900/1200mm - 48" (4/19/17): at 375x and 488x; bright, fairly large, edge-on 3:1 or 7:2 NW-SE, ~1.4'x0.4'. Very unusual asymmetric appearance with two thin spiral arms. Contains a bright, relatively large oval core NW-SE. A very thin bright arm stretches from the west side of the core towards the northeast, bending very slightly to the east. A symmetrically placed thin bright arm is attached on the east side of the core and stretches nearly straight southwest along the eastern flank, heading towards VV 286b, a merged companion ~45" SW of center at the edge of the halo. The surface brightness of the halo has a much lower, irregular surface brightness east of the northern arm and west of the southern arm. At 488x, VV 286b (interacting companion at the southwest end) appeared fairly faint to moderately bright, fairly small, oval 5:3 E-W, ~15"x9".
