An edge-on galaxy at 1.5 degrees north of α Trianguli is UGC1281. Although the 13th magnitude galaxy has a comparatively longer length of 4.5 arc minutes, a major catalogue of NGC has leaked registration. UGC1281 has been classified as a dwarf galaxy; number of contained stars is small and the central bulge has little developed. The edge-on dwarf galaxy is a good subject for study of the inner gaseous distribution. The Hubble Space Telescope has captured a detailed image of the galaxy and various researches has been performed.
