Arp 92 in Pisces consists of
NGC 7306 (PGC 71035, UGC 12493, VV 1975 and others), the spiral left of center and PGC 71041 (
NGC 7396B and others), the elliptical companion. Part of Arp’s, ‘Spiral Galaxies – Companions on Arms – E Galaxy Companions’, these two might just close front our vantage point.
NGC 7306 appears to be about 413 million light-years away but the companion appears to be over 700 million. These two look like M51.
NGC 7589 (PGC 70995, MCG+00-59-019 and others) is the spiral to the right of center. It is located approximately 403 million light-years away.
