MyCn 18 (Etched Hourglass Nebula)
This add-on adds a realistic, fully 3D model of the planetary nebula MyCn 18. MyCn 18 is a bipolar nebula resembling an hourglass, hence its nickname, the "Etched Hourglass Nebula" or the "Engraved Hourglass Nebula". The overall shape of the nebula is based on density simulations by Vincent Icke.
