International Space Station in H-Alpha

Ever since I made the images and video of the ISS solar transit at Huntsville State Park, I have wanted to do the same thing using an H-Alpha solar telescope. The right combination of location, weather, and available time came together on May 6, 2018, so I borrowed a Coronado PST and headed to Davy Crockett Memorial Park in Crockett, Texas.

The transit occurred at 11:27:44 AM, and lasted about six tenths of a second. Considering it took nearly an hour to drive to the site and then almost a half hour to set up, this seemed like a small reward for the effort. But, it was very satisfying to see the space station race across the face of the Sun literally seconds after I had finished setting up and focusing the scope.
