The following set of images were taken with a disposable film camera because digital cameras are not allowed near the radio telescopes (especially, the GBT) due to the camera's radio frequency interference. The quality of the images is noticeably poorer!
This is the receiver mast as seen from the ground next to the Green Bank Telescope. You can see the sub-reflector at the top and the underside of a portion of the main dish to the right.
