Taken within days of Mars' historic rendezvous with Earth in August of 2003, within weeks of getting my C8-NGT, and long before I knew what the heck I was doing. It was rather cool of Jon to let me borrow his D100 to get this shot. Mars' North is up.

Image Description:

This is a hurried but nonetheless pleasing shot of the sun setting over the Pacific. This is shot roughly toward Half Moon Bay, which had clearly been socked in by the Marine Layer along with most of the rest of the San Francisco Bay Area. This was one of the first shots I captured before the “main event,” which was this shot of Mercury and the Moon setting together over the Pacific. See the writeup on that image for more information on the location from which this is shot. A higher resolution image is also available. Celestial North is as indicated on the mouse-over. Sunset was at a compass heading of WNW that evening.
