Rasdow solar telescope
About this image
The Rasdow is used to watch the Sun continuously (when the weather permits!) to provide a monitor of solar conditions. Astronomers using the principal solar telescopes on Kitt Peak, such as the McMath-Pierce, do not otherwise have a way to check on outside conditions from inside their enclosed control rooms. The picture from the Rasdow is piped around to various locations and can often alert the astronomer to the presence of light cloud or other problems which could compromise the quality of the data. The KPNO 2.1-meter telescope is visible in the background.
