Cool

G'day Y'all
Would of thought 1/2000 sec, 1/500 sec, 1/250 sec, 1/125 sec, 1/60 sec combination of the lens aperture and shutter speeds as the shadow progresses will be needed.
A fast shutter speed will use a larger aperture (small F-stop number) to avoid an under-exposed image. A slow shutter speed requires a small aperture (large F-stop number) to avoid over-exposure.

NO star trails from that
