William Herschel discovered NGC 5737 = H III-896 = h1871 on 20 Apr 1792 (sweep 1021) and recorded "eF, S, vlbM." JH made the single observation "vF; pS; R; glbM" and measured an accurate position.

400/500mm - 17.5" (7/16/01): faint, moderately large, slightly elongated, 1.1'x0.8', weak concentration, irregular surface brightness. Forms the vertex of an isosceles triangle with two mag 10 stars 4' N and 4' E. Viewed low in the west with decreased transparency.
