luminosity spectrograph. With its slit, LISA is specially designed for
faint or extended objects.
It is an educational tool for students to quickly record spectra of stars and nebulae and focus on actual project rather than long observing hours.
It is also a scientific
tool to study faint objects (novae, variable stars, comets, asteroids,
nebulae, galaxies, quasars...), to monitor group of stars, to chemically
analyse planets in visible or near infra-red light, etc...
