This is the southern end of Earth’s waxing gibbous phase Moon, as imaged late Tuesday night. The heavily-cratered area along the terminator includes Crater Tycho — with a central peak lit by the rising Sun — and the dark circular expanse of Clavius, with the top of its western crater wall extending into the deep shadows of the terminator. We used the old Celestron C11 for this session as we continue to evaluate its performance and condition. We continue to be concerned about whether the telescope’s focus issue is simple collimation or some more serious combination of problems.
