1.0-meter fully automatic T100 telescope was installed in 2009 at the south peak of the Bakirlitepe. The first light was taken in October, 2009. This telescope has the largest format CCD camera dedicated to wide-field imaging and high precision photometric observations.
T100 is currently operated remotely from TUG Administration Building in Antalya. This telescope is mainly used in multi-band photometric observations of exosolar planets, stars and asteroids as well as follow-up observations of GAIA or GRB alerts.
