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.

Due to a blazing bright moon on Sunday evening I decided to try and image the iconic Horsehead Nebula in Orion using my narrowband Hydrogen Alpha (Ha) filter.
The first time I have imaged this nebula!
The Horsehead Nebula is a small dark nebula situated just south of Orion's belt and close to the bright star Alnitak, the eastern most star of said belt.
The nebula is approximately 1375 light years from earth and gets its name from its resemblance to a horse's head or a knight chess piece! Although the more I look at it it reminds me of a Seahorse!
The deep red colour originates from ionised Hydrogen gas (Ha) behind the nebula. The energy source being the nearby star Sigma Orionis.
Visible foreground streaks within the ionised gas are due to magnetic forces channelling the gas into streams.
The background strip of glowing hydrogen gas marks the edge of an enormous cloud.
Heavy localized interstellar clouds of dust result in alternate areas of almost complete opacity and transparency within the Horsehead.
The darkness of the Horsehead is caused by this dark, thick dust blocking the starlight behind it.
Imaged with an Esprit 120ED refractor and a ZWO 1600MM camera/Baader Ha filter combo.

First time to actually try to process the Horsehead. Such a classical image. What to do with it. Somewhat a Christmas touch. The Orion is the thing that I always look for in the sky during the winter period. Always amazed by the beauty of the constellation and something I have wanted to have as an image on the wall. Here captured from Oria in Spain, 131 frames 300s SHO. Yes traditional processing but still satisfied my expectations.
come avevo promesso, abbiamo insistito su quest'oggetto in 3 diverse serate, di cui una in piacevole compagnia dell'amico ed astrofotografo Giorgio Ferrari ( www.flickr.com/photos/137658783@N07/ ) e la dolce compagna che ci hanno coccolato e che salutiamo affettuosamente ♥ :)
In questa ultima versione sono apparse più nitide le nebulosità più deboli intorno alla nebulosa Fiamma, a sinistra della grande stella Alnitak, e sotto l'arcinota nebulosa oscura "Testa di Cavallo", a destra.
Per un totale di poco più di 8 ore, ho selezionato 7 ore di best-frames, realizzati il 26 Novembre, il 31 Dicembre 2016 ed la notte tra il 4 ed il 5 Gennaio 2017.

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 Nebula (also known as Barnard 33 and IC434 ) is a dark nebula in the constellation Orion. 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.
It is located approximately 1500 light years from earth. The Flame Nebula, designated as NGC 2024 and Sh2-277, is an emission nebula on the lower left of the central horsehead.

This is probably one of the most identifiable objects in our skies. It’s located in the constellation Orion, a summer time object for us in the Southern Hemisphere. About 1500 light years away, it has a striking resemblance to a horse’s head in silhouette. Barnard 33 is a diffuse dark nebula, and its shape is simply the result of dust obscuring a direct line of sight to the bright red emission nebula IC 434. It’s incredible how an absence of light can yield something awesome. I love the star in the lower left. In my head, it appears to be a vortex or tunnel is forming straight out of a SciFi movie.
I used Ha filter to create this image, highlighting the glowing ridges and curtains of light in the top.

Here is a wide field shot of one of the most photographed objects in the night sky, the Horsehead Nebula. The Horsehead Nebula is a diffuse dark nebula in the constellation Orion. The Horsehead Nebula is also referred to as Barnard 33 and is located inside the emission nebula IC 434 (the reddish background), it lies about 1,500 light-years away. The bright star to the left of the Horsehead Nebula is actually the star Alnitak, the leftmost star in the belt of Orion.

