MapCam/PolyCam Overlay

The first light images of star fields from OCAMS’s MapCam and PolyCam illustrate each camera’s specialized function. MapCam’s medium resolution and wider field-of-view will help map the entire surface of Bennu in color. While PolyCam’s field of view is much smaller, it can see much fainter objects at a higher resolution. PolyCam’s ability to act as a telescopic will help the OSIRIS-REx team spot Bennu while it is still a point of light against a field of stars.
