When I strip the scope I will upload some images of the entire kit. You can have the kit, I have no need for it anymore.
I had a place a Loch Rannoch for 6 years and Glencoe for a year. I hope to move back eventually.
I received the following from Serge at Nexus.
In order to be able use Nexus DSC/Nexus/Nexus-II on your telescope you will need an encoder installation kit. Our encoder installation kit (with 10,000 steps encoders) for Obsession 18” UC is priced at US$280. Then you will need either Nexus DSC, Nexus-II or Nexus. The main difference between Nexus DSC and Nexus-II/Nexus is that Nexus DSC can be used standalone or with SkySafari while Nexus-II/Nexus requires SkySafari to operate.
