I so like this short video, kudos to the producer. Over the years I’ve taken many pictures of my own expeditions and found still shots rarely capture the essence of the experience. It takes video and a soundtrack to express it. But what the hell is going on in this video?!

We start indoors with a telescope, then someone that appears anxious, someone is working at a computer and a telescope mount is seen slewing. This is the planning stage, perhaps the final test and preparation stage before leaving. In this case the expedition will attempt to photograph asteroid 2012 DA14 as it flies close by Earth. They will only get one shot at this. It appears they have developed a custom program to move the telescope mount to follow the asteroids path. A challenging task as mounts are not made to do this, hard to simulate this motion ahead of time.

We cut to the waxing moon and all the activity taking place in the field. Equipment is setup and aligned, tested, checked again and shared with others around. If something breaks or fails to work as planned you hope spare parts or a friend can help. Otherwise your mission will fail. I’ll note there is a whole bunch of white light around, there would be howls of protest from the star party light Nazi’s I’ve known.

Around the two minute mark we see the fruits of their labor, it appears they were able to image the asteroid and track it reasonably well. Seventeen seconds later in the video they are packing up to head home. I’m going to bet they were a happy bunch!

All this is speculation on my part, I don’t know this group of astronomy enthusiasts. But I do know what its like to plan a trip, chart my target, fret over the weather and finally be under the night sky to implement my plan. Successfully completing a quest is exhilarating.
