More narrowband: Dumbbell Nebula, Cocoon Nebula and Sadr Region

Less than 1 minute Minutes
The last few days of July 2022 I had several consecutive clear nights, and I imaged multiple targets, including two emission nebulae (Cocoon Nebula and the Sadr Region) and one of my favorite planetary nebulae (the Dumbbell Nebula – M27).
 
I made some tweaks to enhance my imaging routine:
  • I added the Celestron PWI (CPWI) Telescope Control Software for the initial alignment of my equatorial mount and to connect the mount to the imaging software (NINA) and the guiding software (PHD2);
  • I installed NoiseXTerminator, a plugin for PixInsight that, thanks to AI technology, removes background noise from images without affecting stars or DSO. Considering that the total integration time for each image was less than 1 hour, I was quite impressed by the final results.

I was able to capture the outermost layers of this beautiful planetary nebula.
M27 (2022-07-28)
The Cocoon Nebula (IC 5146, or also Caldwell 19, Sh 2-125, Barnard 168) is an emission / reflection nebula in constellation Cygnus. It’s a stellar nursery where hundreds stars are forming. Its distance is 3,260 light years.

Cocoon Nebula (IC1546)
The Sadr Region (IC 1318 or Gamma Cygni Nebula) is a diffuse emission nebula surrounding the star Gamma Cygni (Sadr), located in the heart of Cygnus’s cross and with a magnitude of 2.2. Sadr is approximately 1,800 light years distant, while the nebula is much further away, at 4,900 light years.
