On December 19th 2020, I was outside in southern Brandenburg (Germany) to watch the night sky and take photos of the Orion region. Unfortunately I had to throw away 1/3 of the pictures because the Astrotrac had some tracking problems due to frost and high humidity.

Full frame image starting with dark nebula LDN 1622 (Boogeyman Nebula) at top left through the glowing red hydrogen alpha of Barnard's Loop which is thought to be the shock wave of a previous supernova explosion down to the complex Messier 78 with dark nebula components and bluish reflection nebulae where young, bright stars light the surrounding dust which scatters blue preferentially.
The constellation Orion is riddled with gas and dust, which is especially visible in longer exposed photos. This photo was taken on January 6, 2022 only 5 kilometers from the city center of my hometown Lübben (Spreewald).

38 x 3 minute sub-exposures taken with the iTelescope T68, 28cm aperture, f/2.2 scope in Australia.
This is part of the huge Orion molecular cloud of dust and gas which acts as a stellar nursery.
In the centre of the image, two young B-class stars (HD 38563A and HD 38563B) are reflected in the surrounding gas with an overlying dark arch.
Towards the left is another reflection nebula, NGC 2071.
NGC 2064 and NGC 2067 are the two bright zones above the dark arch.
Towards the lower right, some early stars are just managing to penetrate the darkness as red or yellow splotches. One of these splotches (triangular - just to right of two small stars) brightened considerably in 2004 - its thought a young star ignited at that time - the region is called McNeil's nebula after the amateur who first noticed it.
Top left has a deep red colour as the field of view starts to include hot emitting hydrogen atoms in supernova remnant Barnards loop.
There is another reflection nebula at top left but so far I can't find a reference number for it.
Infra-red imaging shows about 45 new stars in the early phases of development in this cloud (T-tauri stars or Herbig-Haro objects which are outflow jets from young forming stars).

This is a rescued image from February 2022. I was still finding my way with CMOS imaging back then and I think I badly underexposed the subexposures here.
PixInsight didn’t give me anything useable but I ran the 90 x 3 minute subs through ASI deep stack tonight and came out with something.
My most successful run at this target was taken remotely with a very fast scope in Colorado here:
Certainly the background stars are a great colour and not over-exposed but I’m not sure if 3 minutes exposure (gain 100, offset 50) is the right option for a f/6-7 system - it's commonly mentioned on imaging fora but people tend not to specify their f-stop!
Update - I'm using 5 minutes, Gain 100, Offset 25 as a standard now.
This is an update on a previously acquired image - previously 16 x 5 minute exposures. A further 24 x 6 minute exposures have been added.
This is part of the huge Orion molecular cloud of dust and gas which acts as a stellar nursery.
In the centre of the image, two young B-class stars (HD 38563A and HD 38563B) are reflected in the surrounding gas with an overlying dark arch.
Towards upper left is another reflection nebula, NGC 2071.

Messier 78, or NGC 2068 is a very photogenic group of nebula in Orion, closely grouped with NGC 2064, NGC 2067 and NGC 2071.
Discovered by Pierre Méchain in 1780, the nebula is 1,360 light years away and often overlooked in favour of it's more famous nearby neighbours, the Great Orion Nebula and the Horsehead nebula.
With the recent announcement that La Nina is visiting this summer, the plan to add more exposure to this image became questionable, so I decided to process what I had.
This is only 4 hours exposure, 1 hour each of L,R,G,B.

Messier 78
This new image of the reflection nebula Messier 78 was captured using the Wide Field Imager camera on the MPG/ESO 2.2-metre telescope at the La Silla Observatory, Chile. This colour picture was created from many monochrome exposures taken through blue, yellow/green and red filters, supplemented by exposures through a filter that isolates light from glowing hydrogen gas. The total exposure times were 9, 9, 17.5 and 15.5 minutes per filter, respectively.

M78 is the brightest diffuse reflection in the night sky and looks great when photographed with a telescope, but can also be captured wide-field using a camera and lens.
This picture was taken under Bortle 2 skies using the RASA f/2, ASI2600MC and no filters. 27 hours total.
I'm a bit obsessed with revealing all the dust in images right now so I might reprocess this later without caring too much about the dust as it definitely does overwhelm the image overall.

Took me several attempts to get this 3-tile mosaic working, and here is the result. Because of Christchurch's light halo close to Orion at the shooting location, I had a significant gradient across all 3 tiles which caused me troubles. Then tiny black bands screwed up with registration, and finally the usual mix of high noise floor, lack of images due to short summer nights, etc ...
But anyway it was a good exercise to prepare for a mosaic, preprocess it for RGB and Ha images, and I guess it could look worse. I can always tidy up little things here and there, but doubt I would get too much more out of the shots with my current knowledge of PixInsight. ;-)
3-tile mosaic at 120mm focal length, each is a combination of 5 x 120s @ 1600ISO in RGB and 5 x 240s @ 4000ISO through IR645 filter, all at F6.3.

