Chromospheres: 51 μ² Boötis A

51 Mu-2 Boötis A (Chromosphere #178) is a piece from the third and final collection in Spectra's Dawn Trilogy. The Chromospheres collection comprises 707 pieces; each an artistic expression of a star from our night's sky. The rendering of each Chromosphere required the simulation of over half a trillion light rays, and each incorporates actual astronomical data from the star that it represents.
