Stellar Shot of the Week

SVX130T - Dark Shark

October 13, 2026 - Mark Savan

Mark Savan captured this spectacular shot of the Dark Shark Nebula in Cepheus with his SVX130T. This Dark Nebula is located approximately 650 light-years away from Earth and spans about 15 light-years across. The interstellar gas cloud in this object is mainly composed of hydrogen and helium, with traces of other elements like carbon, oxygen and nitrogen. The entire complex associated with this nebula is one of several regions known for star formation in the “Cepheus Flare.”
