Orion Nebula, Messier 42 - M42 by Gemma - A Passionate Photographer

519 114

The Orion Nebula is a massive cloud of gas and dust around 1,300 light years from Earth and is located in the constellation of Orion.

The Nebula is actually part of a much larger nebula known as the Orion Molecular Cloud Complex.

The first recorded observation of the Orion Nebula doesn't appear until 1610, and this was thanks to the telescope which had been invented two years earlier.

Using his telescope the French astronomer Peiresc noticed the diffuse nebula and noted down his observations, he is therefore credited with its discovery.

Throughout the 17th century many others independently discovered the Orion Nebula including the famous Dutch astronomer Christiaan Huygens. In 1774 the French astronomer Charles Messier included the Orion Nebula in his now famous catalogue of deep space objects, naming it Messier 42 or M42, a tag is still widely used today by professional and amateur astronomers.

Orion Meteor Strike, The Winchcombe meteor seen over Gloucestershire by Raymond Majrowski

83 43

A WOW moment, I saw this huge fireball whiz through Orion as I was imaging the Orion Nebula, I quickly looked at the camera to see if it had caught the meteor, it had during a 30 second exposure. Made my day after a poor winters viewing. Due to the very few clear nights this winter, I decided to image the Orion nebula even though the full moon was present, it was probably my last chance to image the nebula before it sank too low toward the horizon by 9.00pm. A good decision to set up early, could easily have not bothered due to the moon making the sky too bright for imaging.

Single 30 second exposure @ ISO800, no filters were used.

The meteor, probably part of an Asteroid may well have originated from the asteroid belt around between Mars and Jupiter, exploded in the sky above Cheltenham UK. It was bright enough to be recorded by door bell video cameras. There are about 13 individual streaks the various colors might provide a spectroscopic analysis of the meteors composition, the lowest streak brightens and expands at one point.

Orion, by John White

My favorite constellation is Orion.

I like it first and foremost

because on a cold clear winter night

it is easy to find in the sky.

On a very special night,

far from the cities and stress

you can actually see the Great Orion Nebula

a cloud of interstellar gases where stars are actually born.

With each thought we share,

each story, picture and sound,

we see a little more of each other.

I'm certain if we keep looking,

on a very special night,

far from our daily lives,

we will discover the universe together.

The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae and is visible to the naked eye in the night sky with apparent magnitude 4.0. It is about 1,344 light-years away and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light-years across (so its apparent size from Earth is approximately 1 degree). It has a mass of about 2,000 times that of the Sun. (ref.

The Great Orion Nebula by Terry Robison

The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula, south of Orion's Belt in the constellation of Orion.

I remember having the opportunity to view Orion through a large telescope many years ago. It was indeed a WOW moment. What struck me was that I could see colour through the eyepiece. The many shades of green were easy seen, but it was the hues of reds and pinks were most impressive. I had never seen red nebulosity through an eyepiece before this experience, and this incredible experience was etched into my mind.

I wanted to capture that vision I had in my head and attempt to recreate an image of that experience. Orion is an incredibly high dynamic range object. It is very bright at its core, includes many dynamic caverns of roiling dust and gas throughout, with beautiful subtle dim wisps of gas everywhere in this complex structure.

This is my first attempt to create an image of Orion. It has its challenges as is quite a complex structure to process to reveal the range of feature within. My highlights would have to be the very subtle wisps of gases, shockwaves, and huge caverns of gas that create this dramatic image.

M42, the Great Orion Nebula by xylophilist

It's perhaps the most obvious deep-sky object to photograph, so it was high time I had a go. With a meeting looming last Friday evening, I set up the StarAdventurer tracker in the back garden and Sony camera firing 30s subs every 2mins. By the time I returned, the clouds had rolled in but I got 55mins of light data to be working on.

The Great Orion Nebula (Messier 42) Featuring Gooey-Delicious Dust and Gas by James Peirce

227 18

The Great Orion Nebula (Messier 42). We all know it. It’s one of the first targets we point our telescope or camera at before stumbling down the ridiculous rabbit hole that is astrophotography.

