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.

Planetary Nebula in Orion
A dying star.

==================================
This object bears a striking resemblance to the much closer NGC 1535 which I posted a few weeks ago.
The cluster and nebula lie at a distance of 5,000 light-years from Earth and measure roughly 130 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see.

The Rosette Nebula is relatively easy to find, it is located about a third of the way between the star Betelgeuse in Orion and the star Procyon in Canis Minor.

In honor of tonight's full moon, here's an image from last month's full moon which I photographed about an hour after it rose.
The moon itself here is my capture, and I have used a deep space filter layered behind it, giving a three dimensional element and experience.

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]

Red hydrogen emission and blue reflection nebulae, dark molecular clouds and a bright star sitting in the middle, flooding the scene its yellow light... Sounds like the Rho Ophichui region?
Sure. There is, however, another smaller, but similarly colorful area in the sky:
Meet the Cave Nebula!
Officially designated Sh2-155, the Cave Nebula in the constellation Cepheus, is a diffuse nebula of ionized hydrogen with ongoing star formation activity, at an estimated distance of 2400 light-years from Earth. It lies within a larger complex containing emission, reflection, and dark nebulosity.
The name "Cave Nebula" for Sh2-155 was coined by Patrick Moore, presumably derived from photographic images showing a curved arc of emission nebulosity corresponding to a cave mouth. Earlier, the name was already used to refer to another brighter but unrelated reflection nebula in Cepheus, known as Ced 201. The name's application to Sh2-155 has come into vogue through the nebula's inclusion in Moore's Caldwell catalogue as object Caldwell 9.

NGC 7635 a.k.a. Bubble Nebula
……………………………................
Space is full of things / situations / events that intrigue us, NGC7635 being one of those. In short and for everyone to understand, a massive star is caught in a "bubble". This star is almost 50 times larger than the Sun and the emitted radiation is about 1 million times stronger than it, producing a stellar wind that exceeds 5 million km per hour, wind that pushes dust and gas outward creating thus a shell or a bubble, a situation that obviously led to the popular name of this nebula.
As general information, the Bubble Nebula is an emission nebula with a diameter of about 7 light-years, located in the constellation Cassiopeia, at a distance of over 7000 light-years from Earth and it was discovered in 1787 by the British astronomer, William Herschel.
Specialists believe that in a short time ( meaning in the next 10-20 million years), the "guilty" star will consume its energy resources, and will explode, forming a supernova.

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.

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.

Mars reflects the sun's light and is ~22 light minutes from Earth. The Pleiades is an open star cluster that is ~ 442 light years away from us. While these two are so different, both of them are prominent and easy to spot in the night sky. It’s very cool to witness the two so close to each other. I knew this was happening, but my life and job have been so busy lately it slipped my mind until it was basically happening already.
Step outside tonight and take a lookup. You can find this event just ahead of the constellation Orion. The next time these two will be near each other in our night sky again in 2038!

My mount was polar aligned with SharpCap (what an amazing system for aligning). I'm not comfortable using my SCT as my lens yet. My solution is to piggyback my Sony a7RIII and adapted Canon FD 300mm f/4 L on a ADM dovetail rail on the top of my optical tube. I used DeepSkyStacker to combine all frames and then processed the TIFF file in Photoshop. I stretched the 32 bit file and used Gradient XT on the image. I then made it a 16 bit file and stretched in level, then curves. I used the color sampler tool and levels to do my best to keep the background space black. I then using my skillset and relied on Astronomy Tools Action Set, and dodging and burning a bit to give the image the finishing touches.

In-depth Description:
This is a dynamic looking region of the constellation Auriga where spherical nebulas appear hurled to crash into each other. This image includes the nebulae Sh2-232, Sh2-235, Sh2-231, Sh2-234 and LBN 796, among others, and the open star clusters M38 and M36.
The eyeball looking nebula (Sh2-232) has been mistaken for a planetary nebula, but none of the round or semispherical objects in this image are actually classified as PNs (per Galaxymap and SIMBAD). In fact, the big fuzzy ball in the lower left center (right above cluster M36) does not seem to have any designation at all and is merely a part of the greater nebula LBN 796. A 2012 study suggests that these unusual forms are all part of an expanding shell, the result of an ancient supernova.
These nebulae are all features of a larger molecular cloud located 1800 pc from us. By comparison the two clusters are much closer: M36 (bottom center) is 1330 pc distant, and M38 (center right) lies only 1066 pc away.

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.

