F.L. Whipple Observatory image of M57, taken by Nelson Caldwell. Notice the very blue color of the hot central star.

This true-colour image of the Ring Nebula M57 was taken in 1999 by Daniel Folha and Simon Tulloch of the Isaac Newton Group (ING) using the 1-meter Jacobus Kapteyn Telescope (JKT) and the SITe2 detector.

This is an image of the Ring Nebula Taken at the Riverside Telescope Makers Conference for the CCD Shootoff. It is a 2 minute image, self guided with an ST-7.

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.

2MASS infrared image of planetary nebula Messier 57, the Ring Nebula. This is a false-color image, mapping different IR wavelength bands to different colors. The red color in the outer regions of the nebulae arises from emission by atomic and molecular hydrogen in the 2 micron wavelength band. Notice that the central star is very faint in this image, due to its intrinsically blue color and high temperature. Field size is 9.5' x 7.9'.
