Description

Unfortunately the transparency was not good this night. Again and again clouds passed through. Technical problems I had also. The telescope pushed against the tripod as it turned around. This changed the collimation. So sorry that the stars are not round.
Maybe you like it anyway.

Object description (wikipedia.org):

The Dumbbell Nebula (also known as Apple Core Nebula, Messier 27, M 27, or NGC 6853) is a planetary nebula in the constellation Vulpecula, at a distance of about 1,360 light-years.
This object was the first planetary nebula to be discovered; by Charles Messier in 1764. At its brightness of visual magnitude 7.5 and its diameter of about 8 arcminutes, it is easily visible in binoculars and a popular observing target in amateur telescopes.
