Full-disk solar Dopplergrams observed with a one-megapixel CCD camera and a sodium magneto-optical filterThe paper presents here the first two full-disk solar Dopplergrams obtained with the new 1024 x 1024-pixel CCD camera which has recently been installed at the 60-Foot Tower Telescope of the Mt. Wilson Observatory. These Dopplergrams have a spatial resolution of 2.2 arcseconds and were obtained in a total of one minute of time. The Dopplergrams were obtained with a magnetooptical filter which was designed to obtain images in the two Na D lines. The filter and the camera were operated together as part of the development of a solar oscillations imager experiment which is currently being designed at JPL for the Joint NASA/ESA Solar and Heliospheric Observatory mission. Two different images obtained by subtracting two pairs of the Dopplergrams from the initial time series are also included.
