Open cluster NGC6939 is just a lunar diameter away from the fireworks galaxy NGC6946. While the latter is young and active, NGC6939 is one of the oldest objects of its kind, dominated by yellow stars while blue ones are missing. astrobin.com/p9idl9 #astrophotography 🔭📷

Lower: The "Fireworks Galaxy" NGC 6946, 19 million light years away and nicknamed after its many supernovae. Upper: Open cluster NGC 6939, 5900 light years away. #astrophotography #seestar #ngc6946 #ngc6939
A swirl of stars and a smattering of stars.

Next - three #OpenClusters with very different stories #NGC6791 is 8 billion years old, #NGC6939 rocks in at 1 billion while #M29 is the baby at 10 million years old. It's interesting science - most clusters are done and dusted (dissolve) after 500 million... yet some survive MUCH longer 🔭 2/5

My latest capture: Here's NGC6946 and its open cluster NGC6939 at 4 o'clock. "Located between the constellations of Cygnus and Cepheus, the galaxy is ~ 20M LY away... so, admittedly, less spectacular than M31, but still, how beautiful! #Astronomy #Astrophotography #DeepSky

A wide-field astrophotograph showing two main celestial objects. In the lower right is NGC 6939, a tight grouping of bluish stars forming an open star cluster. In the upper left is NGC 6946, a bright face-on spiral galaxy with dusty arms, tinged in subtle red and blue hues. Faint interstellar dust clouds stretch across the image, giving it a textured appearance. The entire scene is filled with tiny stars from our Milky Way in the background.
