      “The Fighting Dragons of Ara” – RCW 108 in SHO

      Captured by Telescope Live, processed by Cosmin Batica (CBAstro)


      Two colossal dragons of gas and fire clash in the southern constellation Ara — a stellar battlefield where creation and destruction intertwine.

      This is RCW 108, a vast H II region at the edge of the Ara OB1 association, where powerful stellar winds and ultraviolet radiation carve the surrounding molecular clouds into magnificent, flame-like structures.


      Rendered in the SHO palette, this deep narrowband composition reveals the nebula’s elemental anatomy:


      Sulfur-II (SII) blazes in red and orange — the scorching breath of the dragons.


      Hydrogen-alpha (Ha) burns golden through the dense molecular ridges.


      Oxygen-III (OIII) paints ethereal cyan tones — the cooling plasma of ancient stellar outflows.


      With over 10 hours of integration, this image captures both the raw violence and delicate beauty of star formation — a moment frozen between chaos and creation, where the cosmos itself seems to breathe fire.
