This desert saguaro cactus - a symbol of the US Southwest - appears to be approximately 300 years old (per the guess of a resident).
This is a stack of images - 30 second images at 1000 ISO at f/4 totaling 52 minutes worth of exposures. Focal length is 13mm. There is remarkably little noise in part due to the averaging affect of 104 exposures.
Taken with a Canon 40D. Composited using Digital Photo Professional and StarTrails.exe. The process I use is described on my website.
Illumination provided by a high intensity LED flashlight, a low intensity red LED headlamp, and brake lights of a car nearby. Attempts at filling with a flash failed due to the extremes in distance between the base which was less than 10 feet from the lens and the top most spire which was perhaps 45 feet away.
NOTE: This photo was taken using continuous exposure mode with the camera resting on my backpack - I only brought one tripod.

The reason I went to Washington, DC (other than to visit my father and sisters, that is!) The moon here is in the penumbra (the first phase of the total eclipse) as it sets over the US Capitol building. Above the moon is the statue "Freedom" on top of the US Capitol. I think it's cool that you can see the moonlight streaming through the tholos on which the statue sits.
It will be interesting to see if it is possible to get the moon in just the right spot so that it is directly behind the statute - but Washington, DC is pretty flat and heavily tree (and building) lined, so the working room is pretty small. I was literally standing in the right lane of Pennsylvania Avenue (thankfully there was very little traffic).
Want to do this yourself? My next moon alignment webinar is January 4, 2012. And after that, February 11, 2012.

Burney Falls at Burney-McArthur State Park, California is to my eye one of the most beautiful falls. I rank it above all of the waterfalls in Yosemite for its beauty. Not only are there two primary locations where the water flows over the precipice, but the water seeps out of the porous rock in a large swath of color. That seeping produces many little fall-lets with tantalizing green moss, lichens and ferns. I have no clue what produces that strong aqua band at the base of the fall, but it's yet one more interesting thing.

The International Space Station made an appearance on the first night of meteor hunting for the Geminid Meteor Shower. Another, unidentified satellite also whisks by.
Comet 46P/Wirtanen was in the frame to the left, but I cropped it out.
One thing I did wrong here was not starting my exposure before the ISS entered the frame. But in my defense, I was running a Field Event and was attending to our clients.
