iPhone 13 Pro Max

Updated the International Space Station (ISS) TLE in the AutoStar for this evening's pass. Then prepared the D850 DSLR for imaging.

Viewed the Moon, 102X. Seeing was terrible.

Mounted the D850 DSLR at prime focus of the 12" telescope. Locked the 12" primary mirror. Took these photos of the Moon and Earthshine.

1/2sec, ISO 1000

Then began preparing for the ISS pass. Took this iPhone 13 Pro Max of the observatory with the 12" telescope pointed near the location of when the ISS would become visible low in the northwestern sky. The crescent Moon with Earthshine is visible near the top of the photo. The planet Jupiter is visible near the horizon at the right.


When the ISS pass began I did a 1080p, 30fps, video recording, 1/2500sec, ISO 2000, through the telescope. I lost the ISS in the telescope when it neared the polar region in the sky. And unfortunately, the telescope focus shifted, probably due to the rapidly decreasing air temperature after I had focused on the Moon. So there was no usable image of the ISS.

Viewed M42 (Great Nebula in Orion), 102X.

1903 MST: LX600 OFF.

Close: Friday, 4 February 2022, 1912 MST
