After opening the observatory I relaxed on the observatory patio bench.

1849 MST: waxing gibbous Moon rose over the hill to the east.

1900 MST: LX600 ON, StarLock OFF, High Precision OFF.

Viewed the planet Venus, 102X. Then viewed Venus, 163X + Atmospheric Dispersion Corrector (ADC). Bright nearly full disk visible.

Mounted the iPhone 11 Pro Max on the 15mm eyepiece + ADC. Tried to do a slo-mo (240fps) video using the Camera app but it would not properly focus. Used NightCap Camera (ISO 32, 1/6393sec, 30 seconds, 30fps, 1X lens) to record the planet. This is a stack of 919 video frames, afocal 163X.

1917 MST: returned to the bench and took this iPhone Camera app (2X lens) photo of the Moon. The hill is reddened by the setting Sun.

1924 MST: sunset. Calm now.

1936 MST: viewed the planet Mercury, 163X + ADC. Very nice view of the crescent phase.

Mounted the iPhone on the 15mm eyepiece + ADC and did a video using NightCap Camera (ISO 32, 1/300sec, 30 seconds, 30fps, 1X). This is a stack of 921 video frames, afocal 163X, showing the crescent phase.

1952 MST: viewed the Moon, 102X and 81X.

Took this handheld iPhone afocal 81X photo of the Moon using NightCap Camera (ISO 32, 1/2000sec, 1X).

2000 MST: last look at the Moon, 102X.

2002 MST: LX600 OFF.
