Albert Marth discovered NGC 2713 = m 135, along with NGC 2716, on 3 Mar 1864 and logged "pB, iR, mbM." Heinrich d'Arrest independently discovered the pair on 15 Mar 1866. He noted a mag 10 star (SAO 117289) preceded by 18 sec of time and 46" south and measured an accurate position (2 nights).

300/350mm - 13.1" (1/18/85): moderately bright, elongated 3:2 WNW-ESE, fairly small, large brighter core. Forms a pair with NGC 2716 11' NNE. Located 4.5' ENE of mag 9 SAO 117289.

600/800mm - 24" (2/13/18): bright, large, elongated 5:2 WNW-ESE, strongly concentration with a large, bright, roundish core, ~45" diameter, and a faint stellar nucleus. The halo or arms are much fainter and gradually fade out but extend roughly 2.5'x1'. Mag 9.5 SAO 117289 lies 4.5' W. NGC 2716 is 11' NNE and IC 2426 is 17.5' E, forming the triplet UZC-CG 083.
