i don't really trust my laser collimator tool for a few reasons,
1) i am not sure how the image is affected by weight changes when i ad barlows etc
2) my laser collimator may be slightly out of collimation
3) i am trying to be as perfect as possible for get great planetary images

my thought was that i could load up my imaging train and then point to an object like Saturn or the moon, go out of focus a bit and manipulate the primary mirror until the shadow of the secondary is directly in the middle of the disk of light. would this work or am i missing something that is making me sound stupid?
