Abstract

An uv three-channel photographic photometer designed for broadband photometry of uv-rich stars is described. The optical design consists of two instruments. First, an off-axis telescope, imaging a 7° × 9° field of view, simultaneously records two channels centered at 1878 Å and 2970 Å (636-Å FWHM). The second is a Schmidt-Cassegrainian telescope imaging a 5° × 7° field of view at λ_eff = 2574 Å (358-Å FWHM). Thirty-four star fields have been observed including the Large and Small Magellanic clouds, the nucleus of the Andromeda galaxy, and galactic nebulae in the Carina, Orion, and Taurus regions. More than 3000 stars have been recorded at 2574 Å with a limiting visual magnitude approaching 12. A short discussion concerning the behavior of the emulsions is given.
