I tried this with a solar transit last year and discovered that my expensive phone can't keep time. Learned my lesson - for this lunar transit I shot video a few minutes before and after. The video is 4K and has the unedited 1 second transit and a zoomed in slow version where you can actually see the thing. Unfortunately this means the composite at the top is made from frames extracted using ffmpeg. Next time, two cameras, so I can attempt a burst as well as a video.

Caught the end of a SpaceX Starlink Train last night - image above is three stacked six second exposures.

We have to be six feet apart in space but so far there are no rules on time.

The transit of Mercury on November 11, 2019 shot from San Francisco, CA with a Sony RX10 IV with an ND5.0 filter (and a better filter adapter than this one).
