I started observing the Moon then realized that Jupiter would be setting before I finished with the Moon so switched targets then got Neptune before moving back to the Moon

The terminator passed through Aristarchus and Schicard.

Montes Carpatus were not visible. Individual peaks of Montes Alpeninus were visible but not the range. A lighter color in the area is the only indication of Montes Ch\aucusus and Montes Alpes. The inside of NE Sinus Iridum is very bright where the Jura Mountains are lit up.

Mare Crisium looks like a lake emptying through a river at Proclus with Palus Somni fanning out into the ocean of Mare Tranquilitatis as a delta.

In low power there were some rays emanating from Copernicus and fewer from Tycho. The ray up through the middle of Mare Serenitatis is visible.
