600/800mm - 24" (9/13/12): this superthin (axial ratio = 8.5) appeared as a very faint, very thin edge-on 7:1 SW-NE, ~1.0'x0.15'. The slightly brighter central region was sometimes only visible as the fainter tips were slightly more difficult to view. Located 2.5' S of mag 9.6 HD 155398. This is only the 16th galaxy I've logged in Ophiuchus and just the second UGC.