One of my main goals in astsophtoogrpahy has been to meticulously create the most detailed and deep image of the Orion Nebula I could manage. A perfect challenging in astrophotography, in my opinion, as Orion is both a delightful and easy target for beginners, and as advanced a target as we might like for revisiting in years to come. Over the past three years or so I’ve accumulated some 150 hours of data on Orion, scattered amidst assorted experiments and attempts in editing (which, up until now, I’ve never finished). Over the past four months I’ve collected the images for this rendition, and spent an embarrassing amount of time learning and experimenting with new (to me) post-processing approaches to arrive at this result. I’m sincerely delighted to share this labor of love with everyone.

Constrictive feedback and discussion are absolutely welcome.

Post-Processing

Source data includes two nights of long and short exposures captured with my Celestron RASA-8 and ZWO ASI2600MC Pro, and numerous nights captured with my Takahashi FSQ-106EDX4 and ZWO ASI2600MM Pro with Astronomik UV/IR L2 and Deep Sky RGB filters. With the Takahashi I captured short and long exposures in luminance and color, along with a separate 4-panel mosaic in LRGB (binned color) which I used for stars and fine detail in highlights. I discarded sub-par data from sessions liberally. A master luminance image was created with data combined from both telescopes (blended into RASA data for the larger field of view, which was a point of challenge). A master color image was created with the RASA data, which contributed color for nebulae and background. And the four-panel mosaic was prepared and processed separately, ultimately contributing detail in highlights and the stars in the final rendition. And just because, why not—I’ve gone this far—I used my best subset of 5s exposures captured in Hα, last year, for luminance on the Trapezium. (The original is more than 16000 pixels across, and I went out of my way to present fine detail so a large print could end up on my wall, allowing me to appreciate details up close, returning me to these fun and stupidly cold nights whenever I like.) Starless versions were sent out to Adobe Photoshop for final combination and blending. Some normal PixInsight steps, like HDR combination, also ended up being handled, in part, in Adobe Photoshop. PixInsight was used during this process for features such as Local Histogram Equalization.

It’s challenging to outline post-processing details on this one because the workflow ended up looking like the stereotypical insane person’s wall cataloging a crime scene investigation, but I’m delighted to answer any questions someone may have.

M42 is a glorious mix of diffuse nebula and one of the the brightest nebulae in the sky. It's a wonderful target for novice to experienced imagers as there's always more data and detail to find. It's easy to capture - but difficult to master. This is my 5th go at imaging M42, it feels like l I'm coming full circle as this was the target that inspired me to purchase by current Officina Stellare APO.

Previous attempts:

www.flickr.com/photos/astro-tanja/8103642749/ (comparisons since my 1st ever imaging of the target)

The choice of 2 exposure settings was to capture more feint outer detail with the longer exposure, and shorter exposures to maintain the inner core. After calibration the 2 masters were integrated using the HDRcomposition function in PixInsight. It's an easy method, making me wish I shot even more data for longer subs to get more detail in the surrounding feint nebulosity.

This target was imaged from the Johannesburg light polluted suburbs, with no light pollution filter. I spent 2 nights on this to acquire more data so that I can keep ISO lower.

Excited to see if next season will bring more improvements.

Messier 42 - First time in two years by Steven Rosenow

318 22

Ah yes. YES! <3

It felt so great to be one with my telescope again last night. After nearly four months, I was able to get the observatory open again and throw down with the photons.

This was one of my most fantastic captures I've done in ages. Last winter, I was completely unable to photograph this deep sky object due to persistent clouds and rain that seemed virtually relentless from November to March (which is incidentally prime season for this one).

Last night here at the observatory, we were blessed with a moment of rare, clear skies with transparency in the 80% range, so I wasted no time in getting things aligned and calibrated.

I present, for the first time in two years - Messier 42 - also known as the Great Nebula in Orion.

A total of 45 minutes' total exposure using ISO1600 and ISO3200 exposure frames. Few darks were used in the final calibration due to temps being in the low twenties. It was so cold in fact, that the metal ALT-AZ and DEC adjustment knobs on my telescope's mount kept freezing!.

Yes indeed, being back in the saddle again felt so great.

Captured using a Meade DS2120 OTA piggybacked to a 10-inch Meade LX200 Classic. The camera used to capture this was a Nikon D5500. EXIF file data unavailable due to stacking and calibration.

Messier 42 and 43 (remote, NM) by john.purvis

302 21

The Great Orion Nebula, number 42 in the Messier catalogue - this is centred on nearby M43, deQuervain's nebula - the bright pink circle.

