☀13.4mag
Ø 60'' / 30''

CGCG 082-026, located 14' ESE, appeared fairly faint, very small, slightly elongated E-W, 15"x9", fairly high surface brightness.

Lewis Swift discovered IC 1255 = Sw. X-45 on 5 Jun 1891 and reported "vF; pS; R; Trapezium with 3 stars." His position is 2' too far south but the identification is certain based on his description of the 3 nearby stars.

600/800mm - 24" (7/21/17): at 375x; fairly faint, fairly small, elongated 4:3 SSW-NNE, 32"x24", contains a very small bright core that seems offset to the south side. A mag 15.1 star is just off the northeast edge. The galaxy forms the northeast vertex of a quadrilateral with a mag 12 star 2.4' W, a mag 11.5 star 2.3' SSE and a mag 10.5 star 3.5' SW.
