Sequence of consecutive images captured over 23 minutes and used to generate a star trails image using StarStax software.

Tripod mounted Canon 760D DSLR and Sigma 10-20mm lens at 10mm (16mm equiv) focal length. ISO 6400, f/3.5 and 30s exposures. Cairns lit by LED light panel located approx. 40m away.

Interestingly the long entrance corridors to this burial cairn align very closely with due east.
