Opened: Monday, 10 March 2014, 1825 MST
Temperature: 78°F
Session: 661
Conditions: Mostly clear, some clouds in west

1830 MST: Sunset. Viewed Jupiter, 83X. Four moons visible; Great Red Spot rotating out of view. Then slewed to the waxing gibbous moon. Took this handheld iPhone 5s photo, afocal 83X, through the 8" LX200-ACF:


Did a lunar tour using 222X. Seeing was not very good. During brief moments of good seeing, the craters Copernicus and Clavius looked very nice, with lots of details visible. By 1900 MST, with the moon very high in the sky, seeing at the moon had not improved. The clouds that had been low in the western sky were now getting higher in the sky. Added the 2X PowerMate for 444X and viewed the lunar terminator. During the now very brief moments of good seeing, had nice views of Copernicus and Clavius.

Did some iPhone 5s slo-mo (120fps) videos afocal 444X. These are single frames from the videos, cropped:



1910 MST: Clouds now at the zenith. Moon was in the clouds. Clouds were now also in the northern sky. Decided to close up for the night.

Closed: Monday, 10 March 2014, 1937 MST
