Emission Nebula Sh2-140
This image was obtained with the wide-field view of the Mosaic camera on the Mayall 4-meter telescope at Kitt Peak National Observatory. Sh2-140 is an HII emission nebula on the southwest edge of the Lynds 1204 darn nebula. It is also on the edge the Cephus Ring, a ring of molecular gas and dust. Invisible in this image, there are about fifty young stars deeply embedded in the dark gas in the lower-left corner of the image. The image was generated with observations in the B (blue), I (orange) and Hydrogen-Alpha (red) filters. In this image, North is left, East is down.
