CfA Colloquium: October 17, 2002

Speaker: Jerry Nelson (UCSC)

Title: Large Scale Astronomical Optics

Abstract: Several groups in the astronomical community are seriously studying the possibility of building 30-100m ground based optical telescopes. In this talk I will give a bit of history of large telescopes and their technical challenges. This will be done along with a few remarks on the challenge of building large things in general. I will present some details of the California Extremely Large Telescope (CELT) design study. CELT is a proposal for the University of California and Caltech to build a 30-m ground based telescope. As time permits I may also discuss some of the scientific opportunities, and the particular challenges and scientific returns from using adaptive optics on a 30-m telescope.
