Yesterday I received my highly-anticipated Nexus DSC and encoder kit for GSOs dobs. I immediately set about installation. I hit a snag fairly quickly on putting the central pivot bolt in the base, and I thought maybe the base had changed since the kit was designed. I sent an email off to Astro Devices and went to work on other things.
Imagine my surprise 5 minutes later when my phone rang, and it was Serge from Astro Devices! He knew exactly what my misunderstanding was, and then proceeded to make sure the other steps were all clear. I was able to continue on and install the encoders in about 30 minutes, getting the system completely set up in way less time than I had expected! I had heard Nexus had good support, but that was unreal.
By the way, installation of the Astro Devices encoders on a GSO dob like my Zhumell Z8 is extremely easy. The impact is very low, with no exposed fragile parts. I'm very happy with the setup.
