The 11-in/24-in vacuum reflectors were built by Boller and Chivens. A coud´┐Ż configuration is used to feed a vacuum spectroheliograph, which is too massive to mount directly onto the telescope. The optical path is evacuated to minimize internal seeing effects. Observations of the sun can be made in nearly monochromatic light at any visible or near-infrared wavelength. The 24-in is used primarily for Zeeman (magnetic field) and Doppler shift (velocity) studies. Currently, a CCD detector is used to record 2D polarized spectra of selected regions.
