As some of the largest stars in diameter, red supergiants (RSGs) are ideal targets
for interferometric imaging. In the past few years, studies have begun to shed light
on the evolution of the surfaces and atmospheres of these stars, which deviate from
centrosymmetry. In particular, RSGs have large granulation features which vary on
timescales on the order of hundreds of days. In order to study these features and
their evolution, we have undertaken a long-term imaging survey of RSGs using MIRC
on the CHARA Array. We are seeking the highest resolution images of RSGs possible
with CHARA, looking for variations of features less than half the size of the stellar
surface. Here we present a method for determining the best method for reconstruction
in order to minimize the impact of artifacts.
