Next up from the processing stack - #Caldwell27 or the #CrescentNebula (although for me it's a "brain"!) I am constantly amazed that we can, relatively quickly, catch such objects from a back garden - amateur astronomy really has changed over the last 5 years 🤯 #EAA #astrophotography #astronomy 🔭

NGC 6888 Crescent Nebula - telescope processed image. NGC 6888 is an emission nebula in Cygnus. Its crescent shape is formed by the fast stellar wind of a massive Wolf-Rayet star (WR 136) colliding with its slower, previously ejected material.

Good Saturday morning. Starting this morning with some observations done with the s50 last night. I think the planner feature on the s50 is awesome. Here is #NGC6888 #CrescentNebula. #seestar #S50 #space #astronomy #amateur

This time I put in over 34 hours into the Crescent Nebula. I was quite disappointed in my previous attempt which was seriously lacking Oiii data. I and devoted more than twice the time and even had enough clear skies to capture RGB stars! ⭐️

An image of the Crescent Nebula.  Mainly gases of red and yellow making up a nebula that I think looks more like a shell, than a crescent.  The nebula is surrounded by many stars as well as other red gases.

The Crescent Nebula Astrophotography often leads us to stunning cosmic vistas hidden in plain sight among the stars. My latest adventure brought me face to face with the mesmerizing Crescent Nebula (NGC 6888), a jewel nestled within the rich tapestry of the Cygnus constellation. Located approximately 5,000 light-years from Earth in the constellation Cygnus, the Crescent Nebula is a brilliant example of a Wolf-Rayet nebula. Its distinctive shape - reminiscent of a cosmic bubble or crescent - is not the work of quiet celestial processes, but rather the direct result of ferocious stellar winds. At the heart of the nebula lies WR 136, a massive star nearing the end of its life. Thousands of years ago, WR 136 shed much of its outer layers during its red giant phase. Now, as a Wolf-Rayet star, WR 136 unleashes intense, fast-moving stellar winds, which slam into the slower-moving material previously ejected. This collision produces intricate shock waves and energizes the surrounding gas, causing it to glow in the vibrant reds and blues captured in my image. What you see here is a region where cosmic creation and destruction intertwine - a stellar relic that embodies both the violent and beautiful forces shaping our universe. ## The Imaging Experience Capturing NGC 6888 required careful planning, precise tracking, and several hours of exposure to unveil its delicate shells of ionized hydrogen and oxygen. The result is a tapestry of glowing filaments, intricate gas structures, and a hint of the larger Cygnus molecular clouds in the background. The nebula’s colors, largely the result of hydrogen-alpha and oxygen emissions, highlight the chemical complexity forged by WR 136’s tumultuous history. ## Why NGC 6888 Inspires Wonder The Crescent Nebula stands as a testament to stellar evolution - a brief, brilliant phase before WR 136 will eventually explode as a supernova, further enriching its surroundings with heavier elements. Each capture, each photon collected from NGC 6888, allows us to witness the legacy of cosmic cycles that have shaped galaxies for billions of years. Whether you’re an avid astronomer or simply captivated by the night sky, NGC 6888 reminds us of the universe’s dynamic beauty and the ever-changing tapestry above us.

 I was shocked when I first looked at the data—a reaction perfectly suited to this target. The Crescent Nebula's striking structure is shaped by expanding shock waves. This began when the Wolf-Rayet star (WR 136) at the center of the emission nebula, while still in its red giant phase, ejected stellar wind that is now colliding with a much more energetic wind from WR 136. These winds create shock waves that travel both inward and outward, leading to strong emissions from hydrogen and oxygen atoms.

For the first time, I used narrowband filters with my mono astro camera to extract the famous H-alpha emission line from the Balmer series (deep red at 656nm) and the OIII emission (between blue and green at 500nm) - both very common in many deep sky objects. It's standard practice to map the hydrogen emission to the red channel in a traditional RGB image, and the oxygen emission to both the green and blue channels. To complete the image, I added an hour of broadband data to preserve the natural star colors, which can be lost with narrowband filters.

Swipe for a starless version, a more detailed view of NGC 6888, the two mono channels, and a short video blinking through the two channels.
