So I'm quite pleased with the final result of the Western Veil Nebula. I've also done a mosaic of Pickering's Triangle and the Western Veil.
This represents about 10 hours of accumulated capture time for the mosaic.
nebulosa del Alma, también conocida como IC 1848, una vasta región de formación estelar ubicada a unos 6,500 años luz en la constelación de Casiopea. Esta toma ha sido procesada en paleta HOO, asignando tonos azules al oxígeno (OIII) y rojizos de hidrógeno (Ha), para resaltar las estructuras y contrastes de este impresionante objeto del cielo profundo.
La nebulosa del Alma es famosa por sus formas etéreas y complejas, moldeadas por los vientos estelares y la radiación de estrellas jóvenes y masivas. Su nombre proviene de la apariencia "humana" que algunos logran percibir entre sus nubes de gas y polvo.
🔭 Un viaje al corazón del cosmos, donde nacen las estrellas.

A pair of famous emission nebulae in the northern constellation of Cassiopeia, the Heart (IC 1805) and Soul (IC 1848) nebulae are huge clouds of (mostly) hydrogen gas swaddling clusters of hot new stars which are hollowing out the surrounding clouds. These nebulae are around 7,500 light years away from us, in the Perseus arm of our Milky Way galaxy.
This photo was taken with a William Optics Redcat51 telescope attached to an ASI 2600MC camera fitted with an Optolong L-eXtreme filter. The image is an integrated stack of 15 hours total exposure, post-processed in PixInsight.

IC 1805 Heart Nebula
The Heart Nebula, IC 1805, Sharpless 2-190, is some 7500 light years away from Earth and is located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. It was discovered by William Herschel on 3 November 1787. It is an emission nebula showing glowing ionized hydrogen gas and darker dust lanes. The brightest part of the nebula (a knot at its western edge) is separately classified as NGC 896, because it was the first part of the nebula to be discovered. The nebula's intense red output and its morphology are driven by the radiation emanating from a small group of stars near the nebula's center. This open cluster of stars, known as Collinder 26 or Melotte 15, contains a few bright stars nearly 50 times the mass of our Sun, and many more dim stars that are only a fraction of our Sun's mass.

In the constellation of Ursa Major, at about 25 million light years from us lies the Pinwheel Galaxy. This beautiful galaxy has 170,000 light years across, about twice of our Milky Way.
In the photo, two types of color clusters hint on the objects present: the red-pinkish ones are the hydrogen rich nebulas where star forming is taking place and the blue ones on the spiral arms are clusters of young and hot blue stars.
This photo is a cropped reprocessing of my previously published photo.

Después de un par de noches fallidas, en las que algo siempre salía mal, he podido hacer al fin una sesión de fotografía para sacar esta nebulosa.
La nebulosa Medialuna (NGC 6888), también llamada nebulosa Creciente o Caldwell 27, es una nebulosa de emisión en la constelación de Cygnus, situada 6º al suroeste de Sadr (γ Cygni). Se encuentra a unos 4700 años luz de distancia de la Tierra.
La nebulosa Medialuna es una nebulosa de Wolf-Rayet, formada por el fuerte viento estelar originado por la estrella de Wolf-Rayet HD 192163 (WR 136) que choca y dinamiza el viento más lento que expulsó la estrella cuando se convirtió en una gigante roja hace unos 400 000 años. A resultas de esta colisión se ha formado una envoltura y dos ondas de choque, una moviéndose hacia afuera y otra hacia dentro. La onda de choque que se mueve hacia el interior calienta el viento estelar hasta temperaturas en donde se emiten rayos X.

En la constelación Cepheus , la impresionante nebulosa de emisión IC 1396 mezcla el gas cósmico brillante y las nubes oscuras de polvo. Esta región de formación estelar , excitada por la estrella brillante y azulada que hay en el centro, se extiende cientos de años luz, abarca más de tres grados en el cielo y se encuentra a unos 3.000 años luz del planeta Tierra.
Entre las intrigantes formas oscuras de IC 1396, arriba en el centro, está la sinuosa nebulosa de la Trompa de Elefante.
La Nebulosa de la Trompa de Elefante es una concentración de interestelar gas y polvo dentro de la región de gas ionizado mucho más grande IC 1396 ubicada en la constelación Cefeo alrededor de 2.400 años luz lejos de la Tierra. La pieza de la nebulosa aquí se muestra el glóbulo denso y oscuro IC 1396A; Se la denomina comúnmente nebulosa de la Trompa de Elefante debido a su apariencia en longitudes de onda de luz visible, donde hay una mancha oscura con un borde sinuoso y brillante.
Ahora se cree que la Nebulosa de la Trompa de Elefante es un sitio de formación estelar, que contiene varias estrellas muy jóvenes (menos de 100.000 años) que fueron descubiertas en imágenes infrarrojas en 2003. Dos mayores (pero aún jóvenes, un par de millones de años) estándares de estrellas, que viven miles de millones de años) las estrellas están presentes en una pequeña cavidad circular en la cabeza del glóbulo.

