#NGC6939
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

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

NGC6939散開星団とNGC6946系外銀河 (16年後の再処理画像) - 雲の上には宇宙(そら)
( このシリーズを初めて訪問された方は シリーズ「1X年後の再処理(PixInsigt)画像」スタートにあたって もご参考に ) 2番目の再処理(PixInsight)の対象に選んだ画像は、 前回記事の画像から5カ月後の9月に撮影したケフェウス座の散開星団と渦巻銀河のコンビです。 ( 「天体アルバム」に保存されていた画像です ) ↓ コンビとは言っても現在のwikipediaのデータでは右下 N...
