M57 is another famous and often photographed object. It is also known as the Ring Nebula. ... Of course, they have nothing to do with planets but rather represent late stages in the evolution of low mass stars in which a double shell source (Hydrogen and Helium Burning) around a non-fusing Carbon core is driving the outer layes of the star away, thus revealing a hotter star (the central star of the Planetary nebula). ...

... Hence, this could lead to sources being spuriously treated as being the same one, although it is currently believed that the offsets will change very little from one exposure to another within an observation. If this is confirmed, then omsrclistcomb may eventually correct the positions when the master source-list table has been produced- otherwise omatt will attempt to correct the positions for each source-list, although this clearly won't be possible when the image only contains a few stars. ...
