400/500mm - 18" (11/6/04): extremely faint, thin edge-on NW-SE, ~1.2'x0.15'. In fairly poor seeing, only glimpsed intermittently as the seeing sharpened at 160x. Situated close west of a mag 9.7 star. Position and orientation verified on photos. UGC 711 is an extreme case of a "Superthin galaxy".

900/1200mm - 48" (10/29/19): at 375x and 610x; fairly faint, large, very elongated superthin, roughly 12:1 NW-SE, 2.7' x 0.2'. The central region (core) was slightly brighter, but there was no bulge or nucleus. A mag 9.7 star is 1.9' E of center, but close off the SE flank.

A distant quasar, LBQS 0106+0119 = LEDA 2818340 at z = 2.10, lies 3.5' S. At 610x, it was barely glimpsed (V = 18.4) in poor seeing and wind. A 17th mag star, ~40" W, helped to pinpoint the position.
