The first quarter moon was almost directly overhead, making it an excellent day for lunar imaging especially since the seeing was better than average.
This field of view is almost directly at the center of the moon and shows a number of very large craters. Rimae Triesnecker, a complex area of rilles is shown at the very top, slightly to the left and just east of crater Triesnecker.

It was named after the Greek astronomer, geographer and mathematician Hipparchus.[1] It is located to the southeast of Sinus Medii, near the center of the visible Moon. To the south is the prominent crater Albategnius, and to the southwest lies Ptolemaeus, a feature of comparable dimensions to Hipparchus. Horrocks lies entirely within the northeast rim of the crater. Halley is attached to the south rim, and Hind lies to the southeast. To the north-northeast is the bowl-shaped Pickering, and the flooded Saunder is located off the northeast rim. High-resolution images of Hipparchus were obtained by Lunar Orbiter 5 in 1969.

Hipparchus seen by Apollo 16This feature is an ancient crater that has been subject to considerable modification due to subsequent impacts. The western rim of Hipparchus has been all but worn away from impact erosion, and only low hills and rises in the surface remain to outline the feature. The wall to the east is somewhat more intact, but it too is heavily worn. A pair of deep clefts lie in the western wall. These parallel a sets of scars running through the south-central highlands. The crater floor has been partially resurfaced by basalticlava flow. The southwest part of the floor, however, is slightly raised and much more rugged than the remainder. A few small rises and the raised partial rim of a flooded crater are all that remain of a central massif. Gaps in the northwest rim of Hipparchus form valleys that connect with the mare to the northwest. A rille named Rima Réaumur runs from this site to the outer wall of Réaumur.

 Hooke's Observations

Robert Hooke's observations of the lunar crater Hipparchus, 1665In October 1664, Robert Hooke used a 36-foot telescope to make a detailed drawing of the single crater Hipparchus and surrounding terrain, which he published as a plate in his Micrographia (1665).[2][3] His drawing contained an abundance of detail, and can be considered the first high-definition illustration of an individual lunar feature. Hooke argued that its features were not fixed, but were a product of ongoing physical forces. He suggested two possible models to explain lunar crater formation: projectile bombardment from space and subterranean lunar vulcanism. Less accurately, he speculated that the crater might contain "verdant pastures" and "Vegetables analogous to our Grass, Shrubs, and Trees”.[2]
