Update (January 2016): I have recently built an Arduino-based stepper motor controller. For inquiries, kindly leave a comment below or send an email to email@example.com.
This Kenko NES tracking mount is classified as an EQ3 mount. I got this mount from a surplus shop in relatively good condition but without the motor controller and counterweights, and sold “as is” with no assurance that the motor will work since it is already 2 decades old (1990 model)! In any case, this particular model is made in Japan, the sole reason and my motivation for considering it.
I had to build a stepper controller from scratch (I would have wanted to purchase one, but I could no longer find it on the Internet, perhaps it was already phased-out). Recent upgrades in my DIY controller has given this mount autoguiding capabilities.
Since May 2011, I have been using this mount in my imaging setup and I am more than happy with its performance.
