You need to collimate the new focuser.
I put my laser into the focuser tube and made a white paper circle the same diameter as the dew shield. The paper circle would have a pin hole dead center if you use a compass. Most good focusers have collimation adjustments. Just adjust it so the laser red dot is dead center of the paper circle and your good to go.
I suspect your lens is in collimation but the new focuser is not.
cheers
