I captured this 100-second-long image of the spiral galaxy M101 (NGC 5457) in Ursa Major and a tumbling satellite or upper rocket stage on the morning of February 3, 2012, using the Bradford Robotic Telescope's 14" f/11 Celestron C14 SCT and FLI MicroLine camera located on Tenerife in the Canary Islands. A Celestron focal reducer yielding an effective focal length of 1877mm at f/5.3 was employed.  For further information on M101 (the Pinwheel Galaxy), browse http://messier.seds.org/m/m101.html
