ZWO 107 mm Apochromatic Quadruplet Refractor Optical Tube
For Astro-Imaging or Visual Observing, this ZWO 107 mm Quad is Just the Thing!
Well known for their outstanding astro-imaging cameras, ZWO takes their expertise a step further with this beautiful 107 mm Quadruplet Apochromatic Refractor! Four internal lens elements work together to eradicate chromatic aberration for pristine, crystal clear views and images. These lenses are arranged in a 3+1 structure and feature two pieces of extra-low dispersion (ED) glass for the utmost performance. This produces a flat field so you do not need a stand-alone flattener, which can be expensive! Because there is no need for a flattener, you do not have to worry about calculating its back focal distance in addition to that of the scope and your adapters, making it much easier to add your accessories and start shooting!
As an industry leader in top-tier astronomy equipment, you can expect superb build quality with your ZWO FF107 Quad APO Refactor. The large, heavy duty Rack & Pinion focuser helps you dial in the focus with its two-speed design while also supporting hefty imaging equipment. Other necessities included within this package are a Vixen-style dovetail, multiple rear-end adapters, and cradle rings to secure your telescope in place. The large aperture of this premium refractor acts as a light bucket for beautifully bright sights, and the f/7 focal ratio and long 749 mm focal length is ideal for observing a host of celestial objects. With a sleek, red and white finish, ZWO has you discovering the cosmos in style. Qualities like these make the ZWO 107 mm Quad the perfect solution for those looking to take their astronomy experience to new heights in 2025!

Hefty 3.4" Dual Speed R&P Focuser
The ZWO 107 mm Quad Refractor has a focal length of 749 mm and a focal ratio of f/7. It comes with a heavy-duty 3.4" rack and pinion focuser that offers dual-speed 10:1 focus, a 360-degree rotator with scales, and a finder base (finder sold separately). Focuser travel is 130 mm.
Includes Four Adapters for Easy Camera Connection
The ZWO FF107 supports full frame cameras with an imaging circle of 44 mm. The spot diagram (see images) shows small and round stars, with a central RMS radius of 3 um. Included with the telescope are four different camera adapters (M48 (which accepts 2" filters), M86, M68 and M54). This telescope also works wonderfully well for visual use. It accepts standard diagonals and eyepieces, and has no trouble achieving perfect focus when viewing the universe with your own eyes.
Telescopic Lens Hood for Improved Contrast
The FF107 also includes really nice features like a telescopic lens hood that can be locked down with thumbscrews should you wish to keep it from sliding. You can slide it back against the body for storage and then slide it out to accomplish protection against dew collection as well as contrast reduction due to light glancing off of the optics when you are observing or imaging.
High Functionality Cradle Ring with Handle & Dovetail
A detachable tube ring in beautiful anodized red looks great and matches any ZWO accessories or cameras you may own. The cradle ring is designed to be removed or reattached quickly and easily. The top of the cradle rings sports a handle that can be used for accessory attachment if you wish. If not, it is a handy way to carry your OTA and hold it steady while attaching to your choice of mount. A Vixen-style dovetail plate, also in red, is included. This allows you to connect your FF107 to a wide variety of mounts!
