2016_10_13_Aurora (ex-CME) 3
Slightly weird aurora tonight - started off quite early at about 1940hrs. Washed out against a 92% full Moon - initally a single arc with some rays at about 15 degrees and then a second very high arc formed at about 45 degrees.
It was actually difficult to get both arcs in the same frame on a 14mm lens.
It was however a pleasure to meet someone Ive only chatted to online - Tyler Collins! He was also out chasing the aurora!
Samyang 24mm f/1.4 at f/2
