M42 & NGC1977 shot with my telephoto lens @ 230mm, F5.6, from my balcony. Bortle class 7-8 area.

Before you draw your conclusions about this image, please read the description.

The sky and foreground were captured back to back at the same focal length and with the same equipment from a single tripod position.

The camera position was roughly 2 miles away from the mountain station, and the telescope/camera combination has an extremely narrow field of view of only 1.5° x 2°. The resulting telephoto compression makes the otherwise tiny Orion Nebula appear huge.

Two years ago, I had already captured a similar deepscape, but I was never really satisfied with it. The problem was lacking data for my sky, especially in the green channel, as clouds moved in towards the end of the imaging session.

Of course, I could have recaptured the missing data or the entire Orion Nebula from a different place, but that's not my style. After waiting two years for an opportunity to reshoot the image, I finally got my chance this February.

The weather this time was perfect, which made capturing the sky pretty straightforward, but otherwise, the conditions were still as demanding as 2 years ago.

Getting the foreground in focus with a monochrome micro 4/3rd astro-cam and RGB filters through a 500mm f/5.6 telescope is a real pain. Furthermore, snowcats grooming the slopes caused constantly changing, extremely bright illumination. Considering this, I am quite happy that I was able to capture a usable foreground.

Explanation: A bright spiral galaxy of the northern sky, Messier 63 is about 25 million light-years distant in the loyal constellation Canes Venatici. Also cataloged as NGC 5055, the majestic island universe is nearly 100,000 light-years across, about the size of our own Milky Way. Known by the popular moniker, The Sunflower Galaxy, M63 sports a bright yellowish core and sweeping blue spiral arms, streaked with cosmic dust lanes and dotted with pink star forming regions. This deep exposure also reveals an enormous but dim arc extending far into the halo above the brighter galactic plane. A collaboration of professional and amateur astronomers has shown the arc to be consistent with the stellar stream from a smaller satellite galaxy, tidally disrupted as it merged with M63 during the last 5 billion years. Their discovery is part of an increasing body of evidence that the growth of large spirals by cannibalizing smaller galaxies is commonplace in the nearby Universe.

My mount was polar aligned with SharpCap (what an amazing system for aligning). I then mounted my a7RIII and adapted Nikon 500mm f/4 P Ai-s lens to the top rail of my scope. I used SharpCap to achieve "excellent" polar alignment. I shot ISO 3200, f/5.6 and 75" exposures. I stacked lights/darks/flats/bias frames in deepskystacker. I then processed the TIFF file in photoshop stretching the file, cropping and I used Astronomy Tools Action Set to help bring out details and colors along with Topaz Denoise to help smooth things out.

I have been waiting and waiting since November to have a clear night with no wind or moonlight on a weekend. Finally, I got my chance in late March, and it was my last shot until next November as Orion will start to fade below the horizon in April.

Orion is one of my favorite deep space objects to photograph, but the bright core makes it a challenge to capture well. I really like how this turned out!

M78 is is the blue reflection nebula in the centre of the frame and Barnards loop is the red / pink area to the left of the frame.

The nebula Messier 78 (also known as M78 or NGC 2068) is a reflection nebula in the constellation Orion. It was discovered by Pierre Méchain in 1780.

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.

Barnard's Loop (Sh2-276) is an emission nebula in the constellation of Orion.The loop takes the form of a large arc centered approximately on the Orion Nebula. The stars within the Orion Nebula are believed to be responsible for ionizing the loop. Recent estimates place it at a distance of between 518 light years and 1434 light years giving it dimensions of either about 100 or 300 light years across respectively. It is thought to have originated in a supernova explosion about 2 million years ago, which may have also created several known runaway stars.

This is another image taken with the dual rig.

The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus, at about 2400 light years from us.

It constitutes the visible portions of the Cygnus Loop,a supernova remnant, many portions of which have acquired their own individual names and catalogue identifiers. In modern usage, the names Veil Nebula, Cirrus Nebula, and Filamentary Nebula generally refer to all the visible structure of the remnant, or even to the entire loop itself. The structure is so large that several NGC numbers were assigned to various arcs of the nebula. There are three main visual components: 1. The Western Veil (also known as Caldwell 34), consisting of NGC 6960 (the "Witch's Broom", Lacework Nebula, "Filamentary Nebula"; 2. The Eastern Veil (also known as Caldwell 33), whose brightest area is NGC 6992, trailing off farther south into NGC 6995 (together with NGC 6992 also known as "Network Nebula"; 3. Pickering's Triangle (or Pickering's Triangular Wisp), brightest at the north central edge of the loop, but visible in photographs continuing toward the central area of the loop.

The source supernova was a star 20 times more massive than the Sun which exploded between 10,000 and 20,000 years ago. At the time of the explosion, the supernova would have appeared brighter than Venus in the sky, and visible in the daytime. The remnants have since expanded to cover an area of the sky roughly 36 times the area of the full Moon.

NGC 4038 and NGC 4039 are known as the Antennae, or sometimes called the "rat-tail" galaxies. They are located near the western edge of Corvus.

