Canon EOS 5D Mark III DSLR, Sigma EX DG 20 mm lens, Manfrotto tripod. 2 x 1/2 second exposures (stitched) @ f/3.2, ISO-400.
On the night of June 18-19 there was a very bright and expansive display of noctilucent clouds: the best I’ve seen in a long time. I’ve been observing and photographing this beautiful phenomena for 12 years now.
