NGC4725



As the weather continues to be “Stormy” along the southeast, my hopes of finishing this picture are dwindling.  Looks like I’ll add it to the list of shots to complete on the spring next year.   NGC 4725 is an intermediate barred spiral galaxy about 40 million light-years away from our home planet in the constellation Coma Berenices.
