My latest image from the backyard is the 'Cosmic Question Mark Nebula' in the constellation Cepheus.
This target includes a large, bright emission nebula (NGC 7822), with a nebulous 'point' at the bottom (Sharpless 170).
If you're in the northern hemisphere, Cepheus is full of photographic nebulae, including this monster.
I used an ultra-portable telescope setup for this one, a wide-field refractor and a one-shot-color astronomy camera.

Caldwell 9 Diffuse Nebula in the Constellation Cepheus
Sh2-155 (also designated Caldwell 9, Sharpless 155 or S155) is a diffuse nebula in the constellation Cepheus, within a larger nebula complex containing emission, reflection, and dark nebulosity. It is widely known as the Cave Nebula, though that name was applied earlier to Ced 201, a different nebula in Cepheus. Sh2-155 is an ionized H II region with ongoing star formation activity, at an estimated distance of 725 parsecs (2400 light-years) from Earth. (Wikipedia.org)

This time I really pushed my setup to its limits: a wide-field view of the dusty regions in the constellation Cepheus, focusing on three stunning deep-sky subjects: LDN 1251, LDN 1235, and VDB152.
Such a wide field was made possible by the combination of the RedCat51 and ASI6200MM full frame camera, which allowed me to capture all these objects in a single frame, without the need for a mosaic.
The idea came from having just a few days under a good mountain sky , I wanted to bring home as much as I could, and I did. I would have loved to go beyond the 11 hours of OIII, 12 hours of Hα, 6 hours of Luminance, and 6 hours of RGB, but the weather was a relentless adversary this time.
This image is also special for another reason: it’s my last one with the RedCat51. After more than two years together, my “red cat” will soon move to a new owner. It has been my inseparable companion, light yet precise, and has followed me through many nights under the stars.
Switching to a full frame ASI6200MM,a fantastic but demanding camera, pushed me to upgrade my wide-field setup… and new things are coming soon.
For the processing, not only PixInsight: Photoshop has now become a stable part of my workflow, perfect for quickly and effectively refining those small details that make all the difference.
Clear skies, everyone!
IC 1396 is a large ionized gas region in the constellation Cepheus, approximately 2,400 light years from Earth. The Elephant Trunk nebula is a concentration of interstellar gas whose rim is illuminated by the bright star HD206267. The Elephant's Trunk is believed to be a region of star formation, and two very young (1 million years old) stars sit in the cavity at the top of the trunk.
This image was taken using Sulfur 2, Hydrogen Alpha and Oxygen 3 filters which are mapped to Red, Green and Blue channels respectively, resulting in this Hubble Palette image. The final image comprises a total of almost 20 hours of data under the dark skies of West Virginia.

The Wolf’s Cave Nebula (VDB 152) in Cepheus is a dark and reflection nebula set within a vast molecular cloud. Its ghostly structure emerges from obscuring dust, faintly lit by starlight and enriched by emission from different elements. By combining both broadband (RGB, LRGB) and narrowband (Hα, SII, OIII), each rendering offers a unique glimpse into the complex interplay of gas and dust.

Finally finished with this project, and it's my first full SHO narrowband image in the traditional Hubble Color Palette. Getting colors the way you want them is pretty difficult especially via the ColorMask script in PI.
IC1396, or the Elephant's Trunk Nebula, is located in the constellation Cepheus. It is a dark nebula located in the middle of the emission region, and is now thought to be a star-forming region.
This image is a full SHO narrowband image totaling about 35.5 hours of exposure.

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.

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.

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.

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.
With the sun coming out for the train, 37884 Cepheus trundles past Bordesley Junction with 5Q42 Long Marston to Crewe IEMD, with ex-TfW 769421 in tow.
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.

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.
The Iris Nebula in Cepheus is a reflection nebula illuminated by its enveloped central star. This LRGB image was captured on the evenings of 2017-05-26 and 27 at Brooks Memorial State Park near Goldendale, WA. Telescope: William Optics ZenithStar 110mm. Camera: QSI 683wsg. Mount: iOptron iEQ45 Pro. Integration Time: 105 mins for Luminance and 85 mins each for RGB.
Framed nicely by the OHLE gangtry, a shot ive been wanting to do for a while, but alas I now wish id of done this before the wires went up as 37884 Cepheus passes through Taplow with 321348+442 in tow for scrap working 5Q76, Parkeston HS-Newport.. seconds after this passed the sun went behind some encroaching cloud
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.

NGC7023 - or the Iris Nebula - is a bright reflection nebula, in the constellation Cepheus, 1,300 light years from earth. The blue colour comes from the star reflecting in the centre which is a young, hot magnitude +7 star.
This is my first-ever stacked and processed deep sky telescopic astro photo (taken via iTelescope). I still have a lot to learn but I was pretty happy with how this turned out for a basic first attempt.

The Elephant's Trunk Nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth. The piece of the nebula shown here is the dark, dense globule IC 1396A it is commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths.

Here it is my Bi-colour Hubble version of NGC 7635 Bubble Nebula, Oiii and Ha only!
Well this probably the last image I process before the "2017 Astro Festival weekend" at Herstmonceux this coming Friday (1st Sep). This will be the first time working there on the "Telescope House" Exhibit.
Note:
I add the Ha stars back in near the end of the process, given me smaller stars and no colour Halo's....

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.

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.
