NGC1087+1090 Galaxies in Cetus

This pair of 2 to 4 arcminutes sized galaxies can be found in the constellation of Cetus,near of the famous bright galaxy M77.NGC1090 is far more away than NGC1087 (124 mio.lightyears to only 80 mio.lightyears) and therefore is actually much bigger.NGC1087 is propably the brightest member of the Abell381galaxy-cluster,southwest of NGC1087.

Both are about 13mag bright and have little surface brightness.Observing them visually with a telecope of even bigger dimensions may be a difficult thing.

NGC1087 is a SAB(rs)c barred-spiral,whereas NGC1090 is of type SB(rs)bc.The where two supernova events inside,one in 1962 and the other in 1971.The fist one was detected by William Herschel in 1785.
