Ken, I had a similar prob. with my cardboard Meade. The UWA 14mm was too heavy for it, (distance from tube was large), and as such the focuser,(orig. rack & pinion), compressed the tube slightly, putting it all out of line. A small piece of packing under the lower mounting solved the alignment prob.

Just the facts m'am.