This is the view I was after when the USB plug broke on the camera March last year. This proved to be a marathon getting images as the mount threw up a curveball and at this stage still not sure if I have found the answer to the problem.
This will be my last photo for a very long time as I do a huge panorama of the Milky way of some 40 odd shots. Enjoy it.

A super-widefield view of the nebulosity associated with the huge supernova remnant in the southern constellation of Vela, North is at the top in this frame which is a 2x2 mosaic where each pane of the mosaic was captured with a William Optics Redcat51 scope and a ZWO ASI2600MC camera. I built 2 versions of the mosaic, the first taken with just the built-in UV/IR filter and the second shot with an Optolong L-eXtreme filter. The final result is a blend of these two. All post-processing was carried out in PixInsight.

Se me ha quemado el núcleo de la nebulosa así que tendré que volver a realizar la toma bajando la ISO a 800, a ver si así aguanta.
La nebulosa de Orión forma parte de una inmensa nube de gas y polvo llamada nube de Orión, que se extiende por el centro de la constelación de Orión y que contiene también el bucle de Barnard, la nebulosa Cabeza de Caballo, la nebulosa de De Mairan, la nebulosa M78 y la nebulosa de la Flama. Se forman estrellas a lo largo de toda la nebulosa, desprendiendo gran cantidad de energía térmica, y por ello el espectro que predomina es el infrarrojo.
La nebulosa de Orión es una de las pocas nebulosas que pueden observarse a simple vista, incluso en lugares con cierta contaminación lumínica. Se trata del punto luminoso situado en el centro de la región de la Espada (las tres estrellas situadas al sur del cinturón de Orión), y debajo de la estrella iota de Orión ( para los habitantes del hemisferio sur terrestre ). que los astrónomos árabes llamaron Nair al Saif que en español significa : "La Espada Luminosa". A simple vista, la nebulosa aparece borrosa, pero con telescopios sencillos, o simplemente con prismáticos, la nebulosa se observa con bastante nitidez.
La nebulosa de Orión contiene un cúmulo abierto de reciente formación denominado cúmulo del Trapecio, debido al asterismo de sus cuatro estrellas principales. Dos de ellas pueden observarse como estrellas binarias en noches con poca perturbación atmosférica, efecto denominado seeing, lo que hace un total de seis estrellas. Las estrellas del cúmulo del Trapecio acaban de formarse, son muy jóvenes, y forman parte de un masivo cúmulo estelar con una masa calculada en 4500 masas solares dentro de un radio de 2 parsecs llamado cúmulo de la nebulosa de Orión, una agrupación de aproximadamente 2000 estrellas y con un diámetro de 20 años luz. Este cúmulo podría haber contenido hace 2 millones de años a varias estrellas fugitivas, entre ellas AE Aurigae, 53 Arietis, o Mu Columbae, las cuales se mueven en la actualidad a velocidades cercanas a los 100 km/s.
Los observadores se han percatado de que la nebulosa posee zonas verdosas, además de algunas regiones rojas y otras azuladas con tintes violetas. La tonalidad roja se explica por la emisión de una combinación de líneas de radiación del hidrógeno, Hα, con una longitud de onda de 656,3 nanómetros. El color azul-violeta es el reflejo de la radiación de las estrellas de tipo espectral O (muy luminosas y de colores azulados) sobre el centro de la nebulosa. El color verdoso supuso un auténtico quebradero de cabeza para los astrónomos durante buena parte de comienzos del siglo XX, ya que ninguna de las líneas espectrales conocidas podía explicar el fenómeno. Se especuló que estas líneas eran causadas por un elemento totalmente nuevo, y a dicho elemento teórico se le acuñó el nombre de «nebulium». Más tarde, cuando ya se poseía mayor profundidad en el conocimiento de la física de los átomos, se llegó a la conclusión de que dicho espectro verdoso era causado por la transición de un electrón sobre un átomo de oxígeno doblemente ionizado. Sin embargo, este tipo de radiación es imposible de reproducir en los laboratorios, ya que depende de un medio con unas características concretas solo existentes en las entrañas del espacio.

