Instructions for use

The FF107 APO is a long-focal-ratio refractive astrograph with a powerful flatfield optical design which saves you from the expensive cost of a field flattener. It eliminates the trouble of calculating the back focus distance of the flattener and connecting various accessories to achieve that distance. You can just connect any possible accessories you need as long as the target is focused. This makes the whole setting up process much more convenient, and saves your time, allowing you to pay more attention to the image shooting itself. It will also be an ideal telescope if you want to do visual astronomy.
Directly connect the star diagonal to the eyepieces,you’ll see focusing is such an easy thing then. Planetary observation in high magnification is also piece of cake!

ZWO FF107 APO, a versatile all-rounder.
FF107 APO can literally be applied in any conceivable situations, and that’s the top reason why FF107 APO is produced: to slash as much trouble for users as possible.
FF107 APO, an f/7 astrograph, contains four pieces of lenses including two pieces of ED glass, which can better reduce chromatic aberration. It can achieve excellent color correction even with the magnification mounting to 300 X in visual observation.

The built-in Flatfield lens is a great contribution to FF107 APO’s imaging ability. It supports 44mm full-frame imaging. The stars around the corner of the images seldom suffer from distortion or deformation. At the center of its field of view, the RMS radius is merely 3um.
Even a fastidious user can also be satiated when it comes to the shape of stars. FF107 APO can effectively handle with problems of field curvature and vignette.

FF107 APO can capture tiny star objects due to its 749mm focal length and astonishing field flattening capacity.
When used FF107 APO and a high-resolution camera, it can still bring out lots of detailed information of your target.

FF107 APO is also a nice choice for your visual observation. It fits 1.25″, 2″ diagonal as well as various eyepieces and can achieve a perfect focus. It can even be used to observe planets with a super-high magnification eyepiece.

The sleek FF107 APO is assembled with high-quality CNC-machined components and wrapped with smooth coating. The calm and seriousness is offset by the bright red decorative rings or knobs. The 3.4″ rigid focuser is capable of handling a load of 8kg. It’s designed with a long travel distance of 95mm, which is suitable for visual observation. And it’s been optimized especially for astrophotography.
