I discovered that the aurora moves very rapidly when overhead. Quite
fascinating. I saw a display here a couple weeks ago that were from
horizon to horizon, north to south, east to west. They were moving so
fast that a five second exposure would have been on the outer limit of
acceptability. It was the first time I've ever seen them like that.
That's why I suggested a wider lens. Some displays are significantly wider than FF 24 mm. And because they sometimes
change rapidly, the panorama solution may not work.
OTOH, Ctein went to Yellowknife Oct/16 and was, happy with the Panny 12/1.4 and made no comments about wishing for
something wider. So his wonderful aurorae didn't cause those sorts of trouble.
