Astronomical images, courtesy of Bob Goodrich, Mike Bolte, and the ESI team.
- Stephan's Quintet,
a small compact group of galaxies.
- The Ring Nebula, M57,
a planetary nebula in Lyra.
- NGC 7662,
a planetary nebula in Andromeda.
- V645 Cyg, The Duck Nebula,
a young star in Cygnus. The outline of the ``duck'' is better seen in
longer exposures, and in recent years the duck has lost its beak!
Images taken in 1985
show a distinct narrow feature which has since disappeared.
The feature was likely a beam of light escaping through a small
opening in a shroud of dust clouds. Movement of the clouds since 1985 has
closed the hole, and turned off the illumination in this part of the nebula.
- NGC 891,
an edge-on spiral galaxy in Andromeda. This image was taken with the
new, full-field Ellis R filter. Scattered moonlight affects the upper
half of the image.
