  We show that pairs $(X,Y)$ of 1-spherical objects in $A_\infty$-categories,
such that the morphism space ${\rm Hom}(X,Y)$ is concentrated in degree 0, can
be described by certain noncommutative orders over (possibly stacky) curves. In
fact, we establish a more precise correspondence at the level of isomorphism of
moduli spaces which we show to be affine schemes of finite type over ${\Bbb
Z}$.
