Here's the Big Mak on its A-P 1200 mount. It made the trip to PHX without any issues. Customs did not even open the crate.
It brought with it an unusual sky for Arizona, high altitude humidity which manifests itself with jet contrails that grow into high cirrus clouds.
Not totally de-bugged yet. I've determined collimation will take two people. One to look through the scope and one to make the adjustments. The scope is large, so I look at the difraction pattern, step up on a small ladder and make a tweak, climb down and look and I find I made it in the wrong direction.
Also have some small orthogonality issues with the mount. The FOV is small with the 4,000mm focal length, so it needs to be right. I made the holes in the mount plate somewhat large, so we would not have a problem when bolting up the scope. Now I just need to find the right size hammer to tap it into place ;-)
Will have more to say when fully commissioned.
