Strategies for Prime Focus Instrumentation in Off-Axis Gregorian Systems

摘要

A new generation of off-axis telescopes has been proposed to address a number of high dynamic range problems in astrophysics. These systems present unusual problems and opportunities for the instrument designer. We will discuss some of the issues that must be resolved when placing instrumentation at the prune focus. The heat stop and occulter systems for the SOLAR-C Off-axis Coronagraph will be used to illustrate strategies for solar telescope applications.
