The Radio Telescope for 7.9 Meteres Wavelength at the Mullard Observatory

Abstract
This pencil-beam radio telescope, which uses the principle of aperture synthesis, has a resolution of 0.8° × 0.8° at a wavelength of 7.9 m. A survey of the sky between R.A. 05 h and 17 h , Dec. + 10° to + 50°, has proved the performance of the instrument. The map of this region, which is presented in this paper, shows detail of the spur of radio emission at galactic longitude l ′ = 0°; it also shows some discrete sources, including the Coma cluster.
