That's amazing. Is the aurora that bright to the naked eye or does the 30sec exposure help bring out the brightness of the greens etc? When I was in Iceland last year we saw the tiniest smidgen of the aurora on the horizon and I took a pretty long shot which brought it out a bit. (see below). Just interested to know if it's that spectacular in person. It looks amazing.
