The Dragonfly Telephoto Array, a robotic imaging system optimised for the detection of extended ultra-low surface brightness structures. The array consists of Canon 400mm f/2.8 L IS II USM telephoto lenses coupled to science-grade commercial CCD cameras. The lenses are mounted on a common framework and are co-aligned to image simultaneously the same position on the sky.
