NGC 6781 is a fine planetary nebula and a bright object. The Nebula presents a almost perfect bubble of gas emitted by a single sun like star that died some time ago. The nebula we see is the ejected surface of the star expanding into material left from an earlier stage. At 16.8 magnitude, the central star (a white dwarf) is in the center of the nebula. I started imaging while the object was already into the west, therefore very short exposure time was used to get the complete LRGB set.
The image was taken with a 6 inches f5 Orion Optics UK Newtonian and a QSI WS 583 riding in a SW NEQ6 from Mendoza Argentina. Total exposure time: one and a half hour through LRGB Baader filters. More info at www.baskies.com.ar
