(*) - Addendum
It has come to our attention that we are not the first to image the pulsar wind nebula around PSR B1951+32
It was first imaged by Nicolas Outters in 2016: http://outters.fr/wp/?p=3876
We present our sincere apologies for that mistake.


New Horizon project
The project New Horizon lead by @Tim Schaeffer and editor @William Ostling aims tor explore the celestial sphere in a systematic and methodical way.
Part of this project, I have shot this amazing region in Cygnus.

Wanderers
I would like to start with this very inspiring quote from Carl Sagan, that is the text for the brillant short science-fiction movie Wanderers by Erik Wernquist: https://www.youtube.com/watch?v=YH3c1QZzRK4

For all its material advantages, the sedentary life has left us edgy, unfulfilled. Even after 400 generations in villages and cities, we haven’t forgotten. The open road still softly calls, like a nearly forgotten song of childhood. We invest far-off places with a certain romance. This appeal, I suspect, has been meticulously crafted by natural selection as an essential element in our survival. Long summers, mild winters, rich harvests, plentiful game—none of them lasts forever. It is beyond our powers to predict the future. Catastrophic events have a way of sneaking up on us, of catching us unaware. Your own life, or your band’s, or even your species’ might be owed to a restless few—drawn, by a craving they can hardly articulate or understand, to undiscovered lands and new worlds.

Herman Melville, in Moby Dick, spoke for wanderers in all epochs and meridians: “I am tormented with an everlasting itch for things remote. I love to sail forbidden seas…”

Maybe it’s a little early. Maybe the time is not quite yet. But those other worlds— promising untold opportunities—beckon.

Silently, they orbit the Sun, waiting.
―Carl Sagan




Introduction
We are proposing three edits for this work: SHO edited by Will, SHOO edited by Will and an SHO edit by myself.
Note: you may click on all images in the description to access its revision in full quality, or external reference.


In this mesmerizing cosmic canvas, we are treated to a celestial spectacle that showcases the breathtaking diversity of our universe. The image is a tapestry of colors, shapes, and intricate structures, a testament to the intricate dance of stars and the beauty they leave in their wake.

Surrounding these celestial jewels is a vast and detail-rich nebula that serves as the backdrop to this cosmic masterpiece. Its countless tendrils and filaments weave an intricate web of gas and dust, revealing the dynamic and ever-evolving nature of our universe. Hidden star-forming regions, dark molecular clouds, and the birthplaces of new stars add depth to this breathtaking vista.





PWN PSR B1951+32
At the core of this intricate scene lies PSR B1951+32, a pulsar surrounded by a pulsar wind nebula (PWN). This PWN, visible in a stunning array of colors, takes its place as the centerpiece of this image, capturing the imagination and serving as the first-ever color image of its kind in visible light. It pulsates with life, its energetic emissions shaping the surrounding space and illuminating the cosmic tapestry.

PSR B1951+32: The pulsar at the center of this composition, surrounded by its pulsar wind nebula, emits powerful beams of radiation as it rapidly rotates. These emissions influence the surrounding space and provide a unique backdrop to the cosmic scene.

The radio pulsar PSR B1951+32 was discovered by Kulkarni et al. (1988) and Clifton et al. in the core of the galactic SNR CTB80, as suggested by Strom (1987) [2], [4].

CTB 80 is a Galactic SNR (supernova remnant) with a hybrid radio morphology, consisting of a flat spectrum central nebula, referred to as the plateau region, and three extended arms, each about 30′ long, pointing to the east, north and southwest, that intersect at the center. On the western end of the central emission plateau nebula, there is a compact radio source named “the core” (size 45") which hosts the pulsar PSR B1951+32 [2], [3], [4].

Pulsar wind nebula, Will's and my SHO edits:




OU-7
At the very heart of this celestial portrait stands OU-7, taking center stage as the captivating planetary nebula. OU-7 dominates the scene with its intricate and mesmerizing form, resembling an otherworldly hourglass in vivid hues. Its radiant blues and greens offer a stunning contrast to the surrounding space.
This celestial gem is the focal point of the image, captivating viewers with its intricate details and vibrant colors. Its unique structure is a result of complex interactions between the central star and the material it expelled in its final stages.

OU-7, Will's SHO edit:




OU-8
Just above OU-7, the cosmic stage welcomes OU-8, a new candidate in this celestial ballet. OU-8 enriches the composition with its own unique features, appearing resplendent in green in the SHO (Sulfur, Hydrogen, and Oxygen) color scheme. Its addition to the cosmic tableau adds a fabulous and mysterious dimension to the composition, further showcasing the diversity of planetary nebulae in the universe.

PN G067.9+02.4
Adjacent to OU-7 and OU-8, PN G067.9+02.4 graces the composition with its own luminous presence. This planetary nebula exhibits a unique elliptical silhouette, adding to the cosmic diversity on display. Its colors, likely a blend of blues and greens, hint at the presence of oxygen-rich regions within the nebula, showcasing the chemical complexity of the universe.

PN G068+02.1
Further to the left, PN G068+02.1 captivates the observer with its vivid colors and form. Its shape, sculpted by the interplay of stellar winds and the surrounding medium, adds depth and variety to the cosmic scene.

Pa 137
Pa 137 discovered by amateur astronomer Dana Patchik and listed as a true planetary nebula on French planetary nebulae news and catalogs , captures the curiosity of astronomers and stargazers alike. This celestial object is a probable planetary nebula, as classified in the DSH list (Détails des spectres d'Huynh, Stark, et Heber). Observations of Pa 137 were conducted on September 13, 2018, at the Kermerrien Observatory in Porspoder, France. The dedicated observer for this observation was @Pascal Le Dû . While further study and analysis may be required to confirm its planetary nebula status, Pa 137 serves as a reminder of the ongoing quest to understand the intricacies of the cosmos. As astronomers continue to investigate and unravel the mysteries of objects like Pa 137, they contribute to our expanding knowledge of the universe and the beauty it holds.
