Abstract : A model 75-000, high-speed, plane grating spectrograph was modified inexpensively to improve the definition, resolution, and stigmatic images. The cassette has also been modified to accept 4- by 5-inch plates or films, or a Polaroid 4- by 5-inch film holder. With these modifications, step filters or rotating sectors can be used with the spectrograph and the 4- by 5-inch plates fit the microphotometers and comparators without cutting. Four applications of the modified system are described. The instrument can be quickly and easily restored to its original configuration for use at full aperture. (Author)
