NGC 6781 – Aql
Among the celestial treasures, planetary nebulae really stand out. Placed at a few thousands of light years from us, NGC 6781 is a perfect example of that. It is one of the apparently largest objects of its type and it is placed in a very rich star field. It was discovered by William Herschel on 30 July 1788.
