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!
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.

Description:
These elusive nebulae have low brightness and contrast, and are difficult to photograph, requiring a very dark sky in a non-light polluted observing site.
(North is to the left in this image.)
From Wikipedia:
"NGC 7822 is a young star forming complex in the constellation of Cepheus. The complex encompasses the emission region designated Sharpless 171, and the young cluster of stars named Berkeley 59. The complex is believed to be some 800–1000 pc [2,500 - 3,300 light years] distant, with the younger components aged no more than a few million years."

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.

The Cave Nebula (Caldwell 9, Sh2-155) is a diffuse emission nebula within a larger nebula complex that includes a reflection nebula, and dark nebula. This deep-sky object is located in the constellation Cepheus and lies roughly 2,400 light-years from Earth.
This was imaged over the past few weeks from my rig at Starfront. I believe this is the first time I shot it.
I haven't done a SHO color palette in a while. I felt this palette really brought out the OIII blue vs the others that were primarily red.

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 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.
The Double Cluster in Perseus is at the top center of the image, and Ursa Minor is in the lower right portion. The Andromeda Galaxy (M31) also appears just at the top of the image, left of center. The main constellations along the Milky Way in this view are Cassiopeia and Cepheus.
This latest process of mine (part of a set of 2 images of SH2-171) from Grand Mesa Observatory was captured using the QHY367C for Color and for Narrowband I processed as Hubble Palette and I used the stars from the RGB image.

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.
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.

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.
I wasn’t happy with previous version, so i reedited this widefield.

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.
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.

Rail Operations Group Class 37 37884 'Cepheus' passing Chesterfield returning from Barrow Hill L.I.P. to Derby R.T.C at 1402 on the 20th May 2022
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.
Calibration, Registration, Integration in APP, further processing to taste in PS.
The viewing conditions were not as good as was hoped (Rhön, Germany) with intermittent thin cloud and dew that fell with a particularly heavy "thud" 😉 , still most of the data was usable ...

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.
