I set out late at night with this shot in mind, I wasn't expecting to see any cloud.
I set up the Gigapan Pano head with not much hope as the cloud was rapidly approaching.
When I got back to the PC and stitched this panorama I was pleasantly surprised- the cloud had added to the image.
Taken as the Milky Way was setting to the west, there's even a faint Aurora glow to the South