Era doveroso, dopo 13 anni, ritornare su questa bellissima nostra "vicina di casa" extragalattica, la grande Galassia di Andromeda, catalogata con le sigle M31 e NGC224 distante dalla Terra circa 2,5 milioni di a.l.. Se i nostri occhi fossero molto sensibili e non ci fosse l'Inquinamento luminoso la vredremmo in tutta la sua grandezza: le sue dimensioni apparenti sono più di 6 volte quelli del disco lunare.
Con il mio setup ho dovuto realizzare un mosaico con 2 pannelli, ma dopo l'esperienza faticosa con la NGC7000, questa volta ho trovato il modo migliore per unire i 2 pannelli grazie all'applicazione Siril 1.4 che permette di unire più pannelli con opportuni accorgimenti, che rende il risultato finale più equilibrato nei punti di unione tra i pannelli (vd youtu.be/4apAdLWJ3Dg?si=gwMaWN7lphNVQitW).
Volevo integrare più ore in banda larga, utilizzando il filtro UHC, ma condizioni meteo avverse non lo hanno permesso con la galassia sempre meno alta sull'orizzonte e in una zona di cielo più inquinata.
Quindi mi sono concentrato sulle tantissime nebulose Ha presenti tra i bracci della galassia.

It was only right, after 13 years, to return to this beautiful extragalactic "neighbor" of ours, the large Andromeda Galaxy, catalogued with the acronyms M31 and NGC224, about 2.5 million light years away from Earth. If our eyes were very sensitive and there were no light pollution, we would see it in all its grandeur: its apparent dimensions are more than 6 times those of the lunar disk.
With my setup, I had to create a mosaic with two panels, but after the tiring experience with the NGC7000, this time I found the best way to join the two panels thanks to the Siril 1.4 application, which allows you to join multiple panels with appropriate adjustments, making the final result more balanced at the joins between the panels (see youtu.be/4apAdLWJ3Dg?si=gwMaWN7lphNVQitW).
I wanted to integrate more broadband hours, using the UHC filter, but adverse weather conditions prevented it, with the galaxy increasingly low on the horizon and in a more polluted area of the sky.
So I focused on the many Ha nebulae present in the galaxy's arms.

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).

The first color image to feature Sivan 5 and Sivan 6?
I believe this is the first successful color image of the nebulae Sivan 5 and Sivan 6. Siv 5 is the larger mass at the top. Siv 6 lies beneath it and includes Sh2-287, the bright section bottom center. The swooping red wisp that stretches from left to right and looks like a ship’s hull isn’t officially part of either nebula.
Astronomer J.P. Sivan identified these forgotten nebulae in 1974 from an Hα survey of the Milky Way in which they appeared as a couple of tiny, irregular blots. Apparently, no one has bothered with them since.
Sivan nebulae are large and exceedingly faint: this image spans over 5° of the constellation Monoceros; and total exposure time is 74 hours with narrowband filters. This area has been photographed before, but always with far less exposure time. Thus, they scarcely reveal these Sivan objects at all, not that anyone was looking for them. In fact, even the small, brighter Sharpless objects in this image barely appear in most other widefield images. If you find any that clearly show these Sivan nebulae, please let me know and I will update this page.
...Speaking of blots, in the cosmic Rorschach ink blot test that is interstellar space, to me this looks like a dog (or seal) sitting in a boat with a single sail. So, I call this the Seadog Nebula.

The skies were not really dark enough as our imaging location was only 1,5hrs drive out of town. I think to achieve more red in Antares' region I'll need to take separate Ha exposures and blend them to this.

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.

This galaxy has an inner bar rotating at a faster speed than the outer bars resulting in this shape. Our own galaxy could also be a barred spiral galaxy.

Another project I've been working on, this one is part of the Orion complex, including the Orion, Running Man, Horse head, and Flame nebulae. These things have been extremely fun to put together and as I said with the last one, I love the context it gives when compared to a terrestrial objects. This is all shot at 300mm. Foreground is obviously shot separately from the sky.

You are looking at a galaxy edge-on that is located 30 million light years away in the constellation Andromeda.
Consider our own Milky Way galaxy which is a huge disk of stars measuring 100,000 light years in diameter but only 1000 light years thick. So galaxies are quite thin relatively speaking.
A so-called edge-on view of a galaxy is like looking at the edge of a dinner plate and trying to see to the other side through the most dense portion. In the case of a galaxy this is mostly interstellar dust which is the dark linear region you see here. NGC 891, also referred to as the “silver sliver” galaxy, is very similar to our own Milky Way in size and luminosity.
The next time you see the Milky Way in a dark sky remember you are actually looking at it edge on also but this time you are on the inside looking out!

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.

My a7rIII and adapted Nikon 800mm f/5.6 lens were mounted to my SkyWatcher EQ6-R mount using a vixen rail. The guidescope/camera was fixed to the front of the rail. I used SharpCap to achieve "excellent" polar alignment. I shot ISO 1600 at f/5.6. I took 212-second exposures using PHD2 with my guidescope to keep tracking accurately. 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.
