Structure of the Keck Telescope — An Overview segmented primary mirror, by the very stringent weight and cost limitations, and by observational and operational needs. Analysis of a progressively more detailed computer model predicts that all design objectives will be met, as shown in a summary of performance characteristics. The paper is illustrated with a number of drawings.

Concept and Status of the VLT Projectnge of scientific applications. The most far reaching one is the co-phasing of the four telescopes which will open the way to very high resolution imaging..The funding has been granted in December 1987. The first telescope is scheduled for 1995. The whole array is expected to be completed by the year 2000.
