Overview

The 80 mm Apochromatic Astrograph from ZWO

This 80 mm apochromatic astrograph refractor from ZWO features a 4-element, 3+1 air spaced quadruplet lens design. Two lenses are made of extra-low dispersion (ED) glass to minimize chromatic and other aberrations. Its self-flattening design provides a flat field for imaging without the need of an additional field flattener accessory. Multiple included adapters give versatility to connecting a variety of cameras and other accessories to the scope. Finally, the 44 mm image circle supports full-frame camera sensors, for a larger field of view.

An Astrograph Worthy of the ZWO Name

This 80 mm apochromatic refractor from ZWO has some great specifications. An 80 mm aperture and 600 mm focal length produces a focal ratio of f/7.5 for this system. The large 3″ dual-speed, rack-and-pinion focuser provides 1:10 fine adjustment.

In addition, the whole system is lightweight. The optical tube weighs less than nine pounds, while the tube and included accessories together weigh just slightly over ten pounds!

High Quality Optics in a Quadruplet Design
The ZWO FF80 apochromatic refractor features a 4-element, quadruplet design. Two of the lenses are made of extra-low dispersion (ED) glass to minimize chromatic and other aberrations. The lenses are in a configuration that naturally flattens the field, making a separate field flattener accessory unnecessary.

Many Strong Features for Astrophotography
This astrograph from ZWO has many features that make it great for astrophotography. A 44 mm image circle supports full-frame camera sensors. The central RMS radius is 3um. Included are four camera adapters (sized M48, M54, M68, and M76) that allow for connecting a variety of cameras and accessories. The M48 adapter also has an internal female thread for attaching 2″ filters. Also included is a 360-degree rotator, which allows for rotating an attached camera or accessory to the user’s desired orientation.

Tube Rings, Dovetail, and Other Added Features
Also included with this 80 mm quadruplet refractor are tube rings with an integrated carrying handle, a Vixen-style dovetail plate, and a retractable dew shield. The large 3″ dual-speed (1:10) rack-and-pinion focuser supports both fine and course adjustment and is compatible with the ZWO Electric Automatic Focuser (EAF) without the need for an additional adapter.
