The Pinwheel Galaxy (M33)

on Tuesday, October 30, 2012

The image is of the Triangulum Galaxy, M33, which is almost dead east and 70 degrees up at 11:30pm this month.  I lost 79 of the 100 exposures I shot due to condensation on my optics.  However, November should be colder and clearer (I hope), so I will try it again then.
