Question about Optics
When trying to focus on a image, I just cannot see any image at all. I am wondering if I have assembled the scope correctly. I have followed the instructions that were included with it, but no success.

SOURCE: Auto Align??? DS-2114ATS-TC
The alignment stars will be nearby BUT MAY NOT BE in the eyepiece-- you must center the alignment stars using the hand controller-- after you center the second star the GOTOs should be OK.

You must align the finder scope with the main telescope tube--
During the daytime look at something far away in the main scope-- without moving the scope center the cross hairs on the finder scope.

SOURCE: can't focus my meade etx-125.
yup there is a mechanical stop to prevent you from cracking the mirror by retracting or extending it too far.. once you break the pin off it needs to go to the factory for dis-assembly as they have to remove the primary to get to it and realign it my 105 did same thing....word of advise use a cable extender for focus not an electric focuser they fail to tell you that it can over run the built in stops making your scope useless...i may be mistaken but i believe the max turns is 25 or about for end to end focusing adjustment on the 125

Some eyepieces will NOT come to focus because the scope does not have enough back-focus, in the focuser. The only thing you can do is try another eyepiece or another eyepiece brand.