This pair of interacting galaxies was discovered by William Herschel in 1785. The Antennae Galaxies are the nearest and youngest example of a pair of colliding galaxies. About 1.2 billion years ago, the Antennae were two separate galaxies. Simulations of colliding galaxies suggest that the two will eventually form a single elliptical galaxy.

This deep-space image showcases two stunning nebulae in the constellation Auriga: the Tadpoles Nebula (IC 410) at the top center, and the Flaming Star Nebula (IC 405) toward the lower left.

IC 410, the Tadpoles Nebula, is an emission nebula located about 12,000 light-years from Earth. It surrounds the young star cluster NGC 1893, whose massive, energetic stars light up and shape the surrounding gas. The 'tadpoles' that give the nebula its nickname are dense streams of dust and gas about 10 lightyears long. They are assumed to be sites of star formation.

IC 405, the Flaming Star Nebula, lies in the lower left portion of the image. This beautiful mix of emission and reflection nebula is about 1,500 light-years away and is illuminated by the hot, massive star AE Aurigae. Its flowing, flame-like filaments of gas and dust give the nebula its name and striking appearance.

Set against a dense star field, this image uses narrowband imaging techniques to highlight different elements: hydrogen, oxygen, and sulfur. The result reveals both the structure and composition of these rich star-forming regions.

Peek toward the handle of the Big Dipper with a telescope and you can find the Pinwheel Galaxy also known as M101. It lies 21 million light-years away, meaning the light traveled for 21 million years before hitting my camera's sensor. Discovered in 1781 by Pierre Méchain, one of Charles Messier's colleagues, the spiral arms stretches 170,000 light-years wide—almost twice the size of our Milky Way Galaxy.

I brought the lights/darks/flats/bias frames into PixInsight for stacking and aligning and then used: STF, Cropping, GraXpert, Dynamic Background Extraction, BlurXTerminator, plate solving, color correction, NoiseXTerminator, and then the galaxy was separated from the stars using StarXterminator, and both files processed and stretched separately and then recombined using PixelMath. That file was brought into Lightroom for Metadata and EXIF tags, light post-processing, and cropping. I used Photoshop to sharpen the final image.

My Friday night was spent setting up my scope and targeting the Andromeda Galaxy. It is the furthest object visible to the naked eye as it lies relatively close to us at only ~2.5 million light years from Earth.

DeepSkyStacker was used to combine all frames, and then I processed the TIFF file in Photoshop. I stretched the 32-bit file using Levels. I then made it a 16-bit file and continued to stretch the file in levels and curves. I used the color sampler tool and levels to do my best to help keep colors accurate. I then used my skillset, including some dodging & burning, and relied on Astronomy Tools Action Set and Topaz Denoise to give the image a polished look. I brought it into Lightroom to do final color corrections and add EXIF data.

Messier 104 a.k.a. Sombrero Galaxy

…………………………..

Discovered 250 years ago, the Sombrero galaxy (The Hat) is an elliptical galaxy located just over 30 million light-years from us and can be seen between the constellation Virgo and the constellation Corvus. According to measurements made by specialists in the field, M104 has a diameter of about 40,000 light-years, being about 3 times smaller than our galaxy. The name of the Hat is given both by the angle from which we can see it, and due to that prominent ring of cosmic dust that surrounds this galaxy and which is also the main source of new star formation. Regarding the nucleus of this galaxy, with the help of special infrared measurements it was found that in the galactic center of M104 there is a massive black hole, larger than in any other galaxy located within a radius of 40 million light years around the Milky Way.

M1 - An Explosion in Space

Sky-watchers on Earth witnessed and wrote about a bright “supernova” (literally meaning “new star”) in the year 1054. What they were really viewing was the birth of rapidly expanding clouds from an exploding star. By the year 2021, roughly one thousand years later, these clouds have covered a distance of nearly 10 light years, and they continue to expand at a rate of about 1000 kilometers per second.

In 1840, after viewing this supernova remnant through a telescope and sketching it, astronomer William Parsons thought that it looked like a crab, and the name “Crab Nebula” caught on. If you can't see such a crab, you're not alone! With modern cameras we can collect so much more light and detail than that which could be previously captured with the eye and eyepiece combo, so to me (and probably to you) it looks more like, well, an explosion in space.

IC5070 (the Pelican nebula) is located in the constellation of Cygnus at approximately 1800 light years from Earth. You can see on the right of the image a large pillar of gas and at the tip of this is a Herbig-Haro object.

Herbig-Haro 555 is a narrow jet of gas and matter, ejected by newly born stars at speeds of several hundred kilometres per second. It collides with nearby gas and dust in the interstellar medium, producing bright shock fronts that glow as the gas is heated by friction while the surrounding gas is excited by the high-energy radiation of nearby hot stars.

Discovered in 2011 by French astrophotographer Nicolas Outters, the Squid Nebula (Ou4) is distinguished by its elegant bipolar shape and the vivid blue glow of doubly ionized oxygen (Oiii). It is nestled entirely within the reddish hydrogen-rich emission nebula Sh2-129, also known as the Flying Bat Nebula.

