Fast digital spectrophometry of celestial bodies
An original digital slitless spectrophotometer with transparentdiffraction gratings has constructed, adjusted, and tested at theCrimean Astrophysical Observatory. It is mounted on the 0.5-m meniscustelescope, has high sensitivity, and enables spectrophotometricobservations of celestial bodies in the region 370-740 nm with exposureof several minutes and absolute photometric accuracy of several percent.The spectrophotometer is intended for studies of rapid variations in thespectra of stars, asteroids, comet nuclei, bright galactic nuclei, etc.
