Solar Prominence of 12-21-02

This image shows the approximate size of the Earth compared to the Sun.  The Earth is about 8,000 miles in diameter and the Sun is 865,000 miles in diameter.

This CCD image was taken with a 5" f/6 AP refractor  SBIG ST2000 camera and a Coronado 90 H-a filter.  The disk of the sun was blocked out for contrast.  The image was processed using MaxIm DL and Photoshop (false color added).
