  We study N = 2 supersymmetric gauge theories with gauge group SU(2) coupled
to fundamental flavours, covering all asymptotically free and conformal cases.
We re-derive, from the conformal field theory perspective, the differential
equations satisfied by omega deformed instanton partition functions. We confirm
their validity at leading order in one of the deformation parameters via a
saddle-point analysis of the partition function. In the semi-classical limit we
show that these differential equations take a form amenable to exact WKB
analysis. We compute the monodromy group associated to the differential
equations in terms of deformed and Borel resummed Seiberg-Witten data. For each
case, we study pairs of Stokes graphs that are related by flips and pops, and
show that the monodromy groups allow one to confirm the Stokes automorphisms
that arise as the phase of the deformation parameter is varied. Finally, we
relate the Borel resummed monodromies with the traditional Seiberg-Witten
variables in the semi-classical limit.
