Conditions were not great, with haze and clouds passing through but I was eager to get out under the stars. A heavy fog rolled in as I was shooting the dark frames about an hour before sunrise. Looking forward a chance to see what I can do with this lens once conditions improve this winter.
The Horsehead Nebula is a small dark nebula in the constellation Orion. The nebula is located just to the south of Alnitak, one of the bottom stars in Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex.

IC434 Horsehead Nebula and NGC 2024 are located in the constellation of Orion. The bright star to the left of the horsehead is Alnitak, the first of the three stars that make up Orions belt. This image was made up of a combination of Red Green and Blue using a colour camera with a UV/IR filter and the Red channel of a narrowband filter to enhance the hydrogen gas in the nebula.
Imaged from my home in Gergal, Spain over 6 nights in January and February 2023.

The Horsehead Nebula (also known as Barnard 33) is a dark nebula in the constellation Orion. The nebula is located just to the south of Alnitak, the easternmost star of Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex.
The Horsehead Nebula is approximately 1500 light years from Earth. It is one of the most identifiable nebulae because of its resemblance to a horse's head.
The Flame Nebula, designated as NGC 2024 and SH2-277 is an emission nebula in the constellation of Orion.
The bright star Alnitak, the easternmost star in the Belt of Orion, shines energetic ultraviolet light into the Flame and this knocks electron away from the great clouds of hydrogen gas that reside there.
The Running Man Nebula Sh2-279 is an HII region and bright nebulae that includes a reflection nebula located in the constellation Orion. It is the northernmost part of the asterism known as Orion's Sword, lying north of the Orion Nebula. The reflection nebula embedded in Sh2-279 is popularly known as the Running Man Nebula.

The Horsehead Nebula, also known as Barnard 33, is a dark Nebula in the constellation Orion. The Nebula is located just to the south of Alnitak, the easternmost star of Orion's Belt and is part to the much larger Orion Molecular Cloud Complex.
The Nebula was first recorded in 1888 by Scottish astronomer William Fleming on a photographic plate taken at the Harvard College Observatory. The Horsead Nebula is approximately 1500 light years from Earth. It is one of the most identifiable nebulae because of its resemblance to a horse's head.
Due to its recognizable shape the Horsehead Nebula is one of the most famous celestial objects.
The Flame Nebula, designated as NGC 2024 and SH2-277, is an emission nebula in the constellation of Orion. It's about 900 to 1,500 light-years away
The bright star Alnitak, the easternmost star in the Belt of Orion, shines energetic ultraviolet light into the Flame and this knocks electron away from the great clouds of hydrogen gas that reside there. Much of the glow results when the electron and ionized hydrogen recombine

This rather complex nebula region of Orion is quite challenging and I am not able to adequately capture it to my satisfaction so thus another attempt.

My first post of the year is one of the most challanging panoramas I shot so far. It is my first tracked panorama shot at 70mm focal length and was captured in one of my favorite places, at the Tschuggen Observatory in Arosa, Switzerland. Despite the rather narrow final field of view, it consists of 18 panels for the foreground and 4 panels for the sky.
Capturing the set of exposures in freezing-25°C was quite an ordeal for me and my equipment. Eyeballing the overlap and moving the camera on my frozen up ballhead and with my numb fingers proved almost impossible and these equipment problems made my buy a good panorama head a few weeks later…
Processing the panorama proved to be tough on my computer as well. The photoshop file of the 200 megapixel panorama has whopping 31GB, but the resolution and detail I recorded in the sky is amazing.
The Orion, Runnning Man, Flame and Horsehead nebulas are beautifully resolved and the hydrogen alpha nebulosities in the region are standing out nicely: Barnards Loop, the Meissa Region, the Rosette Nebula, the Seagull Nebula and the Christmas Tree Cluster are really popping.

Alnitak, the 5th brightest star in the Constellation Orion, is the star to the left (from our view) of the triad of stars in the belt. It has two large nebulae, the Flame Nebula and the Horsehead Nebula. The Horsehead Nebula is a cloud of dark, cold gas seen against the large Orion molecular cloud complex. The Flame Nebula is an emission nebula--it absorbs energy from nearby stars, which releases an electron from gaseous hydrogen atoms. When an electron is replaced, light is emitted, causing the cloud of hydrogen atoms to glow.
Forty photos were taken (ISO 10,000, 560 mm, f/8.0, 60 sec) with the aid of an Ioptron SkyGuider to track the stars. Starry Sky Stacker was use to rotate the stars to reduce streaking and minimize long exposure and high ISO artefacts. Photoshop and Topaz Denoise AI were used in processing.

