EAF-Quattro EAF Mounting Bracket

Starizona EAF-Quattro is an electronic focuser that allows precise control of your telescope's focus. It is compatible with both versions of the Skywatcher Quattro focuser and includes two sets of mounting screws. The EAF-Quattro is easy to install and comes with several different shaft couplers to ensure compatibility with your telescope. It also features a recessed cutout to prevent the coupler from touching the focuser body. With its precise control and easy installation, the EAF-Quattro is the perfect accessory for astrophotographers who want to achieve perfect focus.

Starizona Mounting Bracket

for ZWO EAF and Skywatcher Quattro

There are two versions of the Quattro focuser depending on the telescope model. This

mounting bracket works with both and includes two sets of mounting screws, one for each

type of focuser. The installation instructions are basically the same for both versions.

1. Remove Focus Knob

Begin by removing the left side knob from the focuser. There is a single set screw that is

accessed through a hole in the black pinion block of the focuser. Loosen this screw and the

knob will slide off the focus shaft.

2. Remove Mounting Screws

Remove the left two mounting screws from the black pinion block of the focuser. These will

be replaced by the longer screws included with the mounting bracket.

3. Install the EAF Shaft Coupler

The ZWO EAF includes several different shaft couplers, and for the Quattro you will use the

one with a 4mm hole on one side. Note that the coupler should slide on until you can

tighten the lock screw just outside the focuser pinion block. Do not slide the coupler all

the way into the hole that the focus knob came out of.

4. Install EAF Motor

This step differs slightly depending on the focuser version. One version has a tapered white

section above the top side of the black pinion block while the other does not. More of the

top (eyepiece side) of the black pinion block is visible on the latter type.

For the first version, install the EAF motor so the motor end of the shaft coupler is flush

with the face of the EAF. The EAF has a recessed cutout here, so the coupler is still about

1mm from touching that recessed surface. But the coupler should be even with the flat

face of the EAF motor.

For the second type, leave about 2mm between the motor end of the shaft coupler and the

face of the EAF. This allows the screw holes in the mounting plate of the bracket to line up

and also allows the bracket to clear the larger tension knob on this style of focuser.

5. Attach Bracket to EAF Motor

Use the M4 hex screws that come with the EAF to attach the motor to the bracket. The

bracket can still wiggle a bit at thise point before it is secured to the focuser, so you may

not want to completely tighten these screws down until after the next step to make sure

the motor and bracket end up square.

6. Attach Bracket to Focuser

The last step is to attach the bracket to the focuser using the mounting screws included

with the bracket. The smaller M3 screws and washers are used for the first style focuser

described above (first picture below) and the larger M4 screws and washers are for the

second type (second picture below).

After installing the focuser mounting screws, adjust the motor mounting if needed to keep

everything squared up. You are ready to use the EAF on your Quattro. Time to go outside

and wait for the clouds to go away!
