The colourful but obscure area in the Cepheus Milky Way that contains the Lion Nebula (at bottom), a region emitting both red Hydrogen-alpha light and cyan Oxygen III light. It is a nebula that only recently became popular as an astrophoto target, perhaps because of its new nickname and from the use of narrowband filters to bring it out. It is not in the popular Messier, NGC or IC catalogues but is officially labeled as Sharpless 2-132. Meanwhile at top, the brightest nebula is the even more obscure Sharpless 2-135, alongside a very faint band of nebulosity that might not have a catalogue number — I couldn't find one!
The nebulosity at top is a deeper red than the Lion Nebula, as the top area of sky contains more dark dust absorbing and reddening the nebulosity and also decreasing the star density and yellowing the sky compared to the richer, brighter and bluer region at bottom to the south around the Lion.
There is a very small (like a fuzzy red star) planetary nebula just right of centre called the Little Ring Nebula, or M2-51, from the Minkowski catalogue. Another tiny planetary in the extreme lower left corner is Abell 79. The field of view here is 5° by 3.3°, with north up.
The star at upper left is the famous variable and double star Delta Cephei. The yellow star at right is Zeta Cephei.
This is a stack of 48 sub-frames taken over two nights, all with the SharpStar 94mm EDPH refractor at f/4.4 and the Canon Ra camera:
- A stack of 16 x 8-minute exposures with a "clear" filter, an Astronomik UV/IR cut filter at ISO 800
- A stack of 16 x 12-minute exposures through an IDAS NB1 dual-narrowband filter at ISO 1600
- A stack of 16 x 16-minute exposures through an IDAS NBX dual ultra-narrowband filter at ISO 1600. This set was shot on night #2 as there was not enough time to shoot it on the same night at the other sets.
The clear filter set contributes the sky background and natural star colours. The NB1 filter set contributes most of the red H-alpha component, while the "extreme" NBX filter contributes mostly the cyan OIII emission which the Lion Nebula has in abundance, somewhat unusually for an emission nebula.
All stacked, aligned, merged and masked in Photoshop 2021. Luminosity masks with Lumenzia helped bring out the faint nebulosity.
Taken from home. Autoguided with the MGEN3 autoguider applying a dithering move between each exposure average out thermal noise when aligning and stacking. No LENR or dark frames were employed on this frosty night! At one point late on night 2 the little guidescope frosted over as the guide star was lost. Hair dryer to the rescue!

These cosmic clouds have blossomed 1,300 light-years away, in the fertile starfields of the constellation Cepheus. Called the Iris Nebula, NGC 7023 is not the only nebula to evoke the imagery of flowers, though. Still, this deep telescopic image shows off the Iris Nebula's range of colors and symmetries, embedded in surrounding fields of interstellar dust. Within the Iris itself, dusty nebular material surrounds a hot, young star. The dominant color of the brighter reflection nebula is blue, characteristic of dust grains reflecting starlight. Central filaments of the reflection nebula glow with a faint reddish photoluminesence as some dust grains effectively convert the star's invisible ultraviolet radiation to visible red light. Infrared observations indicate that this nebula contains complex carbon molecules known as PAHs. The pretty blue petals of the Iris Nebula span about six light-years. The colorful field-of-view stretches almost five Full Moons across the sky.

NGC 7023
The “iris nebula” is a bright reflection nebula in the constellation Cepheus (the King). Best seen in the Fall and Winter months, northern hemisphere. In astronomy, reflection nebulae are clouds of interstellar dust which might reflect the light of a nearby star or stars. Dust in space reflects blue light more efficiently than red which is why almost all reflection nebulae are blue. A similar phenomenon is the reason for blue skies! The designation NGC 7023 refers to the central star cluster. The Iris is “only” 1300 light years distant and about 6 light years across.

Here is my latest photo of the Wizard Nebula, taken using a camera and a small telescope from my backyard. This emission nebula lies in Cepheus, and if you have a clear view of this constellation, you can capture it this month.
To create this image, I used narrowband filters with my astronomy camera to separate the different wavelengths of light emitted by this object. It sounds a lot more complicated than it is, but it's a great way to do astrophotography from a light-polluted backyard!

The Iris Nebula is a reflection nebula located in the constellation Cepheus near the star Polaris in our northern sky. It is approximately 6 light years across and about 1300 light years from earth.
The nebula's blue color is caused by the scattering of light from the central star , HD 200775, by the dust grains within the nebula.
This image is the result of 865 ten second images taken with the ZWO SeeStar telescope stacked and processed in PixInsight.
The overhead northern summer Milky Way through the Summer Triangle area, from Cepheus at top and down into Scutum at bottom. At centre are the Summer Triangle stars of Deneb, Vega and Altair, in Cygnus, Lyra and Aquila respectively. The bright Cygnus Starcloud is at centre; the Scutum Starcloud is at bottom. The dark Cygnus Rift of dust in the Milky Way runs from Deneb above centre, to Serpens at bottom and beyond to the south. The red North America Nebula is at top beside Deneb. Above it is the dark patch known as LeGentil 3 or the Funnel Cloud Nebula.

