Telescope Technician Nathan Sharp changing a GBT surface panel position

Telescope Technician Nathan Sharp uses this panel adjustment tool to slightly change the position of one of the Green Bank Telescope’s 2004 surface panels. His goal is to get the entire surface shaped into a section of a perfect parabola, so that it will reflect radio waves precisely to a point 200 feet above it, called the prime focus.
