Everything was perfect Saturday night when I captured this image of Alphonsus and Ptolemaeus. I counted probably three dozen craterlets
inside Ptolemaeus including Catena Davy and another crater chain to the right of Ptolemaeus. I used my 9.25 SCT with a 2X Barlow and a
ZWO ASI120MM monochrome camera. This is my finest image of the moon so far.
