I'm pretty new at collimating Newts but I'll give you my method.
(From reading the instruction book, what I've read on here and a bit of intuition.)
I first look straight down the focus tube and wind the adjustment out until I can no longer see the end of the tube in the mirror reflection. My main mirror has 4 clips holding it in place and if I cant see all of them evenly at the edge of the field of view I adjust the secondary till I can. This secondary adjustment has to be done rarely as once its set it will stay pretty well OK unless the tube or spider gets a hard knock. I then put the laser in and fine adjust the secondary so the dot is on the centre spot of the main mirror. The final stage is adjusting the main mirror so the reflected laser spot on the angled cut out on the side of the laser collimator disappears back down the central hole from whence it came.
I hope this helps, I had a hard time getting it right too, but once you've done it a couple of times its not so bad. I don't use the cheshire, just the laser.
Cheers
Bill
