ZWO has released a new 3-inch FF80APO 0.76X full frame reducer with a three-element optical design, including one element made of ED glass. Its reduction factor is 0.76x, which gives the FF80APO f/7.5 astrograph a shortened focal ratio of f/5.7 and a shorter focal length of 312mm. This allows for less total integration time and a wider field of view, bringing more convenience and possibilities for your wide-field deep sky imaging.

The reducer has a rear interface that attaches to the FF80APO telescope tubes included four-segment camera extension tube. The back focus is the standard 55mm, and it has a built-in M48X0.75 2-inch filter thread for easy attachment.

Connection steps:

1. Prepare the FF80APO telescope tube and the focal reducer.
2. Unscrew the four-segment connector at the end of the FF80APO telescope tube.
3. Unscrew the end cap of the 0.76X reducer and attach it to the M68 thread of the four-segment connector.
4. Unscrew the front cap of the reducer, insert it into the focuser inner tube, and tighten it.

Introducing the New ZWO EAF 5V , this electronic focuser, like its previous version, enables precise, dynamic focus control for planetary and deep-sky imaging, while only connected with 5V USB.

No more need for independent 12v Power when it can run from a USB power source.

Features:

1. Highly integrated design
2. Support ASCOM platform and various ASCOM-compatible third-party software
3. Support INDI
4. Support original software such as ASIAIR and ASIStudio
5. Support automatic focusing for DSO imaging
6. Support handle controller and manual focusing
7. Support temperature sensor
8. USB HID device and drive-free
9. Stable and durable

Compared to its old version, the main change of ZWO EAF V5 is to remove the 12V power supply port. Now you can directly connect it to your camera, laptop or ASIAIR PRO via the USB 2.0 port & cable for both data transmission and power supply. This would not only make the cable management much easier, also effectively reduce the supply pressure.

The innovative decorative pattern on the EAF is inspired by the changes of Airy disk during focusing and the focusing curve, which makes it clear at a glance how this focuser works.

There are two variants of the ZWO EAF V5:

Advanced Version: EAF body, flexible coupling, motor bracket, USB2.0 cable, hand controller, temperature sensor.

The hand controller provides an easy method of focusing the telescope, featuring IN and OUT buttons, a 2-line display, slow and fast speed rate control.

A “must-have” option for EAF users!

ZWO has released a new 3-inch 0.7× full frame reducer that is compatible with the FF107APO and FF130APO telescopes. It has a three-element optical design, including one element made of ED glass. Its reduction factor is 0.7, which gives the FF107APO a shortened focal ratio of f/4.9 and a shorter focal length of 524mm. This allows for less total integration time and a wider field of view, bringing more convenience and possibilities for your wide-field deep sky imaging.

The reducer has a standard 55mm back focus and comes with M68, M54, and M48 threaded adapters for easy attachment.

Connection steps:

1. Prepare the FF107APO/FF130APO telescope tube and the focal reducer.
2. Unscrew the M86 to 2-inch adapter at the end of the FF107APO telescope tube.
3. Unscrew the end cap of the 0.7X reducer.
4. Insert the reducer into the focuser inner tube and tighten it.
