ZWO FF107 APO OTA

 The ZWO FF series is a potential fit for your astro-photography needs.

The ZWO FF107 APO is a finely crafted, high-performance apochromatic refractor designed for astrophotographers and visual observers seeking top-tier optical performance in a compact, user-friendly package. Featuring a 107mm f/7 quadruplet optical system with a dedicated field flattener, this refractor delivers sharp, distortion-free images across the entire field of view, making it an excellent choice for deep-sky imaging and high-resolution planetary work.

Unlike traditional refractors that require additional corrective optics, the FF107 APO is designed with an integrated field flattener, ensuring a perfectly flat imaging plane without the need for extra accessories. This means astrophotographers can achieve pinpoint stars from edge to edge, making the telescope ideal for wide-field imaging with full-frame and APS-C cameras.

Precision Optics for Astrophotography and Visual Use

At the heart of the FF107 APO is a meticulously designed quadruplet optical system with two pieces of ED (extra-low dispersion) glass, which dramatically reduces chromatic aberration and enhances contrast. Whether you're capturing the delicate details of a nebula or the fine structure of a distant galaxy, the FF107 APO ensures images remain crisp and color-accurate with minimal fringing.

The built-in field flattener is optimized for a 44mm image circle, allowing full-frame astrophotography with excellent edge-to-edge star sharpness. Unlike triplet designs that often require external field flatteners, the FF107’s optical system is already tuned for modern astrophotography, providing a streamlined setup for deep-sky imaging.

Built for Precision and Ease of Use

The FF107 APO is constructed from high-quality CNC-machined aluminum, ensuring both durability and thermal stability. The optical tube is compact yet robust, making it an excellent travel-friendly option for astrophotographers who want to take their imaging sessions to dark-sky locations.

A 3.4-inch dual-speed rack-and-pinion focuser provides smooth and precise focusing, critical for capturing sharp images with high-resolution sensors. The 10:1 fine adjustment allows for ultra-precise focusing, even at high magnifications or with heavy imaging payloads. The large drawtube and rotatable focuser design support a wide range of imaging accessories, from DSLR cameras to dedicated cooled astronomy cameras.

Optimized for Astrophotography

With a focal ratio of f/7, the FF107 APO strikes the perfect balance between light-gathering ability and resolution. The flat-field optics ensure that coma, field curvature, and astigmatism are minimized across the entire 44mm image circle, making it an excellent choice for wide-field deep-sky astrophotography.

The telescope is designed to be highly adaptable, featuring multiple mounting options and compatibility with standard astrophotography accessories. Whether you're shooting with a color or monochrome camera, the FF107 APO delivers outstanding image quality without the need for additional optical correction.
