The BORG 107FL Telescope Set CR is the premium model BORG telescope, designed for professional astro-watchers. This telescope features a 600mm focal length objective lens that incorporates high-end apochromat fluorite glass elements from Canon Optron, Inc.

Axial chromatic aberrations are suppressed even further with the 107FL objective lens when matched against the 90FL. The BORG 107FL Telescope Set CR is constructed with a lightweight and compactable carbon fiber barrel. Arca-Swiss Quick Release base plates are included for tripod mounting. The BORG 107FL Telescope Set CR is recommended for starry sky, nebula, star cluster, and planet observation.

You can convert this telescope to tele lens by swapping the prism and eyepiece with a BORG camera mount adapter (sold separately).

Main Features

• Fluorite glass elements from Canon Optron, Inc. are incorporated in the optical design for ultimate resolution and minimal axial chromatic aberrations.
• Objective lens optical construction: 2 elements in 2 groups, fluorite apochromat, fully multicoated.
• Robust and beautiful carbon fiber barrel.
• BORG 80Ø barrel system.
• Rack & pinion focusing system.
• Erect prism (included) allows users to observe both on-ground objects and celestial bodies.
• 20mm and 9mm eyepieces included.
• Super lightweight at 3.7 kilograms (including accessories).
• Arca-Swiss Quick Release System tripod plate.
• Objective lenses and major parts are Made in Japan.

'CR' stands for carbon fiber barrel and rack & pinion focusing system.

Camera mount adapters and other camera components are sold separately.

M57 DXII helicoid focus unit

The reducer (7880) reduces the focal length from 250mm to 200mm, brightens the aperture from f/4.5 to f/3.6, and improves image quality from corner to corner, including coma aberrations and light fall-off performance.

Great performance is achieved by incorporating Canon Optron, Inc. fluorite glass elements in the optical construction. The precise built quality results in an extremely sharp image with less chromatic aberrations compared to low dispersion (ED) lenses.

You can convert this tele lens to a telescope by attaching a BORG telescope prism and eyepiece (sold separately).

Main Features:

• 55FL Tele Lens and Reducer (7880) set.
• Objective lens incorporates Canon Optron, Inc. fluorite glass elements.
• Objective lens optical design: 5 elements in 6 groups, fluorite element, apochromat, fully multicoated.
• BORG 60Ø barrel system
• Set includes a M57 Helicoid DXII (7761) for subtle focusing.
• Ultra-lightweight of 637 grams.
• Light enough to load onto portable start trackers.
• Objective lenses and major parts are Made in Japan.

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. You can convert this telescope to a tele lens by swapping the prism and eyepiece with a BORG camera mount adapter (sold separately).
