1814 MST: LX600 ON, StarLock OFF, High Precision OFF.

Viewed the gibbous Moon, 102X, 81X, and 163X.

Using the D850 DSLR with 150-600mm lens I took this (cropped) photo of the Moon (f/8, 1/640sec, ISO 640, FL 600mm).

I then mounted the iPhone 11 Pro Max on the 2" 30mm eyepiece using the Levenhuk adapter for this afocal 81X photo of the Moon taken with NightCap Camera (ISO 32, 1/3000sec, 1X lens).

Added the 2X Powermate for these afocal 163X images of the Moon (1X lens).

I then used the iPhone 2X lens for these afocal images of the Moon.

I did some lunar observing using the 2" 14mm 100° eyepiece (174X). Lovely sights.

I switched to the 2" 5.5mm 100° eyepiece (443X) and did some tours of the lunar surface. Some nice sights. I "discovered" the Bear Face Crater. This is a stack of 2562 video frames taken with the iOS Camera app (slo-mo, 240fps, 1X lens, afocal 443X) showing the "bear face" at the center.

Mouseover or tap on image for pointers to the face

The crater is actually Crater Doppelmayer, named for Johann Gabriel Doppelmayer, a German mathematician and astronomer (1671-1750). I couldn't find any reference to anyone mentioning the "bear face" so I guess I get "credit" for the "discovery"!

Next, I viewed the Trapezium star cluster in Orion, 443X. Then viewed M42 (Orion Nebula), 102X.

1912 MST: LX600 OFF.
