The NASA Solar Terrestrial Relations Observatory (STEREO) mission will place two spacecraft into solar orbits with sufficient separation to provide remote sensing instruments with a stereoscopic view of the heliosphere extending from the lower solar corona to beyond one astronomical unit. Analysis of the stereographs returned from the two spacecraft will allow solar physicists to infer the three-dimensional structure of small and large components of the corona. The Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) suite of remote sensing instruments includes a Heliospheric Imager (HI) to view the heliosphere in the interval from 12 to 215 solar radii. The HI will obtain the first stereographic images of coronal mass ejections in interplanetary space. Of particular interest is the subset of coronal mass ejections that propagate through the heliosphere and ultimately impact the earth. This paper presents the design concept for this new wide field coronagraph.
