2.5@C - An Off-Axis Telescope Concept for Antarctic Astronomy
G. Moretto1, Nicolas Epchtein2, Maud Langlois3, Isabelle Vauglin

The Antarctic plateau offers exceptional atmospheric and environmental conditions for astronomical observations over a wide range of wavelengths and uniquely favorable to infrared astronomy. Exceptional low sky brightness throughout the near- and mid-infrared and a telescope facility complying with the highest possible dynamic range for photometry, angular resolution and the wide-field leads to the possibility of a modest-sized 2m off-axis telescope achieving comparable sensitivity to that of a larger ground-based 8-10m class telescope or a same sized space-based ones.
