Lynds’ Dark Nebula 673

This image was obtained with the wide-field view of the Mosaic camera on the Mayall 4-meter telescope at Kitt Peak National Observatory. LDN 673 is part of a giant cloud of dust and gas in the constellation of Aquilla. It is fragmented into many pieces, inside of which are forming stars. Some of these stars are illuminating parts of the nebula, such as in the upper-left and upper-right corners. The image was generated with observations in B (blue), V (cyan), I (orange) and H-alpha (red) filters. In this image, North is left, East is down.
