Abstract

The planets telescope structure is a hybrid off-axis design that uses a carbon truss to support the secondary mirror and an aluminum base to support the primary mirror and provide an interface to the declination rotation axis. This paper describes the development of the optical support structure of the telescope, which required an integrated model to predict closed-loop optical metrics in the presence of wind loading. The integrated model combined a finite element model, the optical prescription, a control model and measured wind loading.
