Another galaxy from previous week astrophoto sessions.
This time well known Sombrero Galaxy (Messier 104)
Rather difficult to photograph due to low altitude (in Poland) - registration od some detail is a real challenge.

It is spiral galaxy with aparent magnitude around 8,7 mag located in the constellation of Virgo. It has not well developed spiral arms and a dust belt (torus) which partially cover the galaxy which is set to us sideways.
