Aurora Borealis Panorama
This is a panorama of 9 images in portrait orientation, taken with my 50 mm f/1.4 wide open, each 8 seconds long at ISO 1250. I stitched them together in Photoshop and then used NIK Dfine to clean up the high-iso noise a bit. Unfortunately, it was quite windy, so the trees are fairly blurry. It works out to about 66.4 megapixels!
