Query: Moduli spaces of SO(8) instantons on smooth ALE spaces as Higgs branches
  of 4d N=2 supersymmetric theories   The worldvolume theory of D3-branes probing four D7-branes and an O7-plane on
$\mathbb{C}^2/\mathbb{Z}_2$ is given by a supersymmetric USp x USp gauge
theory. We demonstrate that, at least for a particular choice of the holonomy
at infinity, we can go to a dual description of the gauge theory, where we can
add a Fayet-Iliopoulos term describing the blowing-up of the orbifold to the
smooth ALE space. This allows us to express the moduli space of SO(8)
instantons on the smooth ALE space as a hyperk\"ahler quotient of a flat space
times the Higgs branch of a class S theory. We also discuss a generalization to
$\mathbb{C}^2/\mathbb{Z}_{2n}$, and speculate how to extend the analysis to
bigger SO groups and to ALE spaces of other types.
