Q1: Which focusers are supported?
The current EAF bracket is compatible with
- SkyWatcher Astrograph reflectors,
- SkyWatcher Black Diamond,
- SkyWatcher Dobsonians,
- SkyWatcher Maksutov-Newtonians.
- SharpStar Telescopes
- SkyRover Telescopes
- TS Optics
- Astro Tech
- Feather Touch
- Some others such as Explore Scientific will fit with longer screws (not supplied)
- More focusers will be supported in the future as we develop more brackets
Q2: Does the EAF work with single-speed and/or dual-speed focusers?
If the EAF fits, it does not matter if it is on a single or dual-speed focus knob. We recommend attaching to the coarse focus knob, not the fine focus. There are 4 different sized adapters to attach the EAF to the focus shaft.
Q3: Is the EAF suitable for deep space and planetary imaging?
Yes, the EAF works for all types of astrophotography. With the ASCOM driver, you can use the EAF with any ASCOM compatible software or the ASIAIR.
Q4: Does the EAF make a difference?
Yes, the EAF can make very fine adjustments, meaning it is more accurate than manually adjusting focus. The EAF can also keep you in focus all night when using ASCOM drivers (coming soon to ASIAIR).
Q5: What power supply is required for the EAF?
The EAF requires 12V 0.5A. As long as the power supply is 12V and has 0.5A or more, it will power the EAF. The port is 5.5mm*2.1mm centre positive.
Q6: Can I manually adjust the focus from my Computer?
Yes, the ASCOM driver makes the EAF compatible with capture software that supports electronic focusers.
Â
Q7: Is the focus speed variable?
Yes, the EAF can focus at different speeds. On a computer, you can set the number of steps in a single rotation for precise control.
Q8: Do I need to install drivers to use the EAF
For use with the ASIAIR and ZWO’s computer capture software – ASICAP, no drivers are needed, simply plug and play! For use with other software, the ASCOM driver is required, found here: https://astronomy-imaging-camera.com/software-drivers
Â
Q9: Which capture software supports the EAF?
Sequence Generator Pro, Focus Max, The SkyX, Nebulosity, etc. If the software supports electronic autofocus via ASCOM then the EAF will work.
Q10: How does the EAF attach to a telescope?
First, you need to remove the focus knob from the focuser and check which of the 4 supplied adapters fits your focuser the best. Then attach it to the EAF and the focus shaft, then remove the necessary screws from the bottom of your focuser to then screw the bracket in place.
Does the EAF work on an Astrotech 72EDII?

I have the Explore Scientific ED80 Triplet standard (not-CF) and would like to know how to connect the EAF. I saw some information on yuque.com but it is a bit confusing. Which screws do I need and where should they be installed? The only available screws are attaching the focuser to the OTA .

You need the standard EAF motor bracket and buy extra screws: 2 X 19mm M4.

Which screws are these? Are they the focuser tensioning screws? Also, when mounting the EAF this way, do I need to choose “reverse” to have proper in and out movement?

Hello,
I am having some issues getting autofocus to work with my ZWO narrowband filters. The auto focus routines works just fine using the luminance filter, not so much with Ha, Oiii and Sii. Any ideas what could be going on? I’ve used different step sizes and nothing works. I am using NINA to control my focuser.
Thanks,
Tommy

Hi , i bought a Zwo eaf and thought evrything was in the kit , since i am controlling it from my pc i thought it would get Power from that.
There is no info about needing to buy a Power cable in the add , so i asumed it was in the Box , i mean , how much could a Power cable cost compared to the price of the kit?
If it is true that zwo sells this without the Power cable , find it Incredible cheap , they could at least informed about it , but hopefully i’m wrong.

You can see the title “What’s in the box” in this website: https://astronomy-imaging-camera.com/product/zwo-eaf
There is no power cable in the box. Also you can see the title “Connecting diagram”, the picture reminds you connect the power supply.
