Major components in the optical are airglow (much in isolated atomic and molecular emission lines) and scattered starlight from Solar System dust (zodiaal light) and interstellar dust.
In addition an Optical Laboratory with a variety of instrumentation used for the passive study of terrestrial airglow is located at the Observatory.
