Mars with the moon behind a tree:
20 seconds, f/11 with a 12mm lens on my new Nikon D100. Although the Canon won the noise testing (as Eric and Brian and all the reviews implied), the lenses, features and ergonomics of the Nikon won my heart... er, pocketbook. I did like the silky images from the Canon, but look at the above shot. It's orders of magnitude less noisy than the 950, and at ISO 1600 to boot!
