I use a laser collimator to collimate my reflector's primary and secondary mirrors which is easy enough. However if I rotate the laser in the eyepiece holder (say quarter of a turn) the laser dot leaves the centre of the circle on the primary mirror.


I do as a test because obviously the eyepieces I put into the holder won't always be rotated the same way. Therefore my question is whether the misalignment that I observe with my laser (when rotated) will affect the overall collimation? Or should the telescope be collimated in such a way that even when you turn the laser in the eyepiece holder, the red dot doesn't leave the primary mirror's circle?
