TUG060 Telescope

As Türkiye's largest investment in fundamental science, forming the space sciences ecosystem,we are an advanced research infrastructure founded in partnership between Atatürk University and TÜBİTAK.

Photometry projects of long-period variable stars are conducted with this telescope.

Focal Plane Instruments

The telescope has a 12-position filter wheel at its focal plane. On the new Andor camera, the readout rate is set to 1 MHz, the preamplifier gain to x4 and the mode to High Sensitivity. The 'TIME-OBS' time in the CCD header is the UT time at which the exposure began.
