Bailly Crater on Earth's Moon

I imaged Bailly Crater on February 25, 2021, luckily the illumination provided enough shadow for a decent image. The unstable atmosphere and winds only allowed me to grab about 2000 frames during each run, so the final image is not as crisp as I would like it. From Wikipedia - One of the largest wall-surrounded plains on the moon, almost a "sea" in miniature, extending 150 miles from N. to S., and fully as much from E. to W. Named in honor of Jean Sylvain Bailly; French astronomer (1736-1793).

Tycho Crater – diameter is 86 km and it is about 4.8 km in depth, located in the southern region of the moon. The crater was named after Danish astronomer Tycho Brahe (1546–1601). From Wikipedia, “The crater is sharply defined, unlike older craters that have been degraded by subsequent impacts. The interior has a high albedo that is prominent when the Sun is overhead, and the crater is surrounded by a distinctive ray system forming long spokes that reach as long as 1,500 kilometers. Sections of these rays can be observed even when Tycho is illuminated only by earthlight.

Meteorite Impact During Eclipse

There was some discussion after the recent total lunar eclipse about a possible meteorite impact occurring. After scrubbing my data, it looks like I captured it around the same time as it was reported.

Montes Apenninus - September 18, 2018

The Apenninus Mountains is one of my favorite locations on the moon, probably best view just after the first quarter moon when they are draped in some shadows.
