sword
This image is reversed right-to-left and rotated 90 degrees to the left. It shows the outline of Rupes Recta (the Straight Wall) as it appears when it is called "The Sword". In this light it looks a bit like a long-barreled flintlock pistol. The two large craters completely in shadow at the top, cut by the top edge of the photo, are Purbach (l) and Arzachel (r). The small round crater below the scarp is Birt and the similar but much larger one above it is Thebit. Rupes Recta is an escarpment about 114 km long and between 300m and 900m high. Image is a Registax-processed stack of 600 frames from a ToUCam Pro 840K, using a 2.5X Televue Powermate and Stellarvue 152mm apo.
