On this page I collect my observations of the planetary nebula NGC 6818, called Little Gem Nebula, in the constellation Sagittarius.
The planetary nebula NGC 6818, called Little Gem Nebula, in the constellation Sagittarius is according to Stoyan very small and bright.
A little more than 40' away from the planetary nebula NGC 6818, the galaxy NGC 6822 (Barnard's Galaxy) is located. In Vespera (and eVscope 2), both could therefore be observed in the same field of view. The planetary nebula is, however, much, much closer (6,000 LY) to Earth than the galaxy (1.6 million LY).
