📸 Ou4: The Giant Squid Nebula
This elusive nebula glows in blue from oxygen atoms and may lie 2,300 light-years away inside Sh2-129. Powered by a triple star system, its outflows span 50+ light-years. A true deep sky giant.

Djaffar nous partage cette magnifique #astrophotographie
Nous y voyons, en "bleu" #ou4 la #nébuleuse planétaire du Calamar Géant ainsi que la nébuleuse de la Chauve-souris #sh2-129 en "rouge"
Ce n’est vraiment pas évident comme objet. Le Calamar Géant est très discret sur les brutes, raison pour laquelle il faut des temps de pose très longs, 15 minutes par photos. Il y a en tout 58h de signal étalées de mai à août 2024

#Ou4 is the most extensive planetary #Nebula to date. Known as the Giant Squid Nebula, it is a bipolar nebula that stretches a dizzying length of 50 light years. This is more than an apparent degree in the sky, or twice the diameter of the Full Moon.

It is a very faint planetary nebula located in the constellation Cepheus.

¡#HolaCiencia! ¿Un #calamar? ¡No! La nebulosa del calamar #Ou4 es un objeto muy tenue de unos 50 años luz de longitud que se extiende a lo largo de un grado en el cielo de Cefeo • #FotoCiencia Aleix Roig 🦑

#SkyWatch #Astrophotography The red in this image is part of the large jydrogen emission nebula called the #FlyingBat aka #SH2-129 which is 2300light years from Earth in the #Cepheus constellation. I was also targeting the #Squid nebula aka #OU4 which is the faint blueish-green area in the image. This nebula is so faint that it was only discovered in 2011. This image is only 2.5 hours of exposure so I'm confident I can get more detail in the future. #StillLearning
