I took this one in November at Wiruna--a difficult one to process as it turned out. Probably too short an exposure.

NGC 1808 is a Seyfert galaxy located in the constellation Columba. The galaxy has an unusual warped shape. Most spiral galaxies are flat disks, but this one has curls of dust and gas at its outer spiral arms (upper right-hand corner and lower left-hand corner). This peculiar shape is evidence that NGC 1808 may have had a close interaction with another nearby galaxy NGC 1792 ( not in the picture)
