This video starts off the same as the one above but watch the picture change by looking at the shadows. The area above the ridge sure does look more detailed when the shadows are this way. many astronomers are unable to capture images when the shadows are like this as during the days of the year this is possible it is usually overcast. These are rare images. Enjoy. I tried to do an HD version but the upload kept failing. Even so it's not too bad quality when viewed using the high quality option.
