Messier Catalog Astrophotography with iPhone 11 Pro Max
Posted: 30 October 2019
Monday, 21 October 2019, was clear but I did not open the observatory. I was getting ready to attend the "First Annual David H. Levy Arizona Dark Sky Star Party" at Kartchner Caverns State Park in Arizona, 23-27 October. My wife and I had a great time at the Star Party. I have posted a report. Sunday, 27 October, was very windy and partly cloudy when we returned home. Monday, 28 October, was windy during the day and partly cloudy. The wind died down as sunset approached but there were still clouds in the southern sky. The sky cleared but some wind returned on Tuesday, 29 October. I had a special visitor that evening. I met Chad at the Star Party and he was staying in Arizona for awhile to attend the International Dark-Sky Association Annual General Meeting in November. So I invited him to Cassiopeia Observatory.

Crepuscular rays were visible in the western sky. This D850 DSLR photo shows the rays with the crescent Moon at the left.
We then viewed Venus, 102X; Mercury, 102X and 271X; Jupiter, 271X; and Saturn, 271X.
As the sky darkened Chad was definitely enjoying our Arizona night sky.
I began preparing to some more Messier Catalog iPhone 11 Pro Max astrophotography. The breezes had calmed down.
