Couldn't find anything "new" for the Explore the Moon (ETM) version but did view several previously viewed features for the ETM plus new ones for the Isabel Williamson Lunar Observing Program (IWLOP).
It was fun seeing features under a different light from previous observations. The "re-discovered" features viewed in a bit more detail were:
- Cassini and Vallis Alpes. Refer to IWLOP #68 - Montes Alpes & Vallis Alpes and Explore the Moon (Telescope) - April 19, 2021.
- Purbach with its line of crater that broke its north wall and continued onto its floor. Refer to IWLOP #73 - Regiomontanus & Purbach for more details.
- Walther to the south of Purbach also had an interesting line of craters across its floor. Refer to IWLOP #71 - Walther for details.
