I have 16" Lightbridge. With all the mass produced telescopes paricularly the truss tube type collimation is the difference between great performance and mediochre performance. There are quite a few other threads on collimation. The basic tests that are usually the only ones done by most people are only part of the job. Real collimation is much more tedious in getting the wave front in phase so that the full use is made of the mirror. Only a star test diffraction pattern will show you this is OK.
