I have heard that the Cheshire eyepiece is a more accurate way of collimating a telescope.
Comments / advice on this subject would be most welcome.

The other alternative is to pop the laser in a barlow and look for the doughnut reflected back up the drawtube. I believe this skirts the problems of having your laser out of collimation. I've been using this method and it seems to work fine - very easy. I had to fashion a cap from an old eyepiece cover to fit over the drawtube inside the OTA (bit like the BLUG).
