Walther Crater – December 26, 2017

Walther Crater, on Earth’s Moon, measures about 85 miles across and was named after the 15th century German astronomer Bernhard Walther. I found a reference that stated Walther had a printing press that produced some of the earliest astronomical works.

Montes Apenninus – December 26, 2017

The cold, crisp evenings has made for some really good nights of lunar imaging. The temperature in the observatory hovered around 10F during both sessions. I took advantage of the last two nights to capture some wide field views using a combination of my Canon 6D and ASI290MC with an Antares Focal Reducer.  Here is a view of the Apenninus Mountains, best viewed just after the first quarter moon when they are draped in some shadows. The capture area was 1936 x 1096 and then slightly clipped.

Rupes Recta, a linear fault line, or rille, casts this interesting shadow during the first quarter phase of the moon giving the nickname the Straight Wall. This fault has a length of about 68 miles (110 kilometers). The small (11 miles wide) crater Birt lies just to the west.
