SUMMARY
The forum discussion centers on the photography of the Space Shuttle Atlantis as it transits in front of the Sun, captured using a Takahashi TOA-130 refractor telescope with a Baader solar prism. The images were taken with a Canon 5D camera set to ISO 100 and a shutter speed of 1/8000 seconds. Participants clarify that while the Sun appears significantly larger than the Shuttle due to their respective distances and sizes, the Shuttle is only a few arcseconds across at its operational altitude of over 500 km. Additionally, the conversation touches on the nature of images of the Milky Way, emphasizing that while photos of its central core exist, no real photographs of the entire galaxy can be captured from within it.
