PicturavisGamma Cygni Nebula
The Sadr Region around the central star Sadr (γ Cygni) in the Cygnus constellation contains the large H II nebula, Gamma Cygni Nebula (IC 1318). This nebula is partly obscured by dust, creating the Butterfly Nebula (IC 1318B) in the lower left of the image, just below Sadr.
Many other objects can be seen, including multiple star clusters and, most notably, the Crescent Nebula (NGC 6888) to the right of the center of the image.
This image was created with 2,984 × 2 s (1 h 39 min 28 s) integration time. Post-processing was done with #Siril, #GraXpert, #StarNet++, and #GIMP.
This time I documented the whole process in my #blog. If you have a camera, this is for you (no guarantees, though; I just fail along until it works for me): https://blog.picturavis.com/astrophotography-without-equipment/
