Astronomical observations with an SEC vidicon system.

Description of the design and operation of an SEC vidicon camera system, and review of some of the astronomical observations performed with it. Following a discussion of the main system and instrumentation features and a delineation of present and future software tasks, the preliminary series of observations obtained in conjunction with the 36-inch telescope at Kitt Peak National Observatory is briefly surveyed. These observations include (1) exposures on the Orion Nebula through various narrow-band interference filters, and (2) exposures on the galaxy Messier 82 in white light and with medium band filters.
