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, where there is a dark patch with a bright, sinuous rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright, massive star (HD 206267). The entire IC 1396 region is ionized by the massive star, except for dense globules that can protect themselves from the star's harsh ultraviolet rays.
The Elephant's Trunk nebula is now thought to be a site of star formation, containing several very young (less than 100,000 yr) stars that were discovered in infrared images in 2003. Two older (but still young, a couple of million years, by the standards of stars, which live for billions of years) stars are present in a small, circular cavity in the head of the globule. Winds from these young stars may have emptied the cavity.
This is a mono image taken in Ha, that I hope to add colour to when the conditions allow.

Is everyone ready for Halloween? Here are some ghosts and a bat overhead to help you get ready!
Better known as the Ghost Nebula, SH2-136 a reflection nebula located in the constellation Cepheus. It is referred to as a Bok globule (relatively small dark nebulae, containing dense cosmic dust and gas from which star formation may take place). The embedded stars make it glow a brownish color.
Revisited this earlier target to add some data and new processing techniques. I'm not sure how this looks like a lions head :D But it doesn't matter. These descriptive names do wonders for helping me recognize previous projects but unlike constellations who's names and description give me a sense of connection with humans of bygone eras these modern deep sky object names seem a bit silly to me ;)
"The Lion's Head Nebula, also known as Sharpless 2-132, is a lesser-known but intriguing nebula located in the constellation Cepheus. This emission nebula features ionized gas illuminated by the ultraviolet light from nearby hot stars, which gives it its glowing appearance. The nebula’s resemblance to a lion’s head, from which it derives its name, is seen in the intricate patterns and structures of gas and dust within it.
Key Features:
Distance and Size: Located at a distance of approximately 10,000 light-years from Earth, the Lion's Head Nebula spans several light years across. The exact size can vary depending on the boundaries defined by observations in different wavelengths.
Composition: Primarily composed of hydrogen gas, it also contains traces of other elements such as oxygen and sulfur, which add to the variety of colors typically seen in images—reds from hydrogen, greens from oxygen, and blues from sulfur.
Star Formation: The nebula is a site of active star formation. Dense clouds of gas and dust within the nebula collapse under their own gravity, leading to the birth of new stars. These young stars often emit strong stellar winds and ultraviolet radiation that further shape and ionize the surrounding nebula.
Observation: The Lion’s Head Nebula can be a challenging target for amateur astronomers due to its faintness and the need for dark skies away from light pollution. It is best viewed through medium to large telescopes equipped with cameras capable of long exposure times to capture its faint details.
Scientific Interest: Astronomically, the Lion's Head Nebula is of interest due to its active star-forming regions. Studying such nebulae helps astronomers understand the processes of stellar evolution and the dynamics of interstellar matter. The structures within the nebula, such as pillars and globules, can provide insights into the effects of stellar winds and radiation on nebular material.
Overall, the Lion’s Head Nebula represents a beautiful example of the dynamic and ongoing processes in our universe that lead to star formation and the sculpting of cosmic landscapes." synthesized from various sources

The “Ghost Nebula” (designated Sh2-136, VdB 141) is a reflection nebula located in the constellation Cepheus.
It lies near the star cluster NGC 7023. The Ghost Nebula is referred to as a globule (catalogued CB230) and over 2 light-years across. There are several stars embedded, whose reflected light make the nebula appear a yellowish-brown color giving it the eerie “ghost-like” appearance. The surrounding region is filled with interstellar dust and gas.

**Note**
I've reprocessed the Ha luminance to tone down the stars and soften the image while keeping the detail around the cave.
Well I managed to image this over one night between 22:45 and 3:45. I was going to add more Ha/Oiii to reduce the noise but by the time I got a another clear night the moon was back. The Oiii was very faint and I had to stretch it to destruction which made it very noise. As there was no detail in the Oiii (all detail comes from the Ha) I used a Gaussian Blur of 20 which solved the problem.
Object Description:-
SH2-155 (Sharpless 155) the Cave Nebula is made up of a combination of areas of emission/reflection/dark Nebula. It lies in the constellation of Cepheus at a distance of approximate 2,400 ly with a visual mag of 7.7. The Cave refers to the area of ionized Ha where star formation is actively ongoing.
Notes:-
1. This is not very strong in Oiii so I used a gain of 200 to obtain the Oiii subs.
2. To get the colour neutral stars without halos I used a "Starless" Oiii and Ha images but used an Ha Luminance which include the Stars.

One of my favorite regions of the sky - the Dark Shark Nebula (LDN 1235), LDN 1251, and the Wolf's Cave Nebula (vdB 152). It's a tricky region to process - the dust is faint and the stars are plentiful. If I shoot this again with the my Samyang 135, I think I'll stop down to f 2.8 to flatten the field and shoot 90-120 sec subs. I had problems with the not-too-flat field in post processing. I've cropped it to minimize the non-flat-field color artifacts.

Nov. 2020 update: I added my Sept. 26 2019 imagery (50 x 90 seconds, better color) to my 2020 imagery (84 x 60 seconds, better skies). There's still some color weirdness, but the addition of the 2019 with better color helped modulate the color weirdness of the 2020 data. I might still end up cropping it, but at least the color is a bit better. Perhaps I'll shoot this area again next August or Sept.

This was imaged over 2 night both of which were marginal and I could only just make out the Milky Way overhead with a bit of imagination. If the object hadn't been at a reasonable attitude I probably would not have bothered. Saying all that I'm surprised at how much detail came through.

