M45 from my backyard in heavy light pollution. The shots were taken on November 21st 2013. I forgot about them and I just foud them while cleaning the hard drive... 75x 75s @1600ISO, which was a test. I knew that my polar scope was not alligned with the RA axis of my mount (and still isn't perfectly) and wanted to see what would be the result with 75s exposure. I just never bothered with finnishing the picture so here is it.
