Star Trails

I spent a few days at Ulladulla last week, a coastal town 180 kilometres south of Sydney. With no telescope to amuse myself with, I decided to try my luck with some star trail photography from the balcony of our accommodation.

This image shows the apparent motion of the stars in a clockwise direction near the South Celestial Pole, due to the rotation of the Earth.

Exposure: approx. 51 minutes (99 x 30 sec), ISO 100, f/2.8.
Date: 2018-02-27.
Location: Ulladulla, NSW.
Environment: coastal town.
Cloud: some.
Moon: high, gibbous waxing (11 days).
Processing: Canon DPP > StarStax > GIMP.
Cropping: no.

Imaging camera: Canon EOS 60D.
Mount: camera tripod.
Intervalometer: Yongnuo TC-80N3a
Observing Notes:
I wanted to include some foreground lighting but the trade-off was a low ISO setting and picking out fewer stars.

The two brightest trails (upper centre) are the Pointers, Alpha and Beta Centauri.
