The Great Telescope of Birr Castle: How a 19th-Century Irish Family Changed Astronomy Audiovisual Science

For over 70 years, the largest telescope in the world was to be found in rural Ireland. Years of effort culminated in a night in the spring of 1845. That's when William Parsons, third Earl of Rosse, gazed into the eyepiece of his 72-inch-diameter Leviathan and glimpsed the spiral arms of distant galaxies. The remarkable scientists, inventors, and artists of the Parsons clan may seem the stuff of steampunk, but Bill Higgins-- fresh from a pilgrimage to Birr Castle-- will assure you that they were quite real.
