Published comments

Burnham's Celestial Handbook

Burnham calls it a 12.6 mag barred spiral galaxy in Bootes, measuring 2.0' x 0.6', which is considerably bright, pretty large, elongated and pretty suddenly brighter in the middle.

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 12.5 mag galaxy. Their coded description reads EL,DIFWINGS.

Sandage, A. et al. (1975) Galaxies and the Universe

G. de Vaucouleurs ("Galaxies and the Universe", Chapter 14 - Nearby Groups of Galaxies) notes that the five brightest members of the NGC 5676 Group are NGC 5676, NGC 5660, NGC 5633, NGC 5689 & IC 1029.

NGC 5689 Donald J. Ware:"2'x0.75', oriented ENE-WSW, sharply concentrated to the center and a non-stellar nucleus."

Modern observations

Tom Lorenzin

Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "12.6M; 3' x 1' extent; soft, small slash surrounds brighter core; axis oriented E-W; SP GAL N5676 50' to NNW."

Steve Coe

Steve Coe, using a 13" f/5.6, notes: "Pretty bright, pretty large, much elongated 3 X 1 in PA 90 and much brighter in the middle at 100X. NGC 5693 is to the south and it is faint, small, round and not brighter in the middle."
