Comet Jacques and Mu Cephei
Occasionally, comets cruise by Earth. Some more spectacular than others. This one is not too spectacular, as you can't see it with your naked eye and even with my telescope and this camera, you can't see the tail. However, it is my first picture of a comet, and it happens to be passing a very famous star in the picture, that is Herschel's Garnet Star (Mu Cephei). Google it to find out why it is so famous!