M78 is a blue reflection nebula located in a dusty area of the Orion arm of our galaxy. Note how the dust lanes hide the stars located in the background. To image this, I had to struggle with a huge light pollution from the town of Aix. It affected the colour balance and I had to accumulate a lot of data.

The Messier Catalog, sometimes known as the Messier Album or list of Messier objects, is one of the most useful tools in the astronomy hobby. In the middle of the 18th century, the return of Halley's comet helped to prove the Newtonian theory, and helped to spark a new interest in astronomy. During this time, a French astronomer named Charles Messier began a life-long search for comets. He would eventually discover 15 of them. On August 28, 1758, while searching for comets, Messier found a small cloudy object in the constellation Taurus. He began keeping a journal of these nebulous (cloudy) objects so that they would not be confused with comets. This journal is known today as the Messier Catalog, or Messier Album. The deep sky objects in this catalog are commonly referred to as Messier objects.
The New General Catalogue of Nebulae and Clusters of Stars (abbreviated as NGC) is a catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888 as a new version of John Herschel's General Catalogue of Nebulae and Clusters of Stars. The NGC contains 7,840 objects, known as the NGC objects. It is one of the largest comprehensive catalogues, as it includes all types of deep space objects and is not confined to, for example, galaxies. Dreyer also published two supplements to the NGC in 1895 and 1908, known as the Index Catalogues, describing a further 5,386 astronomical objects.
Looking like a pair of eyeglasses only a rock star would wear, this nebula brings into focus a murky region of star formation. NASA's Spitzer Space Telescope exposes the depths of this dusty nebula with its infrared vision, showing stellar infants that are lost behind dark clouds when viewed in visible light.
Best known as Messier 78, the two round greenish nebulae are actually cavities carved out of the surrounding dark dust clouds. The extended dust is mostly dark, even to Spitzer's view, but the edges show up in mid-wavelength infrared light as glowing red frames surrounding the bright interiors. Messier 78 is easily seen in small telescopes to the naked eye in the constellation of Orion, just to the northeast of Orion's belt, but looks strikingly different, with dominant, dark swaths of dust. Spitzer's infrared eyes penetrate this dust, revealing the glowing interior of the nebulae.
The light from young, newborn stars are starting to carve out cavities within the dust, and eventually, this will become a larger nebula like the "green ring" imaged by Spitzer
A string of baby stars that have yet to burn their way through their natal shells can be seen as red pinpoints on the outside of the nebula. Eventually these will blossom into their own glowing balls, turning this two-eyed eyeglass into a many-eyed monster of a nebula.
This is a three-color composite that shows infrared observations from two Spitzer instruments. Blue represents 3.6- and 4.5-micron light and green shows light of 5.8 and 8 microns, both captured by Spitzer's infrared array camera. Red is 24-micron light detected by Spitzer's multiband imaging photometer.

The nebula Messier 78 (also known as M 78 or NGC 2068) is a reflection nebula in the constellation Orion. It was discovered by Pierre Méchain in 1780 and included by Charles Messier in his catalog of comet-like objects that same year.
M78 is the brightest diffuse reflection nebula of a group of nebulae that include NGC 2064, NGC 2067 and NGC 2071. This group belongs to the Orion Molecular Cloud Complex and is about 1,600 light years distant from Earth. M78 is easily found in small telescopes as a hazy patch and involves two stars of 10th magnitude. These two stars, HD 38563A and HD 38563B, are responsible for making the cloud of dust in M78 visible by reflecting their light.
About 45 variable stars of the T Tauri type, young stars still in the process of formation as well as some 17 Herbig-Haro objects are known in M78.
Captured with a Nikon D5500 and a 10-inch Meade LX200 'Classic' f/6.3 wide-field telescope.

This is the reflection nebula Messier 78 in the constellation Orion. Obviously the neither the telescope nor the exposure I chose where sufficient for this object. But I was in a hurry because Superbowl 52 was about to start. Shot with an EOS 550D mounted to a Meade ETX 70 telescope. Exposure was around 8 minutes and 24 seconds with ISO 800.
Stunning new view from ESAs Herschel space observatory of the iconic Horsehead Nebula in the context of its surroundings. The image is a composite of the wavelengths of 70 microns (blue), 160 microns (green) and 250 microns (red), and covers 4.5x1.5 degrees. The image is oriented with northeast towards the left of the image and southwest towards the right.
The Horsehead Nebula resides in the constellation Orion, about 1300 light-years away, and is part of the vast Orion Molecular Cloud complex. The Horsehead appears to rise above the surrounding gas and dust in the far right-hand side of this scene, and points towards the bright Flame Nebula. Intense radiation streaming away from newborn stars heats up the surrounding dust and gas, making it shine brightly to Herschels infrared-sensitive eyes (shown in pink and white in this image).
To the left, the panoramic view also covers two other prominent sites where massive stars are forming, NGC 2068 and NGC 2071.
Extensive networks of cool gas and dust weave throughout the scene in the form of red and yellow filaments, some of which may host newly forming low-mass stars.
