These are two little-photographed nebulae in the Southern Hemisphere, located in the constellation of Vela and apparently linked to each other. GUM14, the largest, is an emission nebula excited by a class O blue supergiant and prospectively adjacent to a complex of reflection nebulae the most important of which is NGC2626. GUM15 is another emission nebula which, together with GUM14, belongs to the Vela Molecular Ridge: a mega molecular complex full of young and hot stars, which, thanks to their radiation, becomes visible to our telescopes
For this image, more than a dozen of highly motivated astrophotographers combined their skills to obtain a unique amazing image. To get to this level of details, the group rent over several nights a Riccardi-Honders RH 200 scope located in the Southern Hemisphere, i.e., Rio Hurtado, Chile. The colors palette of the image is obtained by combining different wavelengths together, namely Ha, Oiii, and LRGB filters.
