This image here is from a newt in which the collimation shifted as the altitude changed. It is worse on the right instead of the left, but generally looks very much like your shot if not worse.

What you should try is setting up your laser and adjust it as best you can, then hang the camera off the focuser with a loop of string and watch what the weight of the camera does to collimation.

Also have a read of Moon's write up on these scopes here.
