 504 7' ENE, NGC 507 11' NE and IC 1682 10' NW. IC 1685 appeared very faint, extremely small, round, 10" diameter.
13.1" (8/8/86): fairly faint, very elongated 3:1 ~E-W, bright core. A wide mag 13 double star at 30" separation is just 1' SW. Forms the vertex of a right triangle with mag 7.8 SAO 54647 8' NNE and mag 8.7 SAO 54632 11' WNW. First in a group with NGC 504 7' ENE, NGC 507 11' NE, NGC 508 12' NE and IC 1685 2.5' NE (seen in 17.5" only).
