Hi All, I've been having issues on and off now for a few years with bad collimation on my 8" newt. Well first off my main problem was the laser collimation unit was NOT accurate at all. In fact it was making things worse, anyway I've discovered a fast
instrument free method that works, well for me anyway in 4 simple steps.
1/ Remove eyepiece & wind the focuser all the way in.
2/ Cover the Primary mirror with clean white paper.
3/ look through focuser tube & note if you can see the secondary mirror is concentric. If not adjust secondary until all is equally positioned though the focus tube while looking in.
4/ Remove the primary mirror white paper & again look down the focus tube. You should note the position of your eye's pupil in the reflection, now just adjust the Primary mirror only until your pupil is
dead center of the reflection.
That's it, My newt has never been so sharp & the view so even. I hope this works for you as well as it did for me.
