NGC 7028 is the designation of a celestial object in the constellation of Delphinus. The object was supposedly discovered by the German astronomer Albert Marth on 17 September 1863.[3] However, its identification is uncertain, and the object is considered lost.[4] No galaxies or nebulous objects are at the coordinates that he gave.[4]

One candidate is a spiral galaxy designated UGC 11676, or CGCG 448-039.[1] [4] It has an apparent magnitude of 14.8,[1] and is "very faint, small, very little extended",[4] just as Marth described.[4] While the declination of this object matches that of Marth's description, the right ascension is 2.5 arcminutes off.[4]
