The 90FL model was the top rank, high-end BORG telescope until the 107FL model was released. The 90FL 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 wild birds.
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. You can convert this telescope to a tele lens by swapping the prism and eyepiece with a BORG camera mount adapter (sold separately).
