Tried my hand at capturing a moving object. This is 2000 QW7, a medium sized asteroid about 1000-2,100 feet across (300 to 650 meters). Discovered in 2000, it is a little bit bigger than the Empire State Building basically. It's been in the news recently because it came relatively close this past Sunday and would make quite a mess if it hit the Earth. Next closest approach will be in 2038.
I wanted to grab a few frames of the asteroid before it zipped back out into the solar system. At closest approach it's about magnitude 14. But it's very low on the horizon where I live (just about 8 degrees altitude at highest point during the night), and there are a lot of trees and power lines in that direction. Not to mention a lot of air mass on top of my usual crappy seeing and the full moon only a few arc minutes away. I played around with a few different exposure times, but didn't realize at the time that it would also affect the animation. That (plus a few dropped frames) are why the asteroid sort speeds up and slows down.
Despite all that, I'm pretty happy how it turned out Looking forward to trying again with a target in a little more friendly position.
