This false colour image is a wide field mosaic of bright nebulae including the NGC 2626 region (bottom left), Gum 15 (small, bright, below centre), Gum 17 (middle right), and the north east part of Gum 12, the Vela supernova remnant (the tendrils at top left). The field of view spans 5.1 x 6.7 Degrees. Gum 15 is approximately the size of the full moon (small, bright, below centre). Discovery of vast complex of Gum nebulae is attributed to the Australian Colin Stanley Gum (1924–1960).

I have also included a thumbnail of an [Hydrogen alpha, OIII, OIII] image with RGB stars, which I think is less impactfull, but you may advise otherwise.
