Does AstroPlanner support the Takahashi Temma mount?
No. The protocol used by this mount is quite arcane and the documentation is not easy to interpret, since it’s only available in Japanese. Also, we don’t have such a mount available to perform testing on. If at some future point more complete documentation becomes available and a beta tester becomes available with access to such a mount, then it is quite possible support will be added. AstroPlanner V2 will enable ASCOM connectivity to Temma mounts on Windows.
