Views of Giant Emission Nebula IC 1396 in Cepheus | Mayall Telescope
These images were obtained with the wide-field view of the Mosaic camera on the Mayall 4-meter telescope at Kitt Peak National Observatory. IC 1396 is a giant emission nebula that is over 3 degrees in diameter. It is illuminated by a hot, massive O-type star (HD 206267) near its center. The star is not visible in this image—it is off of the top edge. This image is of a portion of IC 1396 in the south-eastern part of the nebula. It shows only about 5% of the entire nebula. The image was generated with observations in the Hydrogen alpha (red) and Sulphur [SII] (blue) filters.
The Nicholas U. Mayall Telescope is a four-meter (158 inches) reflector telescope in Arizona named after the American observational astronomer of the same name. The telescope saw first light on February 27, 1973, and was the second-largest in the world at that time.
