Location: Team Ager network: seven located in the Sierra del Montsec, together with the Albatàrrec Observatory. (Lleida, Spain)

Data Acquisition Method: Personal Telescope Setup

Description and Details: Eight members. Eight observatories. Ten telescopes. 509 hours of integration.

This image of the faint Vulcan Nebula is the result of a collaborative project developed by Team Ager, an eight-member group united by a shared passion for deep-sky astrophotography and dark skies.
Over more than 22 months, we combined data from eight observatories forming part of the Team Ager network: seven located in the Sierra del Montsec, together with the Albatàrrec Observatory, which contributed a significant part of the project's data.

A total of 10 refracting telescopes, ranging from 54 to 140 mm in aperture, contributed to the project using different cameras, focal lengths, and filter configurations. The final result contains 509 hours of actual integration, corresponding to approximately 3,244 long-exposure frames.

The integration time was distributed across 28.4 hours of luminance, 33.1 hours of RGB, 211.95 hours of Hα, and 235.55 hours of OIII. The exceptionally large amount of narrowband integration allowed us to reach particularly deep into the faintest structures of the nebula, revealing a complex network of interstellar gas and filaments.
The final processing was carried out in PixInsight, integrating all the data from the different instruments and observatories into a single image. The reddish structures are dominated by hydrogen-alpha emission, while the blue and turquoise structures reveal the contribution of ionized oxygen.

But the depth achieved extends beyond the nebula itself. M81 (Bode's Galaxy) and M82 (the Cigar Galaxy) are clearly visible in the field, accompanied by numerous much fainter background galaxies.

More than an individual image, Vulcan is the result of 22 months of shared work, eight observatories, ten telescopes, and 509 hours of integration, demonstrating how far amateur astrophotography can reach when knowledge, equipment, and collective effort are brought together in a single project.
