Abstract

Site seeing at good locations has r_ο (5000 Å) ≈15 cm, and the 5 percentile seeing is about three times better. There are seeing effects at particular locations, but no known geographic trends. The dominant observatory problem is mirror seeing, and ventilated honeycomb mirrors are the current best solution. The detailed effects of phasing precision are discussed. It is assumed that adaptive optics can control separate 2m sized portions of the entrance pupil. Finally the efficiency of use of a telescope is estimated as a function of the image size produced by misfigure, misfocus, misalignment and local seeing etc.
