Celestron nexstar 11" gps scope
Be sure that the Azimuth Axis is Lock, you migth want to try and move the telescope in the Azimuth to make sure it is it is locked. Be carful not to force it. I have seen on some post where the locking part of the Azimuth somtimes breaks. and the Azimuth Axis will just spin freely Locked down or not.

Focusing Issue
The screws should be short enough not to stop the primary's travel, but pull them out and try it again. Good luck! George.

Focus knob turns but nothing moves
The Celestron manual for this scope has nothing to say, but on the underside of the focuser assembly, between the 2 focus knobs, you may see 2 screws.They might be thumbscrews or some other screwhead type. One is the adjustment for the focuser internal clearance, or looseness, and the other is a focus travel lock.If present, try backing both off 1/2 turn from tightness, and then experiment to see which is which. The focus lock will have no effect until tight, when the focuser will cease moving, as is now. The other screw will gradually remove looseness and rattle from the focuser until it just moves smoothly, with no back and forth loose feeling at the knob.If neither of these screws is visible you will have to take it to a binocular and telescope shop, where they should not charge much.
What is the weight of the celestron next star se 8
It is impossible to assess the weight (or more correctly Mass of a star, as weight is a perceived function of Earth's gravity) without knowing the chemical make up of the star. That is why astronomers use the star's measured albedo to qualify and quantify them.
We have a celestron 114AZ telescope. we cannot see anything with it. why?
Most problems will be overcome by reading and absorbing the instruction manual.
Assuming the telescope is in good order, it must first be pointed at a light source using the spotter scope and then aligned using the lowest power eyepiece before fitting the high powered eyepiece...
You also should be in very low light conditions.
