A Large Reflective Schmidt Telescope for the Antarctic Plateau

We present a design concept for a 16 metre, wide-field, fixed-axis, all-reflective, segmented f/4 Schmidt telescope to take advantage of the unique possibilities of Antarctica for both optical and near infrared astronomy. The design allows observation of all RA/dec’s accessible from Antarctica, with...

Description
Summary:We present a design concept for a 16 metre, wide-field, fixed-axis, all-reflective, segmented f/4 Schmidt telescope to take advantage of the unique possibilities of Antarctica for both optical and near infrared astronomy. The design allows observation of all RA/dec’s accessible from Antarctica, with tracking times of several hours. Prime and Cassegrain foci are provided, giving plate scales 300-3000µm/", over fields of view 1.5'-0.5º. Diffraction limited, natural guide-star AOcorrected Kdark images are possible over arc-minute sized fields, over 70 % of the sky. The sensitivity, resolution, field of view and cost all compare favourably with current or proposed space or ground-based telescopes.
