Has anyone used one of these looks like the orion one from bintel but with 2" adapter. I have also seen it on Saxon's website.

Is this only for primary adjustment or can it be used for secondary alignment also.
I am in the market for a collimation tool for by 10" dob. My dob does not have a center spot on it.
Please advise.
I have seen the posts on the cheshiere from Andrews, but it does not look long enough to be a good sight tube. Does Andrew sell a longer version?
Does anyone have expereince with Andrew's laser collimators?
