This is the star Algoreb, in the constellation Corvus. The only notable thing about this photo is that it is a 60 second exposure, and until tonight, I could not shoot pictures with such heady exposure times. However, it has a passing interest outside my own struggle to make my telescope work. Algoreb is a lovely double star (even in the smallest scopes, they are noticeably different colors), and the smaller partner, Algoreb B, is extremely bright in infrared. It's still cloaked in the gas cloud from which it formed, which it is heating up a lot; and is therefore very young. The two stars are actually very far apart, and form a "visual binary" pair; they actually have nothing to do with one another.
The name Algoreb has been applied to another star in the same constellation in the past. But the really interesting thing about this pair is that they represent one of the few things left in our world that you can't quickly learn about on the internet. Efforts to Google it give you a lot of information about Al Gore, but almost nothing about this star.
