Christian Peters discovered NGC 3492 around 1880 with the 13.5" refractor at the Litchfield observatory in New York. It was not published in either of his two lists of 1881 and 1882, so the discovery was probably communicated directly to Dreyer. His NGC position matches UGC 6094.

400/500mm - 17.5" (4/25/98): faint, fairly small, slightly elongated ~E-W, 1.0'x0.8'. Weak, even concentration to a slightly brighter core and nucleus. This galaxy is the brightest in AGC 1142 with IC 664 4.1' NW, IC 663 6.4' SW and IC 666 4.6' SE. Observation made in hazy skies.
