Great focuser

This focuser is one of the best. Works straight out of the USB power so no need for an external power supply. It has a lot of torque at very little backslash and I was able to mount it easily on my william optics focuser. I am very happy with this purchase and the fast shipping by Telescopes Canada.

Works very well so far

Excellent focuser. It took me 10 min to install on a Stallarvue 2.5 inch focuser. The backwash is in acceptable range. The focuser works with both N.I.N.A. (ASCOM) and INDI.

EAF worked great when new

This device worked very well when it was new on my Sharpstar 94EDPH. After about two years of occasional use the gears of the stepper motor system are shot (huge backlash making accurate focus impossible). It is beyond warranty so I will have to replace it. I am kind of disappointed in the quality.

Compared to its old version, the main change of 5V EAF 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.

The casing of the hand controller uses environment-friendly ABS material.  It has a 3.5mm female socket. You will have a very comfort grip when you touch its ergonomic design!

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!
