The BORG 90FL CR has exceptional optical resolution, accomplished by apochromat fluorite glass elements from Canon Optron, Inc. built in the optical design of the objective lens, and a super tele 500mm focal length and aperture of f/5.6.
A great piece of gear for observing celestial bodies and bird life in the Australian bush and city environments.
The 90mm front element diameter does not hamper the 90FL's extreme compact and lightweight capabilities thanks to the detachable carbon fiber made barrel. Recommended for starry sky, nebula, star cluster, and planet observation.
