Spiky stars and spooky shapes abound in this deep cosmic skyscape. Its well-composed field of view covers about a Full Moon on the sky toward the constellation Pegasus. Of course the brighter stars show diffraction spikes, the commonly seen effect of internal supports in reflecting telescopes, and lie well within our own Milky Way galaxy. The faint but pervasive clouds of interstellar dust ride above the galactic plane and dimly reflect the Milky Way’s combined starlight. Known as high latitude cirrus or integrated flux nebulae they are associated with molecular clouds. In this case, the diffuse cloud cataloged as MBM 54, less than a thousand light-years distant, fills the scene. The galaxy seemingly tangled in the dust is the striking spiral galaxy NGC 7497 some 60 million light-years away. Seen almost edge-on near the center of the field, NGC 7497’s own spiral arms and dust lanes echo the colors of the Milky Way’s stars and dust.

在這深邃的宇宙星空中，尖銳的星星和詭異的形狀佈滿整片視野，涵蓋了約一個滿月的面積，朝向星座飛馬座。眾所周知，亮星出現的衍射尖峰是因為反射望遠鏡內部支架的常見效應，而這些星星恰好位於我們自己的銀河系內部。滲透在星際塵埃雲中的難以捉摸的灰蒙蒙雲彩，悠然橫越銀河平面，微弱地反射著銀河系的星光。這些被稱為高緯度雲或綜合通量星雲的雲，與分子雲相關。在這個例子中，該稀薄的雲被編號為 MBM 54，距離我們不到一千光年，充滿了整個畫面。在場景的中央，我們可以看到一個引人注目的螺旋星系 NGC 7497，距離我們約六千萬光年。從幾乎側面的角度觀察，NGC 7497 的螺旋臂和塵埃帶呼應著銀河系中星星和塵埃的顏色。
