The Ruth Crisp Telescope, a research-grade 41-cm (16-inch) Cassegrain reflector made by Boller and Chivens came to the observatory in the 1960s thanks to a donation by the New Zealand writer and philanthropist Ruth Crisp. Once used for research at the Carter Observatory’s outstation at Black Birch, in the South Island of New Zealand, it later moved to the main premises in Wellington.
