Stars and Stripes

Westerly Star Trails

This 25minute exposure began about ninety minutes after sunset. I haven’t taken any star trails for nearly three years and was initially a little disappointed not to get the trails a bit closer to the horizon. However, looks can be deceiving and the lowest trails actually reach well below 10° from the horizon, where there was considerable murk visible before sunset.

As well as the star trails, there are three late-evening aircraft trails, as the number of flights begin to pick up, with all Australia’s interstate borders opening up again, post-covid.
