Modern observations
Walter Scott Houston
Houston calls this one of "two nice little galaxies that are easily found by starhopping from Alpha Trianguli ... it is a 2.5' by 1.1' elliptical, magnitude 12.1 ... in decent skies a 6-inch should do." Nearby lies NGC 672, and Houston notes: "They are less than one degree apart, so you should be able to squeeze them into a lower-power field."
