Hunting for extremely dim galaxies is especially difficult with single-lens telescopes. That's because, no matter how technologically advanced, the device's design cannot fully eliminate detail-obscuring scattered light from the resulting images. The University of Toronto's Dragonfly Telephoto Array, however, deftly avoids that issue. This array -- one of the smallest multi-lens astronomy telescopes in use today -- is comprised of 10 Canon 400mm f/2.8 L IS II USM telephoto lenses, each costing $10,000. What's more, each lens is coated in a unique subwavelength nanomaterial that drastically reduces light reflection within the optic. And, like its insect inspiration, the Dragonfly's ten eyes can work in concert with one another to further reduce unwanted illumination in the resulting image, bringing out otherwise unseen detail in cosmic structures. According to the University of Toronto spokesman Roberto Abraham, this $100,000 system is ten times as accurate as its nearest rival.
