M94 - The Starburst Galaxy

Messier 94 (a.k.a. as NGC 4736 or Starburst Galaxy) is a spiral galaxy in the constellation Canes Venatici and lies approximately 14.5 million light-years from Earth.  Compared to the Milky Way, this galaxy is about half the size with a diameter of 50,000 light-years across.  It has a bright nucleus compared to other galaxies and really does have a brownish tint.  Looking at Hubble images you can see a lot of dust within the spiral arms. There is also an outer bluish ring, faint in my image with my little ED80 - larger scopes will do a better job with this, where young massive stars are forming. (source: wikipedia, APOD).
