I came from an OnStep mount to a Gemini-2.??
While the mount I was using with OnStep was a very cheap EQ3-class mount, I'm finding the Gemini-2 is better in most ways.? The ASCOM driver is far more stable.? I'm seeing far better pointing accuracy and correct me if I'm wrong, but the Gemini-2 system allows the pointing model to be refined by adding additional stars to the model after the initial alignment.? OnStep doesn't seem to allow that, as I asked that question to the OnStep group (and ended up finding my answer in the source code):??https://onstep.groups.io/g/main/topic/82448650#33088
Advantages of OnStep:? cheap.? Good for tinkers but steer clear if you don't like to tinker.? Less concerns around long-term support since the system is open source (but *not* the ASCOM driver!).? And integration with an Android phone app (though it is glitchy as communication issues completely freeze up the UI!!).??
