I know---I don't need another image of M51. But I had a few hours and wanted to use the refractor. I always like the look of stars taken through it. Of course, with the H9C the scope is working far below full resolution. And I seemed to get a lot of red in the galaxy. Perhaps the sky was more transparent to Ha, or perhaps it was particularly opaque to blue. Either way, here is the result.
