Re: [ATM] Binocular telescope co-collimation

Not really all that sure about what you are asking.
The ultimate end when collimating a binocular telescope is to
make the two EPs show the same image in them.  This means that
the individual collimations of the two scopes needs to be not
only done to get the best image but the two scopes need to point
at the same spot when they are collimated.  You can forgo
adjustments for pointing if you are close enough to the right
values when you build the scope as they will be close enough if
the errors are averaged.  Tip and tilt on one scope needs reallyy
only be that one secondary needs to be able to be moved in the X
and Y adez to alighn the pointing of the two scopes to each other
as the primary is aligned to the secondary.
The amount of decollimation between the two scopes is somewhat
determined by the focal lratio of the  two scopes as the edge
errors is what will determine the amount of difference in the
images from the two scopes.
Ultimately, when you get the scope aligned, the two images will
be essentially identical.
