Hi Ben,
By an ealier post I think you have a 10" newt.
If you have a newt. and if the spot is very close to the center of the primary mirror then it should not matter. The secondary mirror blocks any light that would fall in the center of the primary.
Collimation can be very tricky. I have had problems getting my 8" newt. colimated and have read lots of articles. From what I know you should be able to see all mirror clips through the focuser. If not I adjust the angle of the secondary mirror until you do. Hope this helps.

Dave
