The telescope that discovered Pluto

This is the telescope that was used in a sky survey, resulting in the discovery of Pluto. The black box in the center, bottom, held large sheets of film.

 

Photographed at Lowell Observatory, Flagstaff, AZ using a Nikon 1 V2, 10mm f/2.8 lens at 1/25 second. This room was very dimly lit.
