Here images taken last night 2017-07-05 at 20h49'39"UT on 11,76 days of lunar phase but in this case faraway from lunar terminator to evidence dark alo craters inside Alphonsus. Image on left is a closeup of the floor with dark alo craters and theyr denomination, I hope it's correct. On the centre we can see a panoramic view on Ptolemaeus and Alphonsus craters taken on the same night faraway from terminator. Image on right is a panoramic view taken on 2015-12-19 at 17h18'27"UT on 8,28 days of lunar phase near lunar terminator.