Four young, massive and intensely luminous O class stars (in the bright white zone) pump out enough UV and soft X-ray light to illuminate this whole region of space and make hydrogen clouds fluoresce pink at 656.4nm.

Those stars will burn rapidly through their hydrogen fuel and then probably go supernova in just a few million years - burn bright and die young!

Cold gas forms dark clouds, folds and shadows. New stars will form where the cold gas collapses under gravity.

Running Man And Orion by Zircon_215

The Running Man Nebula or NGC 1977 is a reflection nebula that is found in the Orion constellation ... almost 1500 lightyears away. It is called the Running Man because the shape looks exactly like that ... ie a man running. It is to the left in this photo ... a purple shape on a field of blue. But in the night sky the Running Man is actually above Orion, but here in this photo I rotated it so that you could see it better.

The Orion Nebula (Messier 42 or NGC 1976) on the right here in this photo is a diffuse nebula just south of Orion's Belt in the constellation of Orion. It is a bright nebulae and is visible to the naked eye in the night sky ... but only as a faint fuzzy smudge unless you have the help of a telescope.

This image is composed of only 11 images stacked and processed in PixInsight and Photoshop. With more images there would be much more detail visible.

The Great Nebula in Orion (M42) by Davide Simonetti

A quick shot of the Orion Nebula (M42), one of my favourite celestial objects and a really satisfying target. I've been waiting a year for an opportunity to image this nebula again, this time with a polar alignment and guiding to enable much longer exposures than the 15 second subs I took last time and with a lower ISO to reduce noise. The next project with this is to either stitch two shots together or, better still, rotate the camera in order to fit both the Orion Nebula and the nearby Running Man Nebula into one frame.

It has a mass of about 2000 times the mass of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula.

The Orion Nebula is one of the most scrutinized and photographed objects in the night sky, and is among the most intensely studied celestial features. The nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. Astronomers have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the nebula. [Wikipedia]

An international team of scientists have used data collected by the NASA/ESA/CSA James Webb Space Telescope to detect a molecule known as the methyl cation (CH3+) for the first time, located in the protoplanetary disc surrounding a young star. They accomplished this feat with a cross-disciplinary expert analysis, including key input from laboratory spectroscopists. The vital role of CH3+ in interstellar carbon chemistry has been predicted since the 1970s, but Webb’s unique capabilities have finally made observing it possible — in a region of space where planets capable of accommodating life could eventually form.

This image is NIRCam’s view of the Orion Bar region studied by the team of astronomers. Bathed in harsh ultraviolet light from the stars of the Trapezium Cluster, it is an area of intense activity, with star formation and active astrochemistry. This made it a perfect place to study the exact impact that ultraviolet radiation has on the molecular makeup of the discs of gas and dust that surround new stars. The radiation erodes the nebula’s gas and dust in a process known as photoevaporation; this creates the rich tapestry of cavities and filaments that fill the view. The radiation also ionises the molecules, causing them to emit light — not only does this create a beautiful vista, it also allows astronomers to study the molecules using the spectrum of their emitted light obtained with Webb’s MIRI and NIRSpec instruments.

The two very large, bright stars are two of the three stars in the θ² Orionis system — the Trapezium Cluster is also known as θ¹ Orionis. The brightest star here, θ² Orionis A, is surrounded by particularly bright and red puffs of dust, which are reflecting the star’s light towards Earth. Its great brightness — it is visible with the naked eye — is due to the fact that θ² Orionis A is itself a ternary system made of three closely bound bright stars.

There are more proplyds visible in this image than just d203-506 — the Orion Nebula is replete with such new stars. In the very top left, a tiny star is visible within a long, dusty cocoon. This globule has formed from the star’s protoplanetary disc, as the disc is broken down by the energetic radiation of the Trapezium Cluster. Around the globule, a round shockwave is strikingly visible moving through the gas of the Orion Nebula.

[Image description: A nebula made of many layers of cloudy, colourful material. The top-left side of the image is brightly lit, filled with wispy, thin material in pale shades of pink and blue. A thick bar of denser, cloudier material crosses diagonally at the bottom right. It begins as orange and grows darker and sparser down to the corner. Two very bright stars, with very long diffraction spikes, lie in this sparse area.]
