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 yea

Recent Progress on the Columbus Project and the Mirror Laboratory Programhas been re-optimized to allow rapid changes between foci, while still maintaining high rigidity. Room has been made to translate secondary and tertiary spiders out of the light path to the center. A bill allowing construction of the telescope on Mt. Graham, Arizona, has been passed by Congress and

The U.S. National 8 M Telescope Project. Optical configurations, primary mirror systems, and the telescope mounting are discussed. A new optical testing method is outlined. The system imaging goal is 0.25 FWHM. Construction could begin in the early 1990’s.

Still a further order of magnitude reduction is possible if the telescope is specialized for on-axis spectroscopy, giving up especially the luxuries of wide field, multiple focal positions, and access to all the sky at will.
