Messier 91 |
 | 
| |
 | M91 is a spiral galaxy of type SBb in the constellation Coma Berenices. The bar is quite conspicuous. M91 was considered the `lost' Messier object. M91 is a member of the Virgo Cluster of galaxies, which is the dominant cluster in our Local Supercluster and about 60 million light-years away. In a 8-inch scope, this is a faint galaxy. There are some faint field stars nearby, but even they are brighter than the galaxy. At low power, it is just a dim elongated smudge. The arms themselves could not be seen. Increasing the magnification reveals a brightening of the non-stellar core. |