Captured using ZWO AAP and processed using PixInsight. Autofocus was accomplished using the ProAstroGear Black-CAT and ZWO EAF. Image date: January 31, 2022. Location: The Dark Side Observatory, Weatherly, PA, USA (Bortle Class 4).
Orion's belt holds a slew of celestial treasures including famous Horsehead and Flame Nebulae. With them being so big, bright, and full of colors, it's no wonder this area is so popular. I've already been thinking about another effort to shoot this area with a different telescope so I figure should probably finish up this one first. From my home in Colorado, I shot 30 images from an observatory in Mayhill, New Mexico over 2 nights using iTelescope's T68 telescope.
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 Horsehead Nebula (also known as Barnard 33 ) is a dark nebula in the constellation Orion.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 nebula was first recorded in 1888 by Scottish astronomer Williamina Fleming on photographic plate B2312 taken at the Harvard College Observatory. The Horsehead Nebula is approximately 1500 light years from Earth. It is one of the most identifiable nebulae because of the shape of its swirling cloud of dark dust and gases, which bears some resemblance to a horse's head when viewed from Earth. - (Wikipedia)
Deepest Image of Universe Yet
Planet Impero
Interplanetary Travel
I fall asleep enchanted by the immense landscape of a distant universe. There are no words to describe the deep peace I felt in front of this view. In front of this magnificent view, I forget that I am even alive. It's like I'm not alive. It's like there's no time. I am in deep silence.
These are my last days on this planet that I'm exploring. I started making preparations for my next space trip. Soon I will be traveling through deep space again to discover a new planet and find the plunonians.
Keep following me.

This is the Horsehead Nebula (AKA Barnard 33 and IC434), with the Flame Nebula and Alnitak.
These object were exposed with a cooled and full spectrum modded DSLR through a 8" SCT at f6.3 for 16 hours and 16 minutes.
I kind of messed this one up. Half of my 30 minutes of exposures had streaks on them due to the tracker load being unbalanced. And several had a bad internal reflection from the brightest star due to the UV filter I forgot to take off. But it was still acceptable enough for web viewing.
Live and learn!

Another image of one of the most popular objects imaged by astroimagers... The Horsehead Nebula/Barnard 33 with Alnitak and the Flame Nebula, but exposed mainly through narrowband filters, but emulating natural colors of the object.
I was planning to combine H-Alpha as red, OIII as green and H-Beta as blue channels to create a natural colour image through CCD narrowband filters, eliminating any light pollution or moon sky-glow in the process.
Unfortunately, the last night when I was able to do any imaging of subs for this object was on the 20th February before it became cloudy every day and night with constant rain, when I managed to get only 3 x 30 minute H-Beta and 4 x 20 minute OIII narrowband subs.
After waiting for a couple of weeks, I figured that I'm not going to get much decent exposure time on Barnard 33 before it become obscured by landmarks so I decided to combine my currently exposed subs.
This image total exposure time was 9 hours and 32 minutes, channels consisting of 15 x 600 second H-Alpha, 4 x 1200 second OIII and 3 x 1800 second H-Beta 7nm narrowband subs with only 25% intensity added from the 14 subs each through red (180s), green (300s) and blue (600s) filters.

The Flame Nebula NGC 2024 or Sh2-277 is an emission nebula in the constellation Orion. Located in the Milky Way it is about 1,500 light-years away.
The bright star Alnitak beneath the nebula shines energetic UV-light into the Flame and ionises the great clouds of hydrogen gas that reside there. Much of the glow results when the electrons recombine there.
Additional dark gas and dust lies in front of the bright part of the nebula and this causes the dark network that appears in the center of the glowing gas.
Beneath the center of the frame you can also find the famous Horsehead Nebula.

A Hydrogen-Alpha (Hα) study of IC 434, 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 background story:
I was fortunate enough to get a little bit of precious Telescope imaging time at an Observatory with the kind of Astrophotography gear that I can only dream about. We decided that the name of the Observatory and gear would remain secret, as it is of no importance for my personal research.
There was not enough time to do justice to a spectacular exotic Deep Sky Object (DSO), so I decided to do a practical test of a very well-known DSO (for purposes of comparison in the little time I had).
I chose to image in 3nm Hydrogen-Alpha Narrowband (at the wavelength of 656.3 nm). I did star removal during image processing, as I was interested in the detail that one could capture in the Hydrogen emission of the nebula (in a relatively short amount of time, in near perfect weather conditions with great equipment).
The short answer: Yes, there is a huge leap in imaging quality, but it comes at a price!
A quick calculation puts the difference in price between Amateur Astronomy and Scientific grade equipment at roughly 10-20 times the cost. I thought it would be a worthwhile experiment to see how much quality difference there was, when using "top of the range" Astronomical equipment (that one would probably only be able to afford if you received Scientific funding).
Who knows, one can always dream...

