The International Space Station (ISS) would pass very close to the planet Mars this session. Just how close I was not able to determine exactly. Although there were clouds in the sky that might interfere with imaging the close pass I decided to set up the D850 DSLR with a 150-600mm lens on the observatory patio.

This photo taken with an iPhone 11 Pro Max shows the camera, the planets Saturn and Jupiter at the top, the crescent Moon, and some clouds.


While waiting for the ISS pass to begin I took these images of the Moon using the D850 DSLR.

Crescent Moon (f/6.3, 1/1000sec, ISO 1600, FL 600mm, cropped)

Earthshine, stars, thin clouds (f/6.3, 1 second, ISO 1600, FL 600mm, not cropped)

As the ISS passed Mars I did a D850 DSLR video recording with Mars at the left of the field-of-view at FL 600mm. Unfortunately, the station was just outside of the field. Oops.

I then began waiting to see if the slowly moving clouds would move on.

1925 MST: I gave up.