LDN1251 is an elongated molecular cloud on the eastern edge of the Cepheus molecular cloud complex, an extended region containing giant molecular clouds and very young and bright blue stars associations. It is one of the closest star-forming regions to us and it appears considerably obscured, especially as regards the OB associations, by extensive dark nebulae placed along our line of sight. The comet shape of LDN1251 suggests that it is in interaction with the large super-bubble caused by the explosion of a supernova. Its distance from us has been determined in various ways and different emission lines have been detected, such as the 13CO, the SiO, NH3, HCN and others. Two small galaxies are visible in the field, PGC69472 e PGC166755, just near the edge of the cloud body, along with numerous Herbig-Haro objects, visible as small patches of nebulosity associated with newly born stars.

Sh2-132 is a faint nebula in the border of Cepheus constellation approx. 11,400 light years away from our planet.
This is an emission nebula, where massive stars are responsible for ionizing the gas in this region. In particular, two Wolf-Rayet stars - WR152 & 153 (HD 211564 & 211853) are identified.
These stars are at least 20 times more massive than our Sun and they tend to be eruptive and possess extremely high solar winds.
One of the Wolf-Rayet star, are easily visible bubble in the radio wave band, and it is identified as Shell B, probably originating from the stellar wind of the two massive stars.

Cygnus or the Northern Cross is setting amid the pine trees at Athabasca Falls in Jasper National Park, on a late October night. Cepheus is above and the bright star Vega is low and just above the trees. Deneb is at centre, as is the dark nebula Lynds 3, the Funnel Cloud Nebula. Light cloud adds the natural star glows but also discolours the sky near the horizon.
This is a stack of 7 exposures for the trees, mean combined to smooth noise, and one exposure for the sky, all untracked, and all 25 seconds at f/2 with the 20mm Sigma lens and Nikon D750 at ISO 6400.
The Cave Nebula (Sh2-155) is a diffuse nebula in the constellation Cepheus, within a larger nebula complex containing emission, reflection, and dark nebulosity. It is an ionized H II region with ongoing star formation activity, at an estimated distance of 2400 light-years.
It has been suggested that radiation from the hot O-type star HD 217086 (second from top, middle) is compressing the region, triggering the formation of a new generation of stars.
The bright red part of the Cave is light emission from excited Hydrogen gas, with some reflection of starlight also present. The region is partly obscured by dark foreground clouds of dust and gas.
The name "Cave Nebula" was coined for this object by Patrick Moore, presumably derived from photographic images showing a curved arc of emission nebulosity corresponding to a cave mouth.

The cliffs are a stack of 11 15 s exposures with the settings shown in the EXIF info. The illumination on them was mostly from the waning gibbous moon (back over my right shoulder as I was taking this), but there was uneven illumination from passing vehicles. Stacking the images smoothed that out. The sky is a stack of 9 images. Preprocessing and stacking was done in PixInsight, along with intial processing. Beyond that, most adjustments took place in GIMP.

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.

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.

I wasn’t happy with previous version, so i reedited this widefield.
2 picture mosaic (43*60sec, 50mm, f3.5, ISO3200). I love this area of Milky Way, full of light/dark nebulas, stars and starclusters.

Sharpless 2-132 is a very faint nebula in Cepheus, interesting because of the uneven distribution of gasses. The blue areas are rich in Oxygen-III, while the red areas are rich in Hydrogen-alpha.
Taken with a Stellarvue SVS130 and STL-4020M CCD camera. Hydrogen-alpha was used as red, and Oxygen-III was used as blue and green. Processed in MaximDL and Photoshop.
Rail Operations Group Class 37, 37884 'Cepheus' accelerates up to line speed heading away from Abbotswood Junction working the 5D76 07:02 Worcester Middle Siding to Lydney Up Goods Loop with with barrier vehicles plus 37510 'Orion' dead on the rear. The consist heading to the Dean Forest Railway for their Diesel Gala.
How many more years this view will be available is questionable as a planning application has been submitted to Build 1200 homes, a school and a Solar Farm on this field and the field behind out of site.

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.

My latest image from the backyard is the dynamic-looking 'Lion Nebula' in the constellation Cepheus. (I love the colors in this one)
This image includes exactly 7 hours of total exposure time (84 x 300s) using the little RedCat 51 telescope with a color camera and light pollution filter attached.
The Optolong L-eXtreme filter has officially become my most used filter of all time - and it consistently provides me with useful data from my Bortle 6 backyard.
Dual-narrowband filters have really made astrophotography from the city a lot more obtainable.