One of the most popular object for astroimagers... The Horsehead Nebula/Barnard 33 with Alnitak and the Flame Nebula.
As I continue to have terrible sky conditions for astroimaging, I'm struggling to complete any images before the imaged object season is finished. Seems like my nights are perpetually cloud covered.
I'm keeping an eye on the sky, and when I spot some clarity, I immediately open the observatory and start to gather photons.
I captured this image by noticing that there was a clear window of opportunity and managed to have a couple of hours of clarity before clouds returned.
I captured another hour worth of exposed H-alpha subs which smoothed out some noise in the shadows but I also would like to capture other color channels and create a color photo... but with the weather being against me, I'm running out of time.
This images total exposure time was 2 hour and 30 minutes, consisting of 15 x 600 second 7nm narrowband H-Alpha subs.

Nebulosa da Cabeça de Cavalo e Nebulosa da Chama
[English Below]
Exercício (tentativa de registro prolongado), somando frames de dois dias (isto pela primeira vez), com a Nebulosa da Cabeça de Cavalo (Barnard 33) e a Nebulosa da Chama (NGC 2024). Foram empilhados 35 frames, totalizando quase 3 horas de exposição. Dentre outros fatores, infelizmente os registros foram um pouco prejudicados pela poluição luminosa da Lua e por algumas nuvens passageiras (não pude aguardar por dias mais favoráveis em razão de Órion já estar se despedindo do meu campo de visão nesta temporada). Também desta vez, senti necessidade de ter feito mais frames para alcançar melhor resultado, mas um novo período de noites com tempo fechado se iniciou. Fica para a próxima temporada. Ainda buscando avançar no processamento.
À direita da imagem, está a famosa Nebulosa da Cabeça de Cavalo. A Nebulosa da Chama está na parte inferior esquerda da imagem. Ambas se situam na constelação de Orion. A Nebulosa da Cabeça de Cavalo é uma nuvem de poeira opaca e é vista contra um brilhante fundo vermelho da nebulosa de emissão que se originou de uma nuvem de gás hidrogênio. A Nebulosa da Chama, é energizada por altos níveis de luz ultravioleta emanando da estrela supergigante azul Alnitak, mostrada logo acima dela, que é a estrela mais a leste no Cinturão de Orion.

====================================
Exercise (extended registration attempt), integrating two-day frames (this for the first time), with the Horsehead Nebula (Barnard 33) and the Flame Nebula (NGC 2024). 35 frames were stacked, totaling almost 3 hours of exposure. Among other factors, unfortunately the records were somewhat damaged by the light pollution of the Moon and some passing clouds (I couldn't wait for more favorable days because Orion is already saying goodbye to my field of vision this season). Also this time, I felt the need to have made more frames to achieve a better result, but a new period of nights with closed sky started. Stay for the next season. Still looking to advance in processing.
To the right of the image is the famous Horsehead Nebula. The Flame Nebula is at the bottom left of the image. Both are located in the constellation of Orion. The Horsehead Nebula is a cloud of opaque dust and is seen against a bright red background of the emission nebula that originated from a cloud of hydrogen gas. The Flame Nebula is energized by high levels of ultraviolet light emanating from the blue supergiant star Alnitak, shown just above it, which is the most easterly star in the Orion Belt.

