The central peaks of 198 km wide Belkovich are right on the 90°E meridian, and here we can see a little beyond to the far rim of the giant crater. Belkovich A is a broad, smooth-floored crater with the simple crater B inside it. Hayn is a fresh crater with central peaks. Here you can see a characteristic of peaks - they are much lower (almost always) than the walls of their craters. The crater Hayn A is unusual for having a curved fracture on its smooth floor - is this the first telescopic image to show it? The large crater at the bottom of the image is Endymion with its little triplet and smaller craters that seem lined on rays and thus are probably secondaries. Have you figured out that the broad patch of mare, surrounded by two mountain arcs is the Humboldtianum Basin?

(1) In answer to the first question: it lacks the clarity of Jérôme's photo, but the shadow cast by the scarp in Hayn A at a lower sun angle is visible in Plate A1 of the Consolidated Lunar Atlas. - Jim Mosher
