I have a Celestron C90 on an Orion Goto Alt Az mount. Using a raspberry Pi 4 running Astroberry. Two ASI224MC cameras. One camera equipped with a 28mm f1.4 lens for finding and the other camera is attached to the telescope with a focal reducer making the C90 a 500mm. The entire system is mounted on a 6061 aluminum plate mounted on the post of my deck. The system is remote controlled over wifi using the synscan app or from a Celestron handheld remote using a 30 foot ethernet cable.
