Abstract
The PS1 is a wide-field survey telescope which is a prototype for the Pan-STARRS project. It has a 7 square degree field of view, a 1.85-m primary mirror, a 0.9-m secondary mirror, 6 interference filters with 0.48-m diameters, and three corrector lenses with diameters between 0.6 and 0.4-m. The PS1 camera (GPC1) has 0.26" square pixels in a format that includes 1.44 Giga-pixels. The PS1 camera is located on the summit of Haleakala on the island of Maui which has a median seeing of 0.8-0.9". The PS1 telescope has been under commissioning since September 2007. This article describes the mounting and the supports of the PS1 optics as well as the efforts that have been made towards achieving site-limited image quality in the alignment of the telescope optics. We also show here some of the early imaging from this telescope as a function of time during commissioning.
