Lunar Eclipse Dec 2011: Threading the Needle on the Transamerica Pyramid!

Predicting exactly where to stand to have the moon strike the top of the Transamerica Pyramid in San Francisco.
Each second of video translates into 2 minutes of time, so the 5 seconds of video represents 10 minutes of moon movement. Using eclipse predictions, lunar elevation angle and compass direction, I used the height of the tower to predict how far away I’d need to stand and in what compass direction. I mapped that point on Google Earth, showed up a little early to start shooting 120+ photos to created the timelapse sequence, and it turned out that I pretty much nailed it! The center of the moon passed right across the tip of the tower.
