NGC6369 is a small planetary nebula located near the southeastern edge of the constellation Ophiuchus, about 2 degrees northeast of the θOph. It has a beautiful red, donut-like shape with an apparent diameter of 38 arcseconds, and the central 16th-magnitude white dwarf is clearly visible. Faint nebulosity can also be seen extending beyond the donut shape. This nebula is nicknamed the "Little Ghost Nebula". The distance to NGC6369 is uncertain, estimated to be between 2000 and 5000 light-years, and its actual diameter is about 1 light-year.
