False-color contrast-enhanced image of the Ring Nebula M57 in the light of double ionized oxygen, the forbidden [O III] line at 501 nm. In this image, colors represent intensity levels, in order to visualize the faint and bright structures simultaneously. To stretch the visual dynamic range, a strong false color look-up table was taken together with a double logarithmic intensity scaling.

The image was taken by T. Credner, T. Bonev, and K. Jockers of the University of Bonn with a 576 x 387 CCD, an IF501 [O III] filter, through the 2-meter f/2.8 telescope of the Pik Terskol, Caucasus Observatory, exposed for 5 minutes on April 13, 1997, 1:15 UT.
