+The XRT controls filter imaging using two sequentially positioned filter wheels, as shown in the diagram below.  Each wheel houses a variety of filters. By rotating these wheels, scientists can select different filters to study the sun in multiple wavelengths, thereby enhancing the resolution and quality of solar images.
