庞大的发射星云IC 1396和Sh2-129混合了发光的星际气体和黑暗的尘埃云，在这近12度的广角视野中朝向北方的仙王座。它的中心恒星IC 1396（左）为其提供能量，直径数百光年，距离约3000光年。星云迷人的黑色形状包括一个蜿蜒的黑云，俗称象鼻，在中央下方和右侧。它有几十光年长，拥有恒星形成的原材料，并且已知它隐藏着原恒星。Sh2-129与地球的距离相似，右侧明亮的结状和扫过的后脊状发射物让人想起了它的名字——飞蝙蝠星云。在飞行蝙蝠中，这个皇家宇宙动物园最近发现的新成员是Ou4的微弱蓝色发射物，即巨型乌贼星云。在画面右下边缘附近，天空中暗色的标记被编目为巴纳德150，也被称为暗海马星云。值得注意的提交给APOD：英仙座流星雨2023

Sprawling emission nebulae IC 1396 and Sh2-129 mix glowing interstellar gas and dark dust clouds in this nearly 12 degree wide field of view toward the northern constellation Cepheus the King. Energized by its central star IC 1396 (left), is hundreds of light-years across and some 3,000 light-years distant. The nebula's intriguing dark shapes include a winding dark cloud popularly known as the Elephant's Trunk below and right of center. Tens of light-years long, it holds the raw material for star formation and is known to hide protostars within. Located a similar distance from planet Earth, the bright knots and swept back ridges of emission of Sh2-129 on the right suggest its popular name, the Flying Bat Nebula. Within the Flying Bat, the most recently recognized addition to this royal cosmic zoo is the faint bluish emission from Ou4, the Giant Squid Nebula. Near the lower right edge of the frame, the suggestive dark marking on the sky cataloged as Barnard 150 is also known as the dark Seahorse Nebula.
