The Westerlund telescope was installed in its 6 m diameter dome on the fifth floor of Ångström Laboratory in October, 2003. It is a 90 cm classical Cassegrain reflector with two Nasmyth foci for semi-permanent mounting of different types of instrumentation. The main purpose of the telescope is undergraduate education and introduction to practical astronomical observation methods. The telescope is also used for professional research projects.
