So I decided that I would test my CCD video hardware on the moon. Using a 5min video (unfortunately I had poor alignment) I managed to stack this image.
To give you an idea of what scale this is, the crater at the bottom is the Tycho crater. Its diameter is roughly 86.2km. So that would make this shot approximately 430km wide x 300km high. I think if I was looking at the earth from the moon, I could fit the state of Pennsylvania in the frame!