Recent research indicates that Ou4 lies roughly 2,300 light-years from Earth and resides within Sh2-129. This makes Ou4 a dramatic outflow, originating from HR 8119, a triple system of hot, massive stars at the nebula’s core. With an enormous physical size of nearly 50 light-years, the Squid Nebula stands as one of the largest and most intriguing emission structures in the night sky.

Capturing the Squid Nebula is a real challenge and requires very long integration times over several nights... The perfect challenge to test my new deep space imaging rig.

Messier 56 is a globular cluster of stars in the constellation of Lyra. It was discovered in 1779 by Charles Messier.

Spanning 84 light-years in diameter and approx 32,900 light years away it is believed to be about 13.7 billion years old, It is believed to contain around 80,000 stars.

​

A globular cluster is a spherical collection of stars that orbits a galactic core as as satellite. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes and relatively high stellar densities toward their centres.

Discovered in 1786 by William Herschel, the North

America Nebula shows its characteristic shape only in wide field astrophotographs.

The North America Nebula is separated from the Pelican Nebula by a dark dust cloud catalogued in 1962 as L935.

It took until 2004 for astronomers to identify the star that ionizes both the North America and the Pelican Nebula. The light of the inconspicuous star, named J205551.3+435225, is almost entirely blocked by the dark cloud L935. As J205551.3+435225 lies just off the “Florida coast” of the North America Nebula, it has been more conveniently nicknamed the Bajamar Star ("Islas de Bajamar," meaning "low-tide islands" in Spanish, was the original name of the Bahamas).

This object bears a striking resemblance to the much closer NGC 1535 which I posted a few weeks ago.

The Eastern Veil nebula is a cloud of heated and ionized gas and dust in the constellation of Cygnus, located at around 1470 light-years from Earth. It is part of the Cygnus Loop which is a 7000 years old, faint supernova remnant, covering roughly 3° on the sky (almost 6 full moons). The red hues in this image are from ionized hydrogen gas clouds, emitting light in the H-alpha wavelength, while the cyan hues are from oxygen ions.

M 3 is found in the constellation Canes Venatici and is one of the three brightest globular clusters in the northern sky.

Discovered by Charles Messier in 1764 and later by William Herschel in 1784.

I chose this cluster because when the moon is bright (99%), you need a bright image to be able see through the Moon glow in the sky. We have been having really poor weather in southern Spain and this was a small opportunity to take an image in between the clouds. Unfortunately the humidity was at 100% for the entire session making for slightly blurred stars, but I though it would be a challenge to see what I could make of just 2.5 hours of data under extreme conditions.

A single night of imaging in June 2023 from my home in Gérgal, Spain.

This is a 4 night Two panel shot join is in the middle of the two shots. As I am able to rotate the Nikon 300mm F4 prime on its lens clamp I marked the degrees so I could rotate to suit camera angle. once done I got an error reading each night 1.4 degrees.

the two panels joined perfectly with next to no step between the two panels. I am impressed so much I am almost willing to for go the Auto Focus with the belt to be able to rotate the camera.

The Dumbbell Nebula (also known as the Apple Core Nebula, M 27, and NGC 6853) is a planetary nebula (nebulosity surrounding a white dwarf) in the constellation Vulpecula, at a distance of about 1360 light-years. A planetary nebula is a type of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from red giant stars late in their lives. [wikipedia]

Located about 5000 light years from Earth, the center image shows the Rosette star formation region. The stars of NGC 2244 formed from the surrounding gas only a few million years ago. A survey of the nebula with the Chandra X-ray Observatory has revealed the presence of numerous new-born stars inside optical Rosette Nebula and studded within a dense molecular cloud. Altogether, approximately 2500 young stars lie in this star-forming complex, including the massive O-type stars HD 46223 and HD 46150, which are primarily responsible for blowing the ionized bubble. Most of the ongoing star-formation activity is occurring in the dense molecular cloud to the south east of the bubble.

This is a part of my new project currently under construction: Part One and two of ten panels. (this image is made up of two panels) This will eventual form a skyscape including Caldwell 49 up to and including the Cone Nebula and Christmas Tree Cluster.

NGC 6960 a.k.a. Western Veil Nebula a.k.a. The Witch's Broom

………………………………………

10,000 years ago, long before the first records in human history, a bright light appeared in the sky and lasted for weeks until it faded and disappeared. Now we know that the phenomenon was caused by the explosion of a supernova, a huge star, 20 times larger than the Sun. What is seen in the attached image is a part of the remnants of that star, remnants that created a cloud consisting mainly of hydrogen (red) and oxygen (blue) and which expands with a speed of about 1 milion miles per hour.

This nebula is found in the constellation Cygnus, at a distance of about 2400 light-years from Earth, and is one of the best known summer targets for astrophotography enthusiasts, but due to the large number of stars in that area, it cannot be considered a easy target.

Besides Witch's Broom, other names under which this nebula is known are: Finger of God, Filamentary Nebula or Lacework Nebula.
