I would be interested to hear a comparison of the XX12 vs. XT10 line. There is a significant increase in weight, cost, and complexity from one to the other...is there a significant increase in capabilities to justify the additional issues created?

As far as the gotos are concerned - problem solved. I started thinking that the problem was really always having to slew left or right to find the object, so before I turn the scope on I manually line it up and put Polaris in the crosshairs in the reticle, then set the tube back to the zero pointer, then turn it on and do an alignment. So its working. Also, doing it this way, simply turning on tracking without even bothering with alignment also works very well.
That being said though, my only real gripe with the firmware remains the lack of a spiral search function. The spiral search function would be immensely helpful.
As far as comparing the XT10 to an XX12, I don't know that you can really make a case of comparing apples to oranges on these two scopes. I think the XX12G is easy to transport, set up and tear down. The XT10 is easy to transport, set up and tear down, probably easier. But that comes at a cost - the length of the tube in transport. If you notice I have a lot of stuff that I take to dark sky sites for 3-4 nights at a time. All the stuff in the picture, plus the stuff for camping, although I pack light. But it all has to fit in a Toyota Matrix. Enter the XX series - because it breaks down into smaller pieces, it fits for me. That was my single biggest deciding factor in my purchase. It was all about my transport needs. If you only transport a single scope, or have the luxury of only observing from the backyard, the tube dobs are a great value and make sense. In essence, I paid about a 600.00 premium for my particular needs in transport - and still think I got a great deal considering the cost of a larger car. Whether to get the 10 or 12 in terms of optimum aperture vs. cost, that debate will rage forever in the reflector forum.

How well does the light shroud fit? Tight enough to keep creepy-crawlies out?

I've loved my XT10i for about 5 years now...
Now start modding it...
Get yourself some flocking... Then upgrade the focuser...
Then if you really want to seriously be blown away...
Get in touch with Carl Zambuto and do a mirror upgrade... Trust me it is worth it... I'm never selling my 250mm Zambuto, unless I could get a 300mm or 350, or ...
You get the idea...
My factory mirror was a good one... But upgrading to ZOC, priceless, especially via Ethos or Pentax XW's...
The beauty of all these Orion's is they are worth investing in!
Nice review... I may just consider getting the XT10 go to baby brother and swap me mirror... Yeah, I am a goto addict...

My next decision for me will be whether to get the 14in xxg, or the celestron 14in cgem. Cost will tell me the orion.

The gotos on my XX12g are spot on every time and centered in a 12mm eyepiece.The trick is to make sure the base is perfectly leveled .I built an adjustable X cross brace with levelers to make the base perfectly level.Once that has been done the Gotos in mine are spot on.
When I just push the scope around and stop on an object the tracking remains solid for an hour plus again in the 12mm eyepiece.
The biggest problem was the plastic hand control holder bracket,I built a new one out of aluminum and that problem is solved.
THe focuser was replaced with a Moonlite and a filter slide.
The secondary screws removed with Bob's Knobs for hands on easy adjustments .
My primary mirror was tested at 1/8 wave and gives killer views.
Many people have looked thru this scope at multiple star parties and the comments are always Wow or something on those lines.
The deep sky views are very solid and defined and bright.
It's a heck of a dob and at $2,400.00 with all the bags and what have you Orion has built a nice package here.
My other scope is a Takahashi TOA 150B so I am use to very sharp views and this XX12g is very good indeed.
I am all to way to the bank.
