The Colour Splash of Cygnus Loop

“The layers and structures of the Cygnus Loop are so sophisticated,” U.S. photographer Min Xie said of the supernova remnant visible in this “highly commended” image in the 2021 “Stars and Nebula” category.

“This is an image that every astronomer and astrophotographer wants to see at least once in their lifetime: the entire, pure Cygnus supernova remnant, cleared from every disturbing element,” said László Francsics, competition judge. “As a result, this calm, emblematic bubble structure emerges from the dark, with uncountable details. This astro-image is a unique photograph.”

Equipment used: Takahashi FSQ-106EDX III telescope with f/3 0.6x reducer, Chroma filters, Astro-Physics Mach1GTO CP3 mount, ZWO ASI1600MM-Cool camera, Ha-SII-OIII composite, 168 hours total exposure
