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.

Stofler Crater – October 27, 2017

Here is an image of Stofler Crater located on the southern section of the moon. The crater has been struck numerous time to the south and east. This was named after Johannes Stöffler (also Stöfler, Stoffler, Stoeffler) (10 December 1452 – 16 February 1531) who was a German mathematician, astronomer, astrologer, priest, maker of astronomical instruments and professor at the University of Tübingen (source: Wikipedia).
