Development of the STS Delta Aerospace Voyager Drive System 9 Oct. 2020 

I own and frequently use an Explorer Scientific Twilight I mount and I must say that it is a tremendous value for a rugged Alt/Az telescope mount. I had found that they were no commercially available dual axis motor drive systems for this particular mount so I took it upon myself to design and build a simple and robust motor drive system for this mount.

First and foremost I wanted to build a high quality product using Mil. Spec. and Industrial grade components sourced from vendors located in the United States. I also wanted it to be simple to install and simple to operate even while wearing heavy winter gloves.

I must mention that I recommend for the user of the Astro-Tech/Explorer Scientific Voyager Alt/Az mount and this motor drive system to disassemble the mount head and re-lubricate and reassemble. This will greatly improve the performance of the motor drive system. We have several of these mounts and none of them arrived properly lubricated or tuned.

The design also allows for the best of both worlds, the motor drives can be installed in amanner that will allow for both the use of the stock manual slow motion controls and the motordrives.
