But the H2H mounts are really hard to come by for large dishes.That said, this is one of the reasons why I decided against a PM. At extremes, the pulse count is reduced per degree and the whole thing becomes unstable and wobbly. I considered getting a PM from SSS for my CM but having spoken to Dave, the arc would be around +/- 50 degrees - nowhere near enough where I can get to 53E at one end and unlimited to the west (but realistically need 58W at least).
