NGC 7538, near the more famous Bubble Nebula, is located in the constellation Cepheus. It is located about 9,100 light-years from Earth. It is home to the biggest yet discovered protostar which is about 300 times the size of the Solar System. It is located in the Perseus Arm of the Milky Way and is probably part of the Cassiopeia OB2 complex. It is a region of active star formation including several luminous near-IR and far-IR sources. Stars in NGC 7538 are mainly low-mass pre-main-sequence stars.

Encompassing the emission region designated Sharpless 171 is the star forming complex NGC7822 lying at a distance of roughly 3200 light years away in the constellation Cepheus is a spectacular example of a stellar nursery. The emission nebula shines as a result of the ionizing radiation from one of the hottest stars known; BD+66, which has a luminosity 100,000 times that of our sun. Curiously enough, BD+66 is also an eclipsing binary, which means that it is actually two stars in orbiting each other and are aligned in such a way that one star occasionally eclipses the other from our perspective, is a very young star forming region; no more than a few million years old. It will continue birthing new stars for several million more years until the radiation from the new stars blows away the last remnants of hydrogen gas, leaving behind a small cluster of young bright stars.

Stunning emission nebula IC 1396 mixes glowing cosmic gas and dark dust clouds in the high and far off constellation of Cepheus. Energized by the bright central star seen here, this star forming region sprawls across hundreds of light-years, spanning over three degrees on the sky while nearly 3,000 light-years from planet Earth. Among the intriguing dark shapes within IC 1396, the winding Elephant's Trunk nebula lies just below center. Stars could still be forming inside the dark shapes by gravitational collapse. But as the denser clouds are eroded away by powerful stellar winds and radiation, any forming stars will ultimately be cutoff from the reservoir of star stuff. The gorgeous color view is a composition of image data from narrowband filters, mapping emission from the nebula's atomic oxygen, hydrogen, and sulfur into blue, green, and red hues.

First subject after the summer holidays, an emission nebula in the constellation Cepheus about 11,000 light years away.
The ionised gases and dark dust draw delicate shapes with reddish colours due to the hydrogen.
In the clear hours over four nights I managed to obtain a good amount of data to process this beautiful nebula.

Bonjour à tous, aujourd’hui, je vous présente la nébuleuse de l’iris (NGC7023) ainsi que la nébuleuse sombre du requin (LDN1235). Cette photo a représenté pour moi, un véritable défi technique puisqu’avec mon matériel actuel, je ne dispose pas d’un système type GoTo.
—
Il m’a fallu dans un premier temps, réussir à me repérer dans le ciel pour mon cadrage. Bien que les nébuleuses se trouvent dans la constellation de Céphée, avec un 135mm, il y a de quoi frôler la crise de nerf. J’ai donc choisi de cadrer depuis l’étoile d’Alfrik qui se trouve plus ou moins à mi-distance des deux cibles.

Here's an interesting duo located near the border of Cepheus and Cygnus. The open cluster NGC 6939 is actually about 5000 light years away, a part of our own Milky Way galaxy. Beside it, but 22 million light years further away is the galaxy NGC 6946. Since the galaxy lies close to the plane of the Milky Way, it is highly obscured by the interstellar dust and material that lies in the foreground. I also learned that it is often called the Fireworks Galaxy because of the number of supernova observed within it.
The image was taken through a Stellarvue SVS130 through red, green, and blue filters (90 minutes each), and enhanced with Hydrogen-alpha (also 90 minutes). Processed in MaximDL, PixInsight, and Photoshop, and upsampled 2x.
Je vous présente la nébuleuse de la trompe de l’éléphant, plus connu sous le nom de IC1396. Elle se situe dans la constellation de Céphée. Il y a 1h30 de signal, dans le futur, je prévois de faire une mosaïque de cette région absolument magnifique et riche en détail.

This image, shot during May to July 2024, shows a heavily crowded are in constellation Cepheus, with a blend of several nebula types. In the center, pillars of dust create a wormlike structure called LDN 1217, which ends in a bluish reflexion nebula (VdB 152). In the background, more dark nebulas can be seen, in some parts being lit by hot blue giants stars. In this area, it partially blocks the red light coming from the Ha strands farther away, which impairs the sense of perspective.
This is my longest project so far (61h29) and one of the hardest. Why? Not because of technical issues but in striking a balance between all these nebulas in a way that any of them overwhelms the others and thus show the richness of this area.
Have I achieved it? Perhaps yes, to my eye. Or maybe not… But the important is that I am quite happy with it.

Here an image of the Cave Nebula, catalogue reference Sh2-155, an emission nebula in the constellation of Cepheus. It is embedded in a larger region containing emission, reflection and dark nebula. The brightest part of the nebula has an apparent magnitude of 7.7, being situated about 2400 ly from Earth. The somewhat unusual rendition shown here is derived from 6 filters in total: Hydrogen-alpha, sulphur-II and oxygen-III ultra-fast narrowband filters and g´, i´, and z-s´ photometric filters. The g´ filter (400-550nm) captures nicely the reflection nebula, whilst the i´ (700-845nm) and z-s´ (820-920nm) filters transmit infrared light at different wavelengths. The data from these two filters then needs to be colour-mapped to a visible region of the spectrum. The following colour mapping has been applied to create this particular image: g´ mid-blue, O-III cyan, Ha yellow, S-II sunset orange, i´ crimson, z-s´ purple. Stars are from the monochrome S-II integration.

