I found out I have the exact same problem when I tried to mount a ADM vixen dovetail on top for a guidescope, it's like 10degrees askew and won't sit flat. ARGHH. All three pairs of the top mounting holes are off by 1/2" or so from each other, you'd think they could have at least used a straightedge, or an eyeball. Even though it's out of warranty I tried calling Meade support for advice or at least sympathy, but was rebuffed and told "You can just take it anywhere else to have someone fix it, we can't help you since it's out of production." It's just drilling holes, you don't need a precision jig or special equipment, sheesh. So frustrating they can't even own up to such a major flaw in their assembly. The ACF optics seem ok to me (I upgraded to a Peterson smooth focuser), so faced with having to go through the hassle of selling it at a major loss, I think I'm gonna try to drill and tap some new 8-32 holes myself. I have a few ideas to get the holes orthogonal to the OTA optical axis, if my geometry courses served me well. I will try to tape off the front half of the inside tube and be VERY judicious about removing and dust and shavings, I know this is a serious risk though. Has anyone else tried this?
Last point, I had spotty gotos occasionally but chalked this up to the mount, but I realized that the bottom dovetail mount is also barely aligned to the OTA axis, so that's why my polar alignment always sucks. ARGHHH. On the bottom mount, 3 of the four screws are not even parallel to each other on each cell, and the 4th is rubbing against the radius block mounting hole yet was forced in tightly anyway. When I removed this lower dovetail I saw a hidden extra misdrilled hole completely out of place from the others, so they tried to cover it up. You would think someone would know better, these are not complicated pieces of machinery, and QC totally misses this kind of thing.
