NGC 2626

From 04/24/2022 to 05/03/2022, I spent some time at the astrofarm Tivoli in Namibia. During that stay, I captured several deep images of the southern sky using the equipment of the observatory Drebach South. One of the objects I imaged was the fascinating nebular complex NGC 2626, located in the constellation Vela.

NGC 2626 is a particularly interesting object because it combines several different types of nebulae within a single field. The region contains bright reflection nebulosity, reddish emission nebulae, and extensive dark absorption clouds that obscure the background Milky Way. This interplay between illuminated and obscuring interstellar matter creates a highly structured and visually dramatic appearance.

At the center of the nebula lies the variable star R Monocerotis—actually correction: for NGC 2626 the illuminating source is the young stellar object ESO-Hα 18—whose radiation illuminates the surrounding dust clouds. The region is associated with ongoing star formation, where dense molecular clouds collapse to form new stellar systems. Deep images reveal fine dust filaments, compact reflection regions, and glowing hydrogen structures shaped by stellar radiation and winds.

Because this nebula lies deep in the rich southern Milky Way, the surrounding field is densely populated with stars and faint background nebulosity. Under the pristine Namibian skies, extremely subtle structures became visible, including delicate transitions between dark dust lanes and faint reflection features that are difficult to capture from northern locations.

Scientifically, regions like NGC 2626 are important laboratories for studying the interaction between young stars and the interstellar medium. The coexistence of emission, reflection, and absorption nebulae within the same cloud complex provides insight into different physical processes occurring simultaneously during stellar evolution and star formation.

Data calibration and registration and the final processing was done with PixInsight. The result was as follows:
