Truman Safford discovered NGC 6484 = Sf 41 = St VII-19 on 11 Jul 1866 with the 18.5-inch refractor at the Dearborn Observatory. Édouard Stephan independently discovered the galaxy on 27 Jun 1876. His micrometric position is accurate. As Safford's discovery list wasn't published until 1887 as the NGC was being prepared to go to press, Stephan is credited with the discovery in the GC Supplement and the NGC.

400/500mm - 17.5" (7/1/89): fairly faint, fairly small, slightly elongated WSW-ENE, small bright core, fairly faint stellar nucleus.

600/800mm - 24" (7/9/13): at 375x appeared bright, fairly large, slightly elongated E-W. Sharply concentrated with a relatively large, intense oval core ~30"x20", that gradually increases to the center. The core is embedded in a fairly large, low surface brightness halo that increases in size with averted to 1.5'x1.2'. MCG +04-42-010 and -011, a 30" pair of faint galaxies, are situated 5.8' NE. MCG +04-42-010 appeared faint, small, elongated 2:1 NNW-SSE, 24"x12", low even surface brightness. MCG +04-42-011, just 30" SE, was extremely to very faint, elongated 2:1 WSW-ENE, just 10"x5".

24" (6/8/13): at 282x appeared moderately bright to fairly bright, sharply concentrated with a fairly oval core of high surface brightness, ~24"x18", oriented SW-NE. The core is centered within a very low surface brightness halo, ~1.4'x1.0' E-W. Pou 3316, a mag 11.3/12.5 pair at 14", lies 4.2' SW. MCG +04-42-010 and -011, a close pair of faint edge-ons, lies 5.8' ENE; MCG +04-42-010 appeared very faint, small, elongated 5:2 NNW-SSE, 18"x8" and the companion -011 is very faint, very small, elongated 2:1 WSW-ENE, 12"x6". NGC 6484 is the brightest member of KTG 67 with UGC 11027 at 21' NE and UGC 11029 at 28' E.
