To correct:

At 158x, the Copernicus region and the surrounding dark pyroclastic deposits of west and central Sinus Aestuum and Rime Bode had good contrast. http://members.csolutions.net/fisherka/astronote/plan/dhccat/DarkHaloCraters... At 560x, the dark halo crater Copernicus H (Rukl 31) could be distinguished as a DHC. Although seeing was poor, paradoxically, difficult lunar object Rima Gay-Lussac was visible with good detail to the north of Copernicus. (Rukl 31).
