 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.
