Explanation: Stars are forming in Lynds Dark Nebula (LDN) 1251. About 1,000 light-years away and drifting above the plane of our Milky Way galaxy, the dusty molecular cloud is part of a complex of dark nebulae mapped toward the Cepheus flare region. Across the spectrum, astronomical explorations of the obscuring interstellar clouds reveal energetic shocks and outflows associated with newborn stars, including the telltale reddish glow from scattered Herbig-Haro objects seen in this sharp image. Distant background galaxies also lurk on the scene, buried behind the dusty expanse. This alluring view imaged with a backyard telescope and broadband filters spans about two full moons on the sky, or 17 light-years at the estimated distance of LDN 1251.

说明:恒星正形成于林茨暗星云(LDN)1251之内。在1,000光年远处的这团尘埃分子云,是漂浮在我们银河系盘面之上,位在仙王座爆发区方向的成群暗星云之一部分。在各个电磁波段针对这个黝黑星际尘埃所进行的探索,发现了许多和新诞生恒星相关的高能激波和外泛流,包括散布在这张清晰影像中的特征性泛红赫比格-哈罗天体。在视野中,还有藏在广袤尘埃云后方,隐约可见的遥远背景星系。这幅透过宽度段滤镜拍摄的后院望远镜影像,大约涵盖了2个满月天空,以LDN 1251估计距离来换算,其宽度约莫有17光年。(Lynds Dark Nebula 林茨暗星云)
