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.

 

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

 

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.
