  Small telescopes equiped with modern instrumentation are gaining on
importance, especially, in the era of exoplanetary space missions such as TESS,
PLATO and ARIEL. Crucial part of every planet hunting mission is now a
ground-based follow-up of detectd planetary candidates. Mid-sized telescopes
with apertures of 2 to 4-m with an existing instrumentation become more and
more valued due to increasing need for observing time. In this paper, a brief
overview on the follow-up process for exoplanetary space missions will be
given. Requirements for the ground-based follow-up instrumentation will be
discussed. Some of existing 2-m class telescope facilities and their capability
and potential for the follow-up process of exoplanetary candidates will be
presented. A special focus will be put on existing 2-m class telescopes in
central Europe.
