William Herschel discovered NGC 6926 = H III-142 = h2079 on 21 Jul 1784 (sweep 242) and recorded "vF, E, nearly of equal light throughout and about 2' long. A patch of not very close small stars north following." His RA was poor (too large), but clearly applies to UGC 11588. On 12 Sep 1830, John Herschel logged "vF; pL; pmE; or two joined; nearly in the meridian [N-S]." On JH's first observation three years earlier, he discovered nearby NGC 6929.

400/500mm - 17.5" (7/16/88): fairly faint, fairly large, elongated NNW-SSE, broad concentration. Brighter of pair with NGC 6929 3.9' E. Also brightest in a small group (USGC U788) that includes NGC 6922.

17.5" (8/1/86): moderately bright, fairly large, elongated, slightly brighter core.
