Hi there :)
I thought I might post this web link which I found very interesting about collimating newtonians and what a well collimated scope should look like down the focuser.

After trying to line things up over the last few days as described in most books etc, the light cone still was not centered till I came across this site which showed me what it should look like. After a few hours I finally got my mirrors lined up!!! You definately need that offset!!! and it throws of the symetrical view down the focuser..
Cheers Gary :thumbsup:
