ZWO FF80-APO

The ZWO FF80 APO is a refractive astrograph with the 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, the whole optical system is perfect for imaging. This makes the whole setting up process much more convenient, and saves your time, allowing you to pay more attention to the image itself.

The FF80 APO is also a nice choice for your visual observation. It fits diagonal as well as various eyepieces and can achieve a perfect focus, and can even be used to observe planets with a super-high magnification eyepiece.
The whole design of the telescope is compact and lightweight. The OTA weighs only 3.9kg, and the full package with tube rings and other accessories weighs 4.7kg. It has an aperture of 80mm. The focal ratio is f 7.5 and focal length is 600mm.

The FF80 APO adopts a 3+1 quadruplet lens structure which contains two pieces of ED glass that can effectively reduce chromatic aberration and enhance clarity and sharpness. It supports the full-frame imaging circle and has a fine spot diagram with tiny distortions of the peripherals stars. The 3 rigid focuser comes with a new-type 360 rotator with scales and a finder base. M76, M68, M54 and M48 camera adapters are also attached, and the M48 adapter has a 2 female thread for installing filters.
