This shows an apparent problem with Y axis orientation between two models.
Attempting to align the Y axis "hale_telescope" with "hale_yoke"

<p>
The upper (rightmost) model of the telescope uses a secondary axis with 
positive y specified to be aligned with the positive Y axis of the yoke.
But it points in the opposite direction.

The lower (leftmost) model of the telescope uses a secondary axis with 
negative y specified to be aligned with the positive Y axis of the yoke.
That points in the same direction.