One of the most popular object for astroimagers... The Horsehead Nebula/Barnard 33 with Alnitak and the Flame Nebula.
This images total exposure time was 6 hours and 42 minutes, consisting of 16 x 600 second 7nm narrowband H-Alpha and 14 subs each through red (180s), green (300s) and blue (600s) filters.
Taken through a 80mm Refractor @ f6.25, on a hypertuned CGEM mount with QHY268M camera.
In late summer 2019, I got a STC Duo-Narrowband filter which allows only light from 2 very narrow bands of the EM spectrum - Hα and OIII. I've shot some pretty cool stuff with it, but always processed the image as a RGB image, since that's what the camera produced. And I've been pretty happy with doing things that way.
Then I discovered that you could extract Hα and OIII components of that RGB image separately to monochrome images while stacking with AstroPixel Processor. This results in images much like what you would get using a monochrome camera plus either an Hα and OIII filter separately.
This is the result of the Hα component.

Hi Folks,
This is image is a little different - I would classify this as a "Failed Image" - and I am sharing it as I feel there is still much to learn from bad images.
This is an image of the Horsehead (B33) and The Flame Nebula (NGC 2024) and is the result of wideband and narrowband data collected during the incredible stretch of weather we just had in western NY November 5-8, 2021.
I ended up getting in 4 nights of capture on 3 scopes and collected data on 9 Targets!
This is the fifth image I have been able to process from this trove of data and had an integration 4.7 hours.
This was taken with my William Optics 132mm FLT APO scope, the IOptron CEM60 mount, and the ZWO ASI1600MM-Pro camera.
This is the second image from that capture session to have halos and microlens reflection artifacts due to having a bright star in the field. In the first image, IC 63, I was able to find a technique to correct that problem and create a nice image. However, this image had more complex halos and microlens reflections than the first and I was *not * able to process the image to correct these artifacts in a way that I find acceptable.
I can say that I will not be using this scope/camera combination again for any targets with bright star in its field!
When I first created my website I committed to sharing all of my images - both good and bad. The journey of astrophotography will include both and there is something to learn from each. So I share this with that intent in mind.
See the Full details on the capture and extensive processing notes with screen grabs for this image which is available on my website at the link below:

Please check it out and let me know if you have any questions.
Thanks for looking!

The Horsehead Nebula is a diffuse dark nebula in the constellation Orion. The Horsehead Nebula is also referred to as Barnard 33 and is located inside the emission nebula IC 434 (the reddish background), it lies about 1,500 light-years away. The bright star to the left of the Horsehead Nebula is actually the star Alnitak, the left most star in the belt of Orion.

The iconic Horsehead dark nebula in Orion (Barnard 33). Backlit by the extensive billowing clouds of excited hydrogen gas in emission nebula IC 434.
This was a narrowband image comprising 6 x 6 minute exposures on the T21 scope in New Mexico.
Hydrogen alpha filter used.
Planewave CDK430mm aperture. 1939mm focal length at f/4.5
From the resulting black and white image which was integrated in PixInsight, I used a gradient map in Photoshop to add false colour.
Another trip into space, this time to Orion that, at present in the UK, rises above the horizon late in the evening in the east and is visible higher up in the sky from midnight onwards. The Horsehead Nebula is an iconic dark nebula in the Orion constellation. Along with the nearby Flame Nebula (to the left in the image) they are part of the much larger Orion Molecular Cloud Complex. Compared to some nebulae, this one is very easy to find - it is located near the most eastern star in Orion's Belt, Alnitak and is 1500 light years from Earth.

Narrowband image of the Horsehead Nebula in Hydrogen Alpha.
Located 1600 light years away in the constellation of Orion.
For this image I decided to remove the stars using the RC Astro Star Xterminator plugin. I think it has done a pretty good job even with the troublesome star Alnitak!

The Flame Nebula, seen to the left of this image, seems to have ignited the entire region in Orion. The Horsehead nebula is actually a dark nebula (Barnard 33) against the bright backdrop of nebula IC 434. The bright star between the Flame and the Horsehead is Alnitak, the leftmost star in Orion’s belt. North is to the left in this image. Visually, the Flame is an easy target in a moderate aperture telescope; the Horsehead is very difficult and requires an H-Beta filter and very dark skies.
