It was realized already at the start of the project that combining the 8 m telescopes would not be realistic without the prior experience with telescopes of an intermediate size. These telescopes could also be coupled with one or several 8 m telescopes once the interferometric techniques are fully developed. This smaller interferometer is likely to consist of 2 to 4 mobile telescopes of about 2 m diameter. Fig. 6. Demonstration prototype of an inflatable dome. This prototype is being tested at La Silla Observatory.

RADIO ASTRONOMY AND VERY LARGE TELESCOPES· NO RIO KAIFU Nobeyama Radio Observatory, National Astronomical Observatory, Nobeyama, Minamimaki, Japan (Received 30 March, 1989) Abstract. The current achievements of the observational abilities of radio astronomy is briefly reviewed putting emphasis on the imaging capability.

Analysis of an idealized computer model predicts that despite dec enter, net tilts and image motions will all be within acceptable limits. It is expected that the Keck telescope will soon take its place in the forefront of the many instruments which wll expand the limits and contribute to the understanding of the visible universe. 42 S.
