This image was obtained with the wide-field view of the Mosaic camera on the Mayall 4-meter telescope at Kitt Peak National Observatory. Sh2-239 is a distinct nebula in which stars have been forming for quite some time. It contains two clusters of highly embedded very young stars as well as many stars that are more evolved. The many outflows are visible as bright red knots and jets, particularly in the cavity at the center-top of the image. The image was generated with observations in the B (blue), V (green), I (orange) and Hydrogen-Alpha (red) filters. In this image, North is left, East is down.
