  We present a procedure to optimize the offset angle (usually also known as
the wobble distance) and the signal integration region for the observations and
analysis of extended sources by Imaging Atmospheric Cherenkov Telescopes
(IACTs) such as MAGIC, HESS, VERITAS or (in the near future), CTA. Our method
takes into account the off-axis instrument performance and the emission profile
of the gamma-ray source. We take as case of study indirect dark matter searches
(where an a priori knowledge on the expected signal morphology can be assumed)
and provide optimal pointing strategies to perform searches of dark matter on a
set of dwarf spheroidal galaxies with current and future IACTs.
