Vixen DD-3 Dual Axis Controller

 from United States– Verified Buyer

I purchased the new Vixen DD3 dual axis driver
controller as a replacement for my DD1
controller. I had some problems with the old
DD1 controller driving Declination motor,though
it really was not an issue. The advantage with
the DD3 is the Autoguiding port and better accuracy. With this i can guide and image at the same time with my Starlight XPress CCD camera or my Canon DSLR. Besides the controller is compatible with my single axis Vixen Photoguider mount as well.

Combined with the precision of the Vixen GPD2 mount and the accuracy of the DD-3 electronics, objects are kept in the field of view leading to less number of bad frames. The recessed power receptacle and the snug fit power connector is a good design change.

I am happy with the purchase of Vixen DD3 controller and would like to say it is a good buy.
