Forms a pair with CGCG 314-028 = Arak 293 9.7' E, at the edge of the 225x field. The Arakelian galaxy (catalogue of high surface brightness galaxies) appeared fairly faint, very small, round. Appears a compact fairly high surface brightness glow about 20" diameter.
William Herschel discovered NGC 3668 = H II-845 = h880 on 20 Mar 1790 (sweep 954) and noted "vF, pS." His position (CH's reduction) is 14 sec of RA west of UGC 6430. The mag 15 star superimposed on the northwest side is mentnioned in the UGC notes as a galaxy, but it appears stellar on the SDSS.
400/500mm - 17.5" (4/22/95): moderately bright, moderately large, elongated 3:2 NW-SE, 1.5'x1.0', mottled appearance. Well concentrated with an elongated core and a bright nucleus. A mag 15 star is superimposed at the northwest end 0.6' from center. Located 2.6' NE of a mag 10 star.