This deepscape image shows the sword of Orion rising over a scenic mountain formation in central Switzerland. The famous Orion Nebula, the Horsehead and Flame Nebula and part of Barnard's Loop are coloring the sky in a stunning way.
Deepscapes are an attempt to take landscape astrophotography to the next level. This image is not a digital art collage of an unrelated sky and foreground, but a real alignment. A snowshoe hike with a mobile deep sky imaging rig to a carefully planned site on a mountain slope was required to capture this scene. Foreground and sky were captured back to back during the same night and from the same tripod position.
Capturing and processing the image required both deep space and landscape astrophotography techniques. The foreground and RGB color image of the sky were captured with an astro-modified Canon EOS 6D and a 200mm lens. The sky image was enhanced with 55min of H-alpha data captured with a cooled monochrome astrophotography camera through a narrowband filter.

Adjacent to the star Alnitak (ζ Ori) in Orion's Belt are the Flame Nebula (NGC 2024) and the Horsehead Nebula (part of IC 434). I have color data on this region from several nights, but finally made an effort to add some hydrogen-alpha data. This is from an additional 18 4 min exposures with the Atik 414-EX on the Celesctron Edge HD 925 with Hyperstar.
Processing in the vicinity of such a bright star is a challenge. I think I went between Photoshop and Pixinisight the right number of times for a good result.
The famous Horsehead Nebula is a deep sky gem that needs little introduction. It's a dark nebula made of of cloud of dark dust wich obscures a part of the ionized emission nebula IC 434 behind it. It obviously gets its name from looking strikingly similar to a horse's head
The Flame Nebula to the bottom left is also aptly named for what it resembles. It's a large star formation region filled with custers of young stars that are hidden away in visible light, but illuminate the surrounding clouds of gas and backlight the contrasting dark nebulae running through it.

The Horsehead (center) and Flame (lower left) Nebulae, IC 434 and NGC 2024 respectively in the constellation Orion as imaged by a Vaonis Vespera (Classic) smart telescope using a dual band H-alpha and O-III filter in a Bortle 7 zone, 659 stacked exposures in a composite mosaic (Vespera CovalENS) of 534 frames, with post processing in Adobe CS5 and Luminar Neo with noise reduction using Topaz Denoise AI.
The bright star at left center is Alnitak, a hot blue supergiant, approximately 33 solar masses and 20 times the radius. It is accompanied by two companions making this a triple star system. It is also the leftmost star in Orion's Belt.
Alnitak shines energetic ultraviolet light into the Flame and this knocks electrons away from the great clouds of hydrogen gas that reside there. Much of the glow results when the electrons and ionized hydrogen recombine. Additional dark gas and dust lies in front of the bright part of the nebula and this is what causes the dark network that appears in the center of the glowing gas. The Flame Nebula is part of the Orion molecular cloud complex, a star-forming region that includes the Horsehead Nebula.

The Horsehead Nebula is a dark nebula in the constellation Orion and is approximately 1500 light years from Earth. The dark cloud of dust and gas is a region in the Orion Molecular Cloud Complex where star formation is taking place. The darkness of the Horsehead is caused mostly by thick dust blocking the light of stars behind it. Bright spots in the Horsehead Nebula's base are young stars just in the process of forming. The Flame Nebula (NGC 2024) can also be seen to the left of the image. (Wikipedia)

IC 434 is a bright emission nebula in the constellation Orion. The Horsehead Nebula (also known as Barnard 33) is a dark nebula silhouetted against IC 434.
The red glow originates from Hydrogen gas predominantly behind the nebula, ionized by the nearby bright star Sigma Orionis. Magnetic fields channel the gases leaving the nebula into streams, shown as streaks in the background glow. A glowing strip of hydrogen gas marks the edge of the massive cloud.
The nebula is located just to the south of the star Alnitak, which is farthest east on Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex. The Horsehead Nebula is approximately 1,500 light-years from Earth. The darkness of the Horsehead is caused mostly by thick dust blocking the light of stars behind it. This stellar nursery contains organic and inorganic gas and dust, including complex organic molecules.
The bright blue stars are still surrounded by nebulosity (gas and dust that they form out of), as they are still "young" energetic hot stars. You will notice that star colors differ from blue to yellow, orange and red. This is an indication of the temperature of a star's Nuclear Fusion process. This is determined by the size and mass of the star, and the stage of its life cycle. In short, the blue stars are hotter, and the red stars are cooler.
The nebula in the bottom left corner is called the Flame Nebula (NGC 2024).

