Observatory telescopes with the Milky Way in the night sky seen through the observatory's retractable roof, as seen with a full-dome fish-eye lens. This is the Cumeada Observatory, in the Alqueva Dark Sky Reserve, Portugal. The Milky Way is our galaxy seen from the inside, forming a band of stars and nebulae stretching across the sky. Photographed in 2019, after the observatory was rebuilt and expanded that year.
