Description

A beautiful face on galaxy in Ursa Major, M101 is better known as the Pinwheel Galaxy (NGC 5457).  Approximately 50% larger than our own Milky Way Galaxy, M101 is asymmetric because of the influence of companion galaxies better seen in the wide field first version. At an apparent size of slightly more than 28', it is a nice size target for the Esprit 100.  Last year, the first submission had only 1 hr 44 min of data, but this image is a compilation of nearly 10 hours of data collected over 3 nights.
