Forms a pair with ESO 140-043 4.4' SSW. This galaxy appeared faint, moderately large. Its sharply concentrated appearance was unusual with a very small, very bright elongated core surrounded by a very faint, ill-defined halo, ~1.5'x1.0' N-S. In addition, IC 4751 and 4753, a 1.6' pair, lies 16' NW and IC 4754 is 20' NNW.

John Herschel discovered NGC 6673 = h3755 on 7 Aug 1834 NGC and recorded "pF; R; psbM; r; 25"." His position (measured on two nights) is accurate.

600/800mm - 30" (11/3/10 - Coonabarabran, 264x): bright, fairly large, elongated 2:1 SSW-NNE, sharply concentrated with a very bright core. A star is just off the east edge and at the south tip. A mag 9 star (HD 172584) is in the field 7.5' SSE. Located 50' W of mag 4.1 Lambda Pavonis and 21' WSW of mag 7 HD 173167.
