Lunar Crater Humboldt Details
Posted: 30 June 2017
Open: Thursday, 29 June 2017, 1856 MST
1903 MST: LX600 ON, StarLock OFF, High Precision OFF.
1904 MST: viewed Jupiter, 102X. Three moons visible against the bright blue sky 35 minutes before sunset.
Then viewed the Moon, 102X and 203X. Crater Humboldt was nice at 203X. Lots of details visible on the crater floor. Lunar libration has brought it into a good viewing position (see this Sky & Telescope article).

1939 MST: sunset.

Removed the focal reducer and added the 2X PowerMate for this image of the Moon, 1/320sec, ISO 1600, WB Auto, showing from the lunar terminator (left) to crater Humboldt (right):
