Abstract

The use of a Kron electrographic detector for wide-field, narrow-band imagery of faint emission nebulosity in the near-UV and visual (3100-6000 A) wavelength interval is de-scribed. As an example of the photometric quality of the imagery and of the sensitivity of the instrumentation to diffuse, low-contrast objects, imagery of the Cygnus Loop super-nova remnant in the high excitation line of [Ne V]λ3426 A is presented. In addition, we describe our current program to develop electrographic detectors which use cesium tellu-ride photocathodes for broad-band imagery and spectrography in the middle-UV (1650-3100 A) wavelength range.
