This telescope is actually simply 10 Canon lenses strapped collectively
Looking for extraordinarily dim galaxies is particularly troublesome with single-lens telescopes. That is as a result of, regardless of how technologically superior, the gadget’s design can’t absolutely get rid of element-obscuring scattered mild from the ensuing pictures. The College of Toronto’s Dragonfly Telephoto Array, nevertheless, deftly avoids that problem. This array — one of many smallest multi-lens astronomy telescopes in use right now — is comprised of 10 Canon 400mm f/2.eight L IS II USM telephoto lenses, every costing $10,000. What’s extra, every lens is coated in a singular subwavelength nanomaterial that drastically reduces mild reflection inside the optic. And, like its insect inspiration, the Dragonfly’s ten eyes can work in live performance with each other to additional scale back undesirable illumination within the ensuing picture, bringing out in any other case unseen element in cosmic buildings. Based on the College of Toronto spokesman Roberto Abraham, this $one hundred,000 system is ten occasions as correct as its nearest rival.
