在这张望远镜拍摄的南方天空图中，黑暗的标记和明亮的星云是年轻恒星和活跃恒星形成的标志。它们位于仅650光年远的地方，位于局部气泡和变色龙分子云复合体的边界上。在1946年的Cederblad星表中，年轻恒星被确定为尘埃反射星云的区域包括中间偏左上方的c形Ced 110，以及它下方的蓝色Ced 111。变色龙红外星云（Cha IRN）的橙色v形星云也是画面中的一个亮点，它是由一颗新形成的低质量恒星流出的物质雕刻而成的。构图良好的图像跨度为1.5度。根据附近的变色龙1号分子云的估计距离，这大约是17光年。

Dark markings and bright nebulae in this telescopic southern sky view are telltale signs of young stars and active star formation. They lie a mere 650 light-years away, at the boundary of the local bubble and the Chamaeleon molecular cloud complex. Regions with young stars identified as dusty reflection nebulae from the 1946 Cederblad catalog include the C-shaped Ced 110 just above and left of center, and bluish Ced 111 below it. Also a standout in the frame, the orange tinted V-shape of the Chamaeleon Infrared Nebula (Cha IRN) was carved by material streaming from a newly formed low-mass star. The well-composed image spans 1.5 degrees. That's about 17 light-years at the estimated distance of the nearby Chamaeleon I molecular cloud.
