The 46 metre radio telescope at the Algonquin Radio Observatory. The dish can rotate through a full 360 degrees horizontally (azimuth) and 90 degrees vertically (zenith). The control room is in the building just visible at the right hand edge of the photo. The clean white area on the dish surface is a newly painted test area. Thoth Technology, the current operators of the site, are undertaking an extensive restoration project to bring the equipment back to pristine condition.
