M100 - The Blowdryer Galaxy

Last week proved to be pretty good for a couple of nights anyway as I was able to capture several of the Virgo galaxies.  This one, Messier 100 (a.k.a. M100 or NGC 4321) is a spiral galaxy located within the southern part of constellation Coma Berenices. It is one of the brightest and largest galaxies in the Virgo Cluster, located approximately 55 million light-years distant from Earth and has a diameter of 107,000 light years (source: wikipedia).

This also happens to be my 80th Messier object imaged with the Orion ED80 F/7.5 Refractor.  I am definitely seeing the light at the end of the tunnel although it my take another year.
