As I understand it, only Alnitak flat boxes are supported by SGP and there is no ASCOM standard for flat boxes. I have a flat panel that works very well for me and is a tiny fraction of the cost of an Alnitak box, which is appreciable since I have a 14" scope. What I would like to do is build an Arduino-based controller for my flat panel that would consist simply of on/off and brightness settings. I have my “park” position set such that the scope points directly at the flat panel and I would like it to simulate an Alnitak controller so SGP can control it remotely. I am assuming that SGP uses a serial command set to communicate with the Alnitak boxes, but I have no idea what that command set is. Does anyone know?
