Yeah balancing the Mach 2 has been a breeze. I will get the 12.5 ready and test it out and see how it does. It is a truss design, I can leave the shroud off if you think that will help out.

Weight makes for larger moment, which makes the mount slower to respond to external disturbance, like wind. If your scope is open tube with no shroud, wind will not be a problem.
I will be loading my Mach2 with a 12" F8 carbon fiber Maksutov astrograph in the next couple days. Weight is about the same as your system. I expect that it will handle it fine and will post some guiding results. Will be getting ready for
galaxy season.

What say ye?
46lbs, but would need to add focuser (8lbs), TCS System (1lb), and camera/accessories (call these 5 lbs). The OTA is about 18" tall (maybe 17.5" but lets call it 18") so this puts me at 18" and 60 lbs. This puts me right on the yellow on the Mach 2 graph AP
has. Length of everything, in focus with camera gear on would be about 45".
Seems right at the limits, but likely safe. Any ideas on this from AP or others?
