The INAF Campo Imperatore Observatory in Abruzzo (Italy) as an Earth Observation Facility for the Study of Venus Night Airglows (VNAs)

The National Institute for Astrophysics (INAF) Campo Imperatore Observatory is located in the Gran Sasso mountains in Abruzzo, Italy, at an altitude of 2150 m above the sea level. The atmospheric transparency, along with the climatic conditions - especially in winter - have always made it a suitable site for observations in the near infrared (1 - 2 micron).

The Campo Imperatore Observatory is equipped with the AZT-24 reflecting telescope, Ritchey-Chrétien configuration, with an aperture of 1.1 m. The new motorization system – currently in the commissioning phase - will allow great pointing and tracking accuracy (<0.1 arcsec), as well as an uncommonly fast-tracking speed (the mechanics is designed to reach 3 degrees/second). With this facility we are starting the ADvanced VENus’ Night Airglows Near-infrared Telescope (ADVENANT) project, which aims to observe and study Venus’ nightside airglows (VNAs).
