RI: Located Schickard and identified at least 3 craters in the SW floor of the oblong crater.
R2: Found the Lacus Excellentiae between Schickard and Mare Humorum. The Lacus looked darker and was certainly bordered by numerous small craters.
R3: Clausius is on the W side of the Lacus Excellentiae.
R4: Lehman
appeared to "drain" into Shickard. Maybe just dark(?)

C1: The crater Lee's sides are greatly eroded, especially those facing Mare Humorum. Vitello has what appears to be a large peak just off-centre on the E side, and has either a shadow or opening towards Mare Humorum.
