Can´t Center Slideshow CK

Tried this in user css:
.camera_wrap { margin: auto; }

Did not work in Cassiopeia.  Trying it position top-a.  I can add blank modules on the right and left which sort of centers it but not exactly.  Kind of disappoint that such a wonderful module does not have the correct code to work out of the box! 

Hi
the center of the module in your template is not a feature to manage in the slideshow itself, this shall be managed in the template
please give me the url of your page so that I can check the problem