The Flame Nebula (NGC 2024) with a photobomb by the Horsehead Nebula (Upper right) found in the Orion constellation and part of the Orion Nebula. The Large bright star above the Flame Nebula Is Alnitak the easternmost star of Orion's belt. This image is a composite using a one-shot color camera (RGB) combined with H alpha narrowband with about 4 hours of data collected.
There are two things seasoned nightscape photographers tell the aspiring beginners:
1. Shoot as wide as possible and
2. The best time to do nightscapes is from spring to fall, when the core of our galaxy is visible.
And here am I, in the middle of winter, hauling my equipment up a steep trail, hating myself for leaving my Canon 70-200mm lens in the backpack - 1.5 kg of useless glass I could easily have left at home!
Really? After hauling it up the hill, I thought I might as well use my heavy lens. I therefore installed my camera on my iOptron Skytracker and shot this 3 panel vertical panorama of the constellation Orion rising above the Swiss Alps.
The resulting image proves the introduction wrong:
1. A zoom telephoto lens is the perfect choice for nightscapes, if you can track the sky
2. Winter with Orion’s colorful nebulas is at least as good for nightscapes as the Milky Way "core" season.

This was an end of session image and to see what this camera can do with just 3min exposures. The seeing was not good but better than it was earlier.
The Stars are not good and bit of a blue edge round the star Alnitak but I've spent far to long on this already, might try and sort this out later.

My first successful astro mosaic! It's a total of 380 minutes of imagery, 11 different panels, so panel integrations average 34 minutes. The Orion, Running Man, Horsehead, and Flame Nebulae area has the most imagery behind it, as well as the Witch Head Nebula.
Imagery was acquired in 2019 and 2020 on 9 different nights from the same location under rural skies (Bortle 3/4). All subs were taken with my Fuji X-T10 and Samyang 135 mm on the iOptron SkyTracker Pro. Each sub is 60 seconds, taken at ISO 1600 with the Samyang 135mm open to f2.
I integrated individual panels using DeepSkyStacker, and used the 'remove light pollution' tool of Astro Pixel Processor to flatten integrations, which had substantial vignetting from being shot at f2. These flattened panels were then mosaiced with Astro Pixel Processor using the process outlined here: www.astropixelprocessor.com/part-3-register-normalize-int.... Curves adjustment, star reduction, and color tweaking were then done with GIMP. This image is downscaled 50%.
It's not a perfect process and the data has issues, but I'm happy with the result. It was fun to explore the less-imaged nebulosity between the Orion and the Witch Head Nebulae, and around Saiph.
I'm sure I'll keep tinkering with this, and I still plan to shoot the entirety of Orion this winter, but this is a nice mosaic in and of itself, so I wanted to post it.
Aug. 2021 update: I've been looking through my astro photos, ramping up for some imaging this fall and winter (hopefully I'll complete this Orion mosaic). I decided this image could use a little lightening.

The constellation of Orion needs no introduction. It's a rich area encapsulated by a molecular cloud and featuring some of the most destinct and most popular nebulae the night sky has to offer. These nebulae are popular targets for amateur visual observers with binoculars and small telescopes, particularly the great Orion Nebula (M42) and its immediate companion, the Running Man Nebula. But others are far fainter and benefit from large aperture telescopes or long exposure photography, such as the Horsehead, Flame and Witch Head Nebulae, and smaller, faint nebulae, many of which are represented in this field of view.
This is my first deep sky image produced with my new Nikon Z6ii. It's similar to a surprisingly good test image that I shared some weeks ago shot with my D750, only now with the constellation much higher, I didn't have horizon glow and treetops to crop out. And since the constllation is up much earlier, I didn't have to cut my night short. I would have actually gotten more exposure time but unfortunately the battery in my SkyGuider Pro died after 150 minutes, putting this session to an end. But overall, I'm very pleased to be able to share what I consider by far my best wide field image of this constellation to date.

The horse head nebula in Orion. This was a tough one to process. Alnitak kept taking over the photo. Next time out I will take shorter exposures on the blue and green filter.
Taken with a ZWO ASI1600mm-cool, R=12 @ 240 sec , G=25 @ 120 sec, B= 45 @ 60 sec, HA=15 @ 240 sec. Clouds moved in before Luminance were taken. Default HDR gain setting. Edit with Pixisight. Taken Nov. 2018
NGC 2024 Flame Nebula and Banard 33 Hornsehead Nebula. - 102 1 minute f/6.3 ISO 1250 at 500mm with crop.
The region around the Horsehead Nebula (IC 434) and the Flame nebula in constellation Orion is dominatred by dramatic hydrogen alpha emission colors and blue reflection colors of bright stars. This color version is a combination of hydrogen-alpha data shot with a Baader 7nm filter and RGB data.

This RGB image was taken with the Grand Mesa Observatory System 1 scope - a Takahashi FSQ130 scope with a QHY600M camera which captures great detail in targets.
Although this image was centred when captured on the Horsehead nebula - it just struck me that there was great detail and beauty in the dark clouds of the Flame nebula and also the 4 bright nebulae surrounding the Flame so I've made the Flame, or Burning Bush nebula the centrepiece.
