M109 - Vacuum Cleaner Galaxy

Messier 109 (a.k.a. M109 or NGC 3992) is a barred spiral galaxy located in the constellation of Ursa Major and is approximately 83.5 Million light-years from Earth, making it the furthest object in Messier's catalog (source: Free Star Charts). The bright star Phecda (bottom cup star of the Big Dipper) makes fing M109 much easier.  For being so far away, it is still a relatively bright object. This was a last minute decision to image M109 and I couldn't pass on the opportunity.  Of course I would have liked to obtain more exposures but my window of opportunity is small due to overhanging trees.
