Description

You can see NGC6910 and the star Sadr here.

The weather currently over Germany is terrible. Nevertheless, I have a longer cloud gap on July 7th. used to take a closer look in this region and to practice with the Mgen II. In the end this beautiful picture was taken.

At a distance of 3700 light-years, the open cluster NGC 6910 is located in an extented nebula region in the constellation Cygnus and not far off the galactic plane. This explains the yellow color of the stars in contrast to the blue foreground stars in the vicinity of NGC 6910. The most obvious example is star SAO 49563: the spectral type is B1.5Ia - this star should shine bluish. But due to interstellar extinction and reddening from interstellar dust, the star appears in yellowish color.
