This add-on adds a realistic, fully 3D model of the planetary nebula Abell 6. Abell 6 is a faint planetary nebula, and is often photographed alongside the visually nearby planetary nebula Heckathorn-Fesen-Gull 1 (HFG 1), which is not included here. The nebula is poorly studied, so the actual 3D structure is not known; my model is a best guess that appears correct from Earth's viewpoint while appearing realistic from other directions.
