NGC 7822
See my 2019 effort HERE
The above image only covers part of the full nebula and unfortunately is lacking much SII & OIII data that I really wanted to add (but was thwarted by high humidity & strong moonlight). It may get added later. I hope you still find the image interesting. The below info was taken from a previous NASA APOD image of the area.
Cosmic pillars of gas and dust seem to crowd into NGC 7822. At the edge of a giant molecular cloud toward the northern constellation Cepheus, the glowing star forming region lies about 3,000 light-years away. Within the nebula, bright edges and dark shapes are highlighted in this colorful skyscape. The image includes data from narrowband filters, mapping emission from atomic oxygen, hydrogen, and sulfur into blue, green, and red hues. The atomic emission is powered by energetic radiation from the hot stars, whose powerful winds and radiation also sculpt and erode the denser pillar shapes. Stars could still be forming inside the pillars by gravitational collapse, but as the pillars are eroded away, any forming stars will ultimately be cutoff from their reservoir of star stuff.
