APO 107/749 FF107 Refractor Telescope

The ZWO FF107 APO is a high-performance quadruple apochromatic refractor designed to meet the most demanding requirements of modern astrophotography without compromising on an excellent visual observation experience. Its advanced four-element optical design, featuring two ultra-low dispersion ED glass elements, provides outstanding chromatic correction and a completely flat, corrected field of view down to 44 mm, ensuring pinpoint stars edge-to-edge without the need for an additional flattener or critical backfocus. With a 107 mm aperture and a focal length of approximately 740 mm (f/7), it offers an ideal balance of resolution, brightness, and field of view, making it particularly versatile for nebulae, galaxies, the Moon, and planets. The telescope is completed with a robust 3.4" rack and pinion focuser with 1:10 reduction and 360° rotation, ensuring precise and stable focusing even with heavy cameras. Made of aluminum using high-precision CNC machining, compact and carefully balanced, the FF107 APO is positioned as a premium optic designed for advanced astrophotographers seeking optical quality, mechanical reliability and professional results from the first use.
