The true beauty of orbital mechanics is that since
So here are some nice Lunar transit shots complete with a commentary on tools and techniques. The nice thing about Lunar transits is that all you need are some binoculars or a small telescope to enjoy them, and access to the Internet to know when they are coming up. (The solar transits warrant a little more caution due to the risk of blindness and damage to telescope optics if proper filters are not used to image the sun.)
The International Space Station's new solar arrays are clearly visible in this video image montage taken by Ed Morana a few days ago through a 10 inch Mead LX200-GPS telescope. (Original link from Space Weather.)
Here’s how he did it (from Ed's site):
General Observing procedures:
First, theISS Transit prediction is first obtained using Thomas Fly's ISS Transit Alert Service.
Then, a few hours before the predicted transit event, download the latest ISS orbital elements from the NASA Spaceflight web site and Space-Track.org.
Then load the elements closest to the prediction time into Sky Map Pro.
Then print out a map which provides details of the transit, including Altitude & Azimuth, direction of ISS, time of transit and CCD Field of View.
