I must say I'm surprised at the lack of quality of your XT6's focuser (image shift). I went through three products before purchasing my XT6, and returned them all with the focuser being extemely poor in all three. One was a Celestron refractor, and two were from Meade, both reflecters. All three of them had an EXTREMEM amount of image shift when I focused in or out, and the Meade focuser was obvious after thought cheap plastic junk. The instant I first focused with my XT6 is was so overwhelmingly obvious it was better than my previous purchases I knew (or assumed) the rest of the scope would prove as nice, which it did. Granted I'm an extreme amateur, I still can spot obvious differences in workmanship. I'm willing to bet if you called Orion they would be happy to exchange your scope.

>Optics provide good resolution; but my other six-incher, the Celestron CR150HD refractor, shows slightly more detail (albeit with a purple halo around bright objects). The XT6 does a good job on double stars, but getting any significant detail out of the larger globular clusters with the XT6 is a bit dicey under "typical" city observing conditions. In a semi-dark location, clusters such as M13 and M22 yield a few resolved stars with typical conditions. I suspect it would take exceptional conditions to dig any stars out medium clusters such as M92 and M15. The XT6 splits the double-double with Orion's 15mm Ultrscopic combined with their Ultrascopic barlow. And in the moments of clear viewing, it can be seen that the split is quite clean. A star test looks good. I think the optics on this scope will make it a good planetary and double star scope, but I can't verify its planetary abilities at this time since the only view I've had of Saturn has been low in the sky on a so-so night.
>I do have some complaints about the mechanical qualities of the scope.
>The mount is rather stiff, probably because the spring tension supplies a little too much tension. When adjusting altitude, there is a tendency of the bearings to initially resist movement then suddenly break loose causing you to go past your target (I think this is called "stiction".). I haven't gotten around to it yet, but I intend to move the teflon base pads a bit closer in to the center to make azimuth movements a little easier; either that or do the milk carton thing.