“Reprocessed Image of NGC7023 Iris Nebula”
Original image link:- flic.kr/p/2panefq
This is a rework of NGC7023 Iris Nebula taken with the “Explore scientific 16mp OSC” back in October 2023, this camera was kindly on loan/test from Kerin at Telescope House.
This time I used GraXpert AI to remove the noise. This help me to stretch the image further, this meant I could pull out more of the interstellar dust. I also used Siril “General Hyperbolic Stretch” transformation but this time along with “Human Weighted Luminance” to preserve the colour. I finished the image of using “Affinity Photo 2”. Although this software is similar to Photoshop CS2 and does everything I require and more, it’s going to take me time to work out where everything is.
This is a bright reflection Nebula in the constellation of Cepheus. The nebula, which shines at magnitude +6.8, is illuminated by a magnitude +7.4 star and lies 1,300 light-years away and is 6 light-years across. Its Apparent Dimension is 18' x 18'. The designated No. NGC7023 actually refers to the open cluster within the nebulosity which has it own designation of LBN487.

Sharpless 132 is a very faint emission nebula, it found at the border of the constellations Cepheus and Lacerta - Ra 22h 19m 20s Dec +56° 06′ 00"
Imaged using an Astrodon 3nm Ha & 5nm OIII filters, an Altair Astro 6"RC and Atik 460ex. Processing was completed in Pixinsight and CS5.
This is my 2nd image taken in the Cepheus region of the night sky. I had a few issues earlier on which delayed me for about an hour so I had to stay out later then I wished, 3:00am. Rather than wasting more time with a meridian flip I let it run for an hour pass the Meridian which didn’t seem to cause any issues. This object is faint and would have benefited from an increase in the subs by 1-2 min. As a result of only using 4min subs a lot of time was spent in processing to keep the noise under control.

The zodiacal light (toward the left of the image) was surprisingly bright -- it appeared even brighter than the Milky Way (toward the right of the image) to my eye. Jupiter is the bright object immersed in the soft glow of the dust in our solar system. The Milky Way is seen in the constellations Cygnus, Cepheus, and Cassiopeia.
This was with a Rokinon 8mm fisheye lens on a Nikon D5100 that was modified for astrophotography. I took about 25 exposures for this session, but this was the lucky one where a meteor showed up above the ocean.

Barnard 150 is a dark nebula visible in Cepheus constellation. It is also known as the Seahorse Nebula due to its shape.
The dust nebula cover about 1° of angular dimension. [from Wikipedia]
La nebulosa "Cavalluccio Marino" è un vasto complesso di polveri localizzato nella costellazione del Cefeo. Deve il suo nome alla sua forma che ricorda quella di un cavalluccio marino. Le sue polveri sono talmente dense da nascondere la luce delle stelle che vi si trovano dietro, dandole così la connotazione di nebulosa oscura.

This object is a new one on me which I only heard about this year and is a tough little bugger. I took this around the same time as the Pelican. The sky’s were of average clarity but as this object was high up it didn’t have a big affect on the image. There is a tiny planetary nebula G101.5-00.6 bottom right just above the signature.
FYI To me it looks less like a Lion but more like a T-Rex head on a small dogs body...😁
OBJECT DESCRIPTIONS:-
SH2-132 The Lion Nebula is a an emission (Ha rich area) in the southern most part of the constellation Cepheus and is located approximately 10,000 light years away. The ionisation of the gas in this region is the responsibility of some massive stars, typically Wolf Rayet type. These have a white/blue colourisation and at least 20 times the mass of our own sun. The apparent is 90’ x 90’.

IC 1396 in Cepheus (2025)

IC 1396 is a large emission nebula and star forming region located about 2,400 light-years in Cepheus. It is energized by the bright central multiple star HD 206267.
The name refers properly to the cluster scattered in its center but is extended to the entire nebular region, one of the largest and brightest in the sky.
The orange star is the red supergiant Mu Cephei of about 19 solar masses, perhaps the largest star visible to the naked eye with an estimated diameter of about 1600 times that of the Sun. The estimate comes from its interferometrically measured angular diameter of 18.672±0.435 mas at a wavelength of 800 μm (D. Mozurkewich et al 2003 AJ 126 2502). Mu Cephei is also a variable star.

SH2-115 (mid left) and Sh2-112 (right) are emission nebulas in the constellation Cygnus. The bright round object in the left top of the frame is Abell 71. Abell 71 is still discussed to be a planetary nebula or just an Ha emission nebula. Revison of data from August 2020.

Using the U.S. National Science Foundation National Radio Astronomy Observatory’s (NSF NRAO) U.S. National Science Foundation Very Large Array (NSF VLA), astronomers have revealed for the first time the huge flow of gas near a massive star in the making which allows its rapid growth. By observing the young star HW2 in Cepheus A, located 2300 light years from Earth, researchers have resolved the structure and dynamics of an accretion disk feeding material to this massive star. This finding sheds light on a central question in astrophysics: how do massive stars, which often end their lives as supernovae, accumulate their immense mass?
The Iris Nebula or NGC 7023, is a bright reflection nebula located in the constellation of Cepheus. NGC 7023 is actually the cluster within the nebula LBN 487 and the nebula is lit by a magnitude +7 star. A short break in the clouds so only managed 2 and a half hours integration time but I'm pleased with the detail I managed to capture.

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.
On this wide field image the, elephant trunk is the darker region in the lower third of the image with a lighter rim around it’s dark form. The lighter rim is the surface of the dense cloud that is being illuminated and ionised by a very bright, massive star HD 206267
Taken over three nights at the observatory in Los Coloraos, Gorafe, Spain.
