The surrounding faint nebula complex as a whole, on the other hand, is difficult to make out. The objects are located in the constellation of Vulpecula. The nebula consists of the open star cluster NGC6823, the emission nebula NGC6820 itself and the surrounding nebula structures with the distinctive ‘snorkel’ and the ‘nebula spiral’. The complex is a typical Ha region, i.e. a star-forming region. The gas cloud emits the light of the still young surrounding stars. Almost 50 massive agglomerations of dense gas have been discovered within the gas clouds.
