Clementine
In this Clementine frame, the southern member of the Omar Khayyam system looks "separated" from its somewhat larger companion to the north. Now, who of the two is the real Omar Khayyam? Or is it both craters together?
Libration chart 1 (page 182) in Antonin Rukl's Atlas of the Moon shows the Omar Khayyam system as one unit (no trace of two craters).

- Omar Khayyam was captured in Lunar Orbiter IV's frame LO-IV-190-med, in which its shadowed interior is noticeable at the western part of Poczobutt's floor (not far from the local morning terminator).

- During each one of the lunar Apollo missions (Apollo 8, 10, 11, 12, 13, 14, 15, 16, and 17) crater Omar Khayyam was in total darkness. There was no Earthshine because Omar Khayyam's location is on the moon's northwestern farside. The only light came from the billions of distant stars scattered all over our galaxy, and perhaps there was also a very little bit of reflected sunlight from the sunlit dust particles in the plane of our solar system, and... some planets. - DannyCaes Aug 31, 2013
- On the other hand, a quick look at Libration Chart number 1 (in Antonin Rukl's Atlas of the Moon) reveals the location of Omar Khayyam within this libration zone, which means it could have received local low-to-the-horizon Earthshine during one or more Apollo missions. - DannyCaes Aug 31, 2013
