Viewed Venus, 102X. The planet was a bright, nearly full phase, disk.

Viewed the waxing gibbous Moon, 102X.

1835 MST: began relaxing on the observatory patio bench after a hectic day of announcing that my autobiography, Finding my Way to the Stars, had been published.

Took this iPhone photograph of the Moon from the bench using the Camera app (2X lens).

Took this handheld iPhone afocal 81X photo of the Moon in the bright blue sky using the Camera app.

Then did some lunar observing, 271X. The craters Aristarchus and Copernicus were very nice at this high magnification.

Mounted the iPhone 11 Pro Max on the 2" 9mm 100° eyepiece using the Levenhuk adapter. Took this afocal 271X photo using NightCap Camera (ISO 32, 1/610sec, 1X lens) of the craters Aristarchus (left) and Copernicus (right).


Smoke from a new wildfire 12 miles south of Kitt Peak National Observatory (65 miles from Cassiopeia Observatory) was visible in the sky along the horizon from the south-southeast to west to north. This iPhone photo (0.5X lens, cropped) shows the smoke from the southwest to the northwest.
