John Herschel discovered NGC 6890 = h3824 on 1 Jul 1834 and recorded "F; R; vglbM; 15"." On a second sweep he logged "pB; S; R: gbM; 25"." His position is accurate. In a group with NGC 6878 50' WNW.
600/800mm - 24" (9/15/12): at 175x appeared moderately bright and large, elongated 4:3 NNW-SSE, 1.2'x0.9', brighter core. The view was compromised by low altitude (less than 10° elevation), fairly poor seeing and sky glow near the horizon. A number of ESO galaxies are within 1° NW, though they were too faint to be seen in these conditions except for NGC 6878 50' NW. Possibly a member of the Telescopium Group.
