This is a photo of the space shuttle Atlantis traveling across the path of the sun that I happened upon whilst cleaning up my favorites, the best silhouette I have ever seen.
Transit duration: 0.8s. Transit bandwidth on Earth: 5.6 km. Altitude: 600 km. Speed: 7 km/s (25000 km/h). Length of Atlantis : 35m, length of Hubble : 13m.
Takahashi TOA-130 refractor (diameter 130mm, final focal 2200mm or 3400mm) on Manfrotto video tripod, Baader solar prism and Canon 5D mark II, plus a detailed map of Florida, a GPS (for the precise location) and a radio-controlled watch (for the precise time). Exposure of 1/8000s at 100 ISO (RAW). The ships being too small and too fast to be watched through the viewfinder, a "blind" series of 16 images (at a pace of 4 images/s) starts 2 seconds before the predicted time.

This picture has been in my head for weeks. Like a song, but in picture form.
