Two Crescents, One Vista
There is nothing quite like seeing a very young crescent Moon in the same vista as the super-bright diamond of Venus. Although this February 26th conjunction shot shows the two planetary bodies close together, it does not convey what I saw. In fact, no photograph can really capture it, since the blazing gem of the cloud-shrouded planet will over-expose itself into a big dot near the Moon with its dim Earthshine. Even HDR cannot help, since a properly-exposed Venus would disappear into a few pixels' worth of image, hardly conveying the brilliance of the Evening Star.
The best we can do is to take two properly-exposed photos and enlarge them. The Moon is about what one would expect for the infant phase, as it dipped into a bit of horizon fog that evening:
But the surprise comes with the enlarged view of Venus. The extra February brightness is coming from a planet that is sporting a relatively thin crescent:
How can this be? Why does Venus get brighter as its crescent gets narrower? The mystery is explained here.
By the way, Venus completes my collection of planetary disks that can be captured with an ordinary telephoto lens. (See the Astrophotography With a Camera and Tripod blog posting.) Someday I plan to make a composite image that shows: The Moon, Venus, Mars, Jupiter with its moons, and Saturn with its rings.
Morning Lunar Aviary
A mid-January winter sunrise can be a magical time, where you can see golden sunlit branches at the same time as the normally-nocturnal moon.
As I was shooting the above photo, my peaceful morning was rudely interrupted by the furious honking of overflying Canadian Geese. Seeing their sunrise-bathed, gracefully aerodynamic bodies caused me to quickly forgive the intrusion, as I swung my camera lens in their direction.

January Volcano
In mid-January, Kathy and I took a day trip to Mt. St. Helens. (Or at least, as close as we could get before being stopped by snowy road closures.) After driving through miles of icy fog, we suddenly broke out into warm and beautiful sunshine with Mt. St. Helens presiding over the post-eruption landscape.
