There is the possibility that your scope still isn't collimated for a
variety of reasons, not the least of which is a minor error in the tilt of
your secondary mirror. My advice to you to not worry about focuser tilt
(inless it's wildly off), to put the laser collimator in a drawer
somewhere, get out a plane ol' Cheshire eyepiece, and follow Nils Olof
Carlin's clear and concise collimation instructions as shown here:
