Perfectly round shape on the moon.

I just took this photo. Although the picture is pretty mundane, I observed something I have never seen before: The perfectly round circle on the bottom of the moon (bottom right hand corner).

At first I thought it was a crater, but it looks too perfect. What could it be?

What are the shiny dots all over the moon?

Nice photo. All the things you ask about are craters. The large one is Tycho.

You can also zoom and pan in

A view with Tycho centered is:
