While reading up on techniques for lightning photography, I became aware of a broader range of atmospheric optical phenomena - all of which are interesting to photograph. This site has a good thorough overview of what's out there to see, and some amazing pictures. Check out the ice halos in this fish-eye shot from the south pole. Geometry is magnificent.

New Mexico has amazing sunsets, cloud displays, and clear views of the stars on a regular basis. Hopefully I'll be able to get good pictures of some of these atmospheric optical beauties. Unfortunately, the monsoon season is drawing to a close which means there won't be much lightning around here for about 9 months, and it is so dry here that cirrus clouds just aren't too common.
