Here is a quick sketch of Minkowski 1-92 (Footprint Nebula) in Cygnus. This, along with nearby Campbell's Hydrogen Star are two nebulas that were difficult in the past. Mainly due to inexperience. Both are small and located crowded star fields . I've made a study of being able to locate them from memory. Observed them with small and large apertures. Both are easily visible in a 6" and image.jpeg stellar at low power.
