John Herschel discovered NGC 6758 = h3781 on 9 Jun 1836 and noted "pB; R; 20"." His position is fairly accurate. Joseph Turner observed and sketched the galaxy on 2 Aug 1877 with the Great Melbourne Telescope. He noted a diameter of about 25", gradually brighter in the middle, 3 faint stars forming an obtuse triangle follows.

200/250mm - 11" (8/8/04 - Haleakala Crater): at 127x appeared fairly faint, fairly small, round, 0.8' diameter, broad concentration, very small brighter core. Three IC galaxies are within 20' (IC 4829, 4832, 4840), but I didn't search for these. Viewed at an elevation of 13°.

600/800mm - 30" (10/14/15 - OzSky): at 303x; bright, large, oval 4:3 WNW-ESE, 1.5'x1.2', sharply concentrated with an intense core that increased to a very small, extremely bright nucleus. A 9" pair of mag 15-16 stars lies 1' NNE of center. Brightest in a group with ESO 184-036 3.9' NNW, ESO 184-033 8.3' WNW, ESO 184-026 16' WNW.

ESO 184-033 is moderately bright, fairly small, round, 0.6' diameter. ESO 184-026 appeared fairly bright, fairly large, elongated 5:3, sharply concentrated with a small very bright core.
