collimation questions

Can someone reccommend a good site that details each and every step of
collimation from adjusting spider vanes, secondary tilt, sec up/down etc?
Especially with some decent diagrams that show what you should see. I
just cant get this new scope collimated, i can get everything "but one"
lined up. The primary looks centered in the secondary and its circular,
In the center of that image of the primary, when looking through the pinhole
EP, there are 2 small dark circles, one slightly smaller than the other,
then there is also the little donut marker on the primary. My question is,
do these two small circles need to be centered over each other and then the
primary adjusted to move the little donut over the center of that?
I tried to diagram what i see: http://24.18.62.225:8080
The black area is the secondary. The White area is the reflection of the
primary mirror, the little gray dot is the center mark on the primary, What
are the blue and green circles? do they need to be concentric with each
other?
Thanks
Eric