The Wizard Nebula is a strong emission nebula of dust and gas surrounding the open star cluster NGC 7380. The nebula is found in the constellation of Cepheus.
The Wizard Nebula itself has the designation Sh2-142 in the Sharpless Catalog of HII rich regions.
Believed to lie at a distance of around 7,000 light years from earth it is known to be a region of active star formation.
The nebula gets its name from the dark dust areas resembling a medieval sorcerer or wizard (complete with pointy hat!) his hands stretched out. Can you see him?

Drifting through the darkness of Cepheus, the Wolf’s Cave Nebula (LDN 1217) emerges as a spectral cloud of dust and gas, shrouded in cosmic mystery. This faint region, illuminated by scattered starlight, is a quiet yet captivating expanse where interstellar winds shape intricate structures hidden within the void.
Dark nebulae like this are dense clouds of cosmic dust that block and scatter visible light from the stars behind them, creating the illusion of empty space. But within these cold, shadowy regions, the raw materials for future stars and planets gather over millions of years. Some areas reflect nearby starlight, forming striking blue-hued reflection nebulae, while others remain obscured, visible only in infrared wavelengths. These vast molecular clouds are the quiet architects of the universe, slowly shaping the galaxies we see today.

Here is an image of the open star cluster NGC 7380, also known as the Wizard Nebula. NGC 7380 is located in the constellation Cepheus about 7,000 light-years from Earth within the Milky Way Galaxy. The star cluster is embedded in a nebula, which spans some 110 light-years. The stars of NGC 7380 have emerged from this star-forming region in the last 5 million years or so, making it a relatively young cluster.

At the heart of this image lies the Shark Nebula, nestled in the constellation Cepheus, a Northern celestial display that graces the night sky prominently throughout the summer months.
Classified as a dark nebula, the Shark Nebula is characterized by dense interstellar dust clouds, capable of absorbing a substantial portion of the starlight that traverses its depths.
Photographing such nebulae presents a challenge due to their low contrast against the vast cosmic background, distinguishing them from the typically brighter reflection or emission nebulae that either reflect starlight or emit ionized light.
Positioned approximately 650 light-years away, the Shark Nebula showcases distinctive features, with the brighter blue reflection areas situated closer to 1,000 light-years. Enhancing the celestial panorama is the inclusion of galaxy PGC 67671, a diminutive yellowish spiral object positioned behind the "dorsal fin" area in the lower-right section. Notably, this distant galaxy is located approximately 58 million light-years behind the entirety of the Shark Nebula, contributing a captivating depth to the cosmic composition.
This project is a continuous endeavor, with my objective being to gather additional data and enrich the information by incorporating more details, particularly in narrow-band imaging. The forthcoming enhancements will focus on intensifying the visibility of all red faint structures in the current image.
Following the completion of my previous work, which involved a close-up capture of the Shark Nebula, I made the decision to embark on a larger-scale wide-field project. In this image, a myriad of nebulae and faint structures come into view, including 8 dark nebulae cataloged as LDN and 10 bright nebulae cataloged as LBN.
This RGB composition is the result of 8 hours of integration time at f/2.

The Wizard Nebula, NGC7380, is an open cluster and emission nebula in the constellation Cepheus. It lies some 7200 light years away and extends over 100 light years, making it appear as large as the full moon. However, it's quite faint for visual detection and typically requires an OIII filter to see it. The center of the nebula is an active star forming region bringing life to new stars that form the cluster, which has existed some 4 million years - very short on cosmic timescales.
This image uses the HST assignment of filters where Sulfur-II = Red, H-alpha = Green, and Oxygen-III = Blue.

In this photo two nebulae are show, the brighter one, on the right is CED 214, while the area to the left is known as NGC7822. The two structures known as emission nebulae are so closely entangled that is difficult to see where one begins and the other ends and there are many dark nebulae between them. The entire structure which is referred to as Sharpless 171 (SH2-171) is located in the constellation Cepheus on the border between Cepheus/Cassiopeia and is also populated by many young hot stars that cause the entire area to glow. This exposure of over 7.8 hours reveals the details using the HST palette which is accomplished by combining sub frames using three narrowband filters that capture light produced by glowing hydrogen (Ha), oxygen (OIII) and sulfur (SII) present in the nebula. Green is assigned to hydrogen, blue to oxygen and red to the sulfur.
Distance from earth is approximately 3000 light years.

This complex of dust is located some 1300 light-years away in the constellation Cepheus, not too far from the popular Iris Nebula. Since this nebula is not light-emitting (hence the "dark" nebula), very dark skies away from light pollution are needed to display the contrast between the faintest of dust and the background sky. For that reason, I took advantage of some of the darkest skies in the nation to capture this image.
Some interesting bits in this image include the galaxy NGC6951 near the left edge of the image. In comparison to the foreground stars and dust, which is cosmically speaking rather near, NGC6951 lies 75 million light-years from Earth.
Another exciting thing to note is that stars are forming within these dark cloud cores. Most notable is HH215 in the upper-right of the image. If you look closely at the "peak" of the nebula, you can see the bright gas ejection caused by the newborn star.
