For the 3rd Team image, here's the open cluster NGC 6866, located in the constellation Cygnus.
NGC 6866 is an open cluster in the constellation Cygnus. It was discovered by the German astronomer Caroline Herschel in 1783.
The cluster features around a hundred young stars, including a large number of beautiful bluish stars.
According to Robert Trumpler's classification of open clusters, it contains around 100 stars, with a medium concentration (II) and magnitude distribution.
It lies in the foreground of the Cygnus-X complex, a giant cloud of gas and dust around 5000 light-years away and some 700 light-years long, which we highlighted with a long series of Ha exposures.
In the end, the contrast of colors between the red of the emitting gas and the intense blue of the stars gives a more spectacular aspect to the object... itself rather unimpressive because of its medium density.
Happy holidays to all and see you next year for more images!
