SH2-248 in modified SHO Integration: 5125 min (240x300, 138x600 HaO3; 47x600, 415x300 S2O3). Broadband stars (30x300 UVIR filter) SH2-248, aka IC443, aka “the Jellyfish Nebula,” is a supernova remnant (SNR) located roughly 5,000 light-years from Earth. The yellow “Jellyfish” portion of the nebula is approximately 70 light-years in diameter. This image is shot using a modified “Hubble Palette,” aka “SHO Palette”, with red representing ionized sulfur, green ionized hydrogen, and blue ionized oxygen. The strong yellow colors of the jellyfish portion of the nebula show that sulfur and hydroge
