Messier 91 (M 91)

Introduction | Map | My Own Photos | Own Observations | References

On this page I collect my observations of the spiral galaxy M 91 (NGC 4548) in the constellation Coma Berenices.



The spiral galaxy M 91 in the constellation Coma Berenices is the faintest Messier galaxy in the Virgo cluster and the faintest Messier object ever (according to Stoyan). Considering this, my result with the eVscope is quite acceptable. In the eVscope, the bar can be recognized, the spiral not so much...
