It depens on the original orientation, but I'm assuming the Alpha has 320 degrees of over travel. I have mine oriented N at the middle of rotation on the Prosistel so I have 60 degrees of over trave

I'm not defending their tactics and I probably would have purchased differently had they been using them back when I needed a rotator, but I have to say that it is one of the best built rotators I h
