 This series was taken a day before the
            full moon in December and features the huge walled plain Bailly
            on the south limb. Bailly is 183 miles in diameter and severely
            foreshortened on the limb. It is Nectarian in age, The image
            on the left was with the 1.8x barlow and is seeing limited. On
            the right is a wider prime focus image and shows Tycho in the
            lower left corner. On the bottom I've mostly rectified the image
            to show what Bailly would look like from nearly above.
