The Lagoon & Trifid Region - M8 & M20
Sitting amongst the rich star fields of the Milky Way in Sagittarius, the Lagoon Nebula (M8) and Trifid Nebula (M20) make one of those pairings that just belong in the same frame.
At around 4,000 light-years away, M8 dominates the lower half of the image as a huge region of glowing gas and active star formation. Above it sits M20, easily recognised by the dark dust lanes that divide its bright core into three distinct lobes. What makes the Trifid particularly interesting is the mix happening within the same object — red emission, blue reflection and dense dark dust all sitting together.
Luke processed this one as an LRGBSHO blend, using the narrowband data to bring out the structure and ionised gas throughout the region while retaining the more natural appearance of the stars through the LRGB data.
