ZWO FF110 APO
Flat-Field Apochromatic Refractor
Main Features
Flexible Connectivity for Multiple Configurations
Four-Element Optical Design
The FF110 APO features a four-element, fully air-spaced apochromatic optical design. All four elements work together to deliver a flat imaging field without the need for an additional field flattener.
One ED (extra-low dispersion) glass element is incorporated to effectively reduce chromatic aberration, resulting in improved color correction and image clarity.
44 mm Image Circle — Full-Frame Support
With a 44 mm image circle, the FF110 APO fully supports full-frame sensors and a wide range of imaging setups.
It delivers sharp star fields with excellent edge-to-edge performance, ensuring consistent image quality across the entire frame.
Native Flat-Field Design
The FF110 APO features a native flat-field optical design, eliminating the need for an additional field flattener.
No complex back focus calculations or spacing adjustments are required—simply attach your imaging setup and start capturing once focus is achieved.
Convenient Design
Equipped with a rigid 3-inch rack-and-pinion focuser, the FF110 APO offers precise control with a 1:10 coarse & fine focus adjustment mechanism.
A built-in 360° rotator at the rear allows for smooth and accurate camera angle adjustments.
Retractable Dew Shield & Quick Release Mounting Rings
The FF110 APO features a retractable dew shield, reducing overall length for improved portability.
Precision CNC machining and a high-quality painted finish, combined with an internal anti-reflection coating, help minimize stray light and enhance image contrast.
The mounting rings are detachable, allowing for quick and easy setup or teardown of the telescope.
Photography Extension Tube
The FF110 APO includes a photography extension tube with a 2-inch filter thread, along with rear adapters in M48×0.75 and M54×0.75 standards.
This allows for easy integration with a wide range of imaging accessories.
