ZWO


Version

 

The NEW 5V ZWO EAF (Electronic Automatic Focuser) is a precise motor focuser that is essential for planetary and deep-sky astrophotography. This updated version removes the 12V power supply port and lets you connect it directly to your camera, laptop or ASIAIR Pro via the USB 2.0 port, making cable management much easier.

It is ASCOM and INDI compatible, allowing to use it with third party software for the automatic focusing (frame and focus). It can be used in combination with the ASIAIR device and the ASICAP software.

The advanced version includes a temperature sensor and a hand controller for manual focusing. The sensor is used to calculate the change of temperature of the tube and consequently its focus shrinkage. The hand controller has two speeds and it is particularly useful for visual observations or during the complex focusing procedure in high resolution imaging of planets.

The EAF is compatible with several telescopes:

  • SkyWatcher Black Diamond, Evostar, Esprit (100mm to 150mm) and Quattro (refractors and Newtons)
  • SharpStar
  • TS Optics
  • Astro Tech
  • Feather Touch

With the optional brackets for Takahashi telescopes, the EAF can be installed on more instruments:

  • Takahashi FSQ85
  • Takahashi FSQ106
  • Takahashi TOA-130NFB
  • Takahashi TOA-150B
  • Vixen VC200L
  • Orion ED80T

Must have for sharp images

Works really well with ASIAIR to focus Espirit 100ED. Essential for good focus avoiding slippage out of focus with weight on focus mechanism. Also allows automatic refocusing during imaging session. Very good price and well made

EAF just works!

This is my second EAF to compliment my second rig.
I love the simplicity of using the focuser with my ASI air plus on my tablet and would thoroughly recommend this product

An essential piece of gear in your astrophotography arsenal

This nice computer-controlled focuser has been around for some years, now, and it has been getting good reviews from just about everywhere. It is well supported with an ASCOM driver for Windows based applications, and it just connects natively to ZWO's ASIStudio and ASiair. If you want to do astrophotography, then it is a must for getting those pin-sharp stars and maintaining them automatically. I have installed one on each of my telescopes, and have not regretted the expense. It has been a breeze to fit it to refractors of various persuasions, and ZWO have detailed examples on its Web site to help you. For its price, it's a winner!

Highly recommended.

Always fast dispatch with Testar. Arrived interstate within two days of ordering. The unit was easy to install on my SVX102T and works perfectly with the ASIAIR. Highly recommended!

ZWO EAF

Great little focuser. I have two of them. One permanently mounted on the Askar 300FRA Pro and a second one connected to my Rokinon 135mm F2 lens via the Astrodynium rings and adapters. It focuses perfectly using the AsiAir Plus.
