The image here is from around the lunar sea Mare Nectaris region showing the 30km terraced wall crater Madler, the larger 100km crater Theophilus at the top with its imposing central mountain, crater Cyrillius and carter Catherina.  Mare Nectaris, is a round basin with a diameter of approx 360 km and an area of a little over 100,000 square km making it geographically smaller than the area of England and at least 3.8 billion years old.  A stacked image from a Philips SPC900 webcam and a Skywatcher 200p telescope.
