Image Details:

I read about dwarf planet, the first asteroid to be discovered, Ceres, passing by very bright Aldebaran in early November. I hoped I could aim at and focus on bright Aldebaran so I could catch it with my Canon XS and its zoom lens. I did, with the ISO sensitivity cranked up to the highest it goes on my camera, 1600. It was a cold morning (about 1C), so I didn't get noise from the heat of the camera.
