Close-up view of the Fossil Footprint Nebula (NGC 7822) captured at 1624 mm with a Ritchey–Chrétien telescope. The long focal length resolves fine filamentary structure along the ionized gas fronts, revealing sharp emission ridges, dark dust intrusions, and subtle texture within the nebula. The image emphasizes the turbulent interaction between intense radiation from young massive stars and the surrounding molecular cloud, giving the nebula its distinctive, sculpted appearance.
