I thought it would be interesting to see how close in I could get to the lunar surface, so I put a Televue 2.5x Powermate into the optical train. I was pretty blown away by the result! The large crater towards the bottom middle of the picture, with a small crater in its lower rim, is called Aliacensis. It is 52 kilometres wide and a maximum of 3.7 kilometres deep. Moving north-northwest from Aliacensis are the craters Werner, Blanchinus and La Caille. Crater Apianus is to its northeast and the large crater to its southwest, with several smaller craters and a central peak in its interior floor, is the crater Walter.
