Discovered in 1786 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "a star about 8 or 9th mag with vF branch in direction of meridian, each branch 1' long."
An observer using the 72-inch f/8.8 speculum telescope at Birr Castle noted "Long, vF, vlbM. A bright star in preceding edge."
The RNGC (Sulentic and Tifft 1973) notes that this is a 10.5 mag galaxy. Their coded description reads EL,BM,HISBDISK.
Steve Coe, using a 13.1" f/5.6, notes: ""NGC 676 Very faint, pretty large, elongated 2 X 1 in PA 0 at 100X. This is a tough, low surface brightness object."

Description: Last stop on the Autumn Express tonight, was a bright galaxy which I've never seen before, stuck about midway between M74 and M77: the weird little spiral n676. A readily found brightish blur, near the center of the base edge of the isoceles triangle formed by the stars omicron, nu, and xi Psc. Too low and immersed in lightening haze to to show much detail, other than a considerable brightening at its very tight, circular core, and a hint of elongation N-S in its halo.
