The Carter Observatory stands at the top of the Botanic Gardens in Wellington, New Zealand. It re-opened in March 2010 following a NZ$5 million refurbishment, with a new exhibition and digital planetarium celebrating the culture, heritage and science of the Southern Skies.
The Carter Observatory houses two main telescopes within its main building and a third telescope nearby. The Thomas Cooke telescope, a historic 9¾-inch Cooke Refractor named after Thomas Cooke, serves primarily for public observing sessions. The Ruth Crisp telescope, described below, arrived as a donation in the 1960s. Not far from its main building, the Carter Observatory operates the Thomas King Observatory, used until recently for public viewing of the sun.
The Ruth Crisp Telescope
The Ruth Crisp Telescope, a research-grade 41-cm (16-inch) Cassegrain reflector made by Boller and Chivens of the USA 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.
A grant from Pub Charity allowed improvements to the installation in December 2005: the Observatory had the dome motorised and the primary and secondary mirrors re-aluminised. Efforts have commenced to start a research programme based around the facility, possibly involving deep-sky imaging, microlensing capability and photometry.
The Thomas King Observatory
The Carter Observatory also operates the nearby Thomas King Observatory. Astronomers have maintained its 12.5 cm (5-inch) telescope (made in 1882 by Grubb in Dublin) in good condition throughout its nearly 125-year history.Last refurbished in May 2001, the Thomas King telescope served until recently for public viewing of the sun, with a hydrogen-alpha filter attached. The filter has since transferred to a telescope mounted to the side of the Thomas Cooke refractor in the main observatory building.
