Thursday, 18 November 2021, dawned clear, but clouds and wind began arriving mid-day with a forecast of an overcast sky for the near Total Lunar Eclipse. Fortunately, the Moon was visible throughout the eclipse.

Open: Thursday, 18 November 2021, 2248 MST Temperature: 59°F

Session: 1697 Conditions: Mostly cloudy (thin)

Equipment:
12" f/8 LX600 w/StarLock
2" 24mm UWA eyepiece
2" 50mm eyepiece

Camera:
iPhone 13 Pro Max
D850 DSLR

SYNCed the observatory clock to WWV time signals.

2254 MST: LX600 ON, StarLock OFF, High Precision OFF.

2300 MST: Dome OFF.

Viewed the Full Moon, 102X and 49X.

2302 MST: took this handheld iPhone 13 Pro Max photo of the Moon on the Dome using the Camera app (Night Mode, 3 seconds, 1X lens) at the start of the Penumbral Eclipse phase. Some of the clouds are visible.

Attached the LiDAR cover on the iPhone and mounted the phone on the 2" 50mm eyepiece using the Levenhuk adapter. I took afocal 49X photos of the Moon as the eclipse progressed using NightCap Camera. Between images I relaxed on the observatory patio bench. The Full Moon was bright enough to read by. The clouds thinned out as mid-eclipse approached and thickened back up after mid-eclipse. At times I used 12x50 binoculars to view the eclipsed Moon.

2309 MST: iPhone afocal 49X photo of the Full Moon shortly after the Penumbral Eclipse phase began.

0203 MST: iPhone afocal 49X photo of the Moon at Mid-Eclipse.

0206 MST: D850 DSLR photo (f/5, 4 seconds, ISO 800, FL 185mm) showing the eclipsed Moon and the Pleiades (M45).

This is a montage of the iPhone 13 Pro Max photos of the Moon as the eclipse progressed from the start (upper left) to the end of the Partial Phase (lower right).
