Summary

Description
English: This image was obtained with the wide-field view of the Mosaic camera on the WIYN 0.9m-meter telescope at Kitt Peak National Observatory. Sh2-284 is a giant HII region. Inside of it is an open star cluster, whose light is energizing the hydrogen gas in the nebula. Stellar winds from the star cluster are clearing out the center of the nebula, giving it a distinctive hollow spherical shape. The image was generated with observations in the Hydrogen alpha (red) and Oxygen [OIII] (blue) filters. In this image, North is left, East is down.
