300-foot’s Balancing Act

The 300-foot telescope in Green Bank, West Virginia was a transit telescope, meaning that it could only lift and dip, not spin around on its base. In this photo, the 300-foot impressively poses at an angle, showing off how well balanced it was on its semi-circle gear. Its first control building is under construction beneath it.