The often-photographed (certainly by me) area of the North America Nebula, NGC 7000, near the bright star Deneb, which is in the frame at right, in Cygnus. The Pelican Nebula, IC 5067/70 is right of the North America, in the “Atlantic Ocean” so to speak. The nebulosity at bottom is the “Cygnus Arc,” IC 5068. The small patch of blue reflection nebulosity at top is IC 5076. The patches of dark nebulosity above the North America Nebula are B352 and B356.
This is a stack and blend of: four exposures without a filter, each 8 minutes at ISO 800, and four exposures with an Optolong L-Enhance nebula filter to bring out the faintest nebulosity, each 16 minutes at ISO 1600. These are blended in with a Lighten mode. All were with the William Optics RedCat 51mm astrographic refractor at its native f/5 and Canon EOS Ra camera, the factory filter-modified camera capable of recording this type of hydrogen-alpha emitting nebulas. Guided with the ZWO ASIAir and ASI120MM guide camera, on the Astro-Physics Mach1 mount. Taken from home on a perfect summer night on August 15, 2020.
Another trip into space, this time to Orion that, at present, rises above the horizon late in the evening 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.

I am not fully satisfied with the result, due to the bright gradients, however I like how the emission nebulae are seen. Mosaic of 2 panels, each is the sum of 8 poses from 2 minutes to 1600 iso. Canon eos 700d not modified, Samyang 24 f2.0 lens and Uhc optolong filter. Minitrack Lx2
I was trying out some new equipment when I thought I would try Carina as it was over head. At one point I had to go inside the smoke was so strong and the Guiding got very bad. Only the Second shot I have done that was almost totally edited in PixInsight never see the amount of nebulocity around the main nebula. the mount stopped as the house next door got in the way enjoy the Southern hemisphere at 900mm. DSLR @ 600mm same scope.

Top right: the M4 Globular Cluster, s a dense sphere of stars (100,000), with an estimated age of 12.2 billion years. Located about 7,200 light-years away, it's one of the closest globular clusters to Earth. M4 is easily visible with binoculars and small telescopes, especially during the summer months. All the color? much closer. The Rho Ophiuchi cloud complex is a prominent star-forming region located about 400-460 light-years away in the constellation Ophiuchus, making it one of the closest to Earth. It's a vibrant, dynamic region composed of gas and dust, containing both bright reflection nebulae (blue light from stars scattered by dust) and darker areas where stars are being born.

The name of this one how could I resist. Has been a cloud fight to get the shots over 4 night in very strong winds. this sits just below the Horse head nebula and just off the red ring that goes around Orion. Barnards loop the goes around half of the Orion area, Barnards loop I will wait for moon less night to try and get this target with my 50mm F1.8 lens ZWOASI071.

SH2-308, commonly known as the "Dolphin Head Nebula" is a HII region located in the constellation Canis Major. It is approximately 4300light years away. he massive star that created the bubble, a Wolf-Rayet star, is the bright one near the center of the nebula. Wolf-Rayet stars have over 20 times the mass of the Sun and are thought to be in a brief, pre-supernova phase of massive star evolution. Fast winds from this Wolf-Rayet star create the bubble-shaped nebula as they sweep up slower moving material from an earlier phase of evolution.
This image was captured with a ASI 2600MC Pro OSC camera and a TS-Optics 90mm CF APO f.6 Refractor (543mm focal length). I used a optolong L-eXtreme filter to capture the narrowband data.
This was my first time shooting 1000s exposures! I think it turned out pretty great, although I only have about 4.1hrs on the target.

I present to you the awe inspiring core of the Andromeda (M31) galaxy. M31 is speeding toward us from 2.5 million light years away. It contains.... 1 TRILLION stars... twice the number of our own Milky Way!
From earth, Andromeda is 5 times the size of the full moon.

There are two smaller galaxies with it, M32 and M110.
Sure makes one feel humble!

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.

La Nebulosa Grotta (Sh2-155 o C9) è una splendida nebulosa a emissione situata nella costellazione di Cefeo, a circa 2400 anni luce di distanza dalla Terra.
Per questa immagine ho utilizzato filtri interferenziali dualband, che mi hanno permesso di realizzare una composizione in Hubble Palette: il rosso è assegnato allo zolfo ionizzato (S II), il verde all’idrogeno alfa (H α) e il blu all’ossigeno doppiamente ionizzato (O III).
Le pose guidate da 600 secondi sono state:
67 scatti con filtro Antlia ALP-T 5 nm, per H α e O III;
87 scatti con filtro Optolong L-Synergy 7nm, per S II e O III.
Per le stelle, 1 ora di integrazione in pose da 60 secondi con filtro broadband SV260.
Strumentazione utilizzata:
Telescopio Newton 150/600 con correttore Tecnosky 0.95×
Camera Tecnosky Vision 571C

The Cave Nebula (Sh2-155 or C9) is a splendid emission nebula located in the constellation Cepheus, about 2,400 light-years away from Earth.
For this image, I used dual-band interference filters, which allowed me to create a composition in the Hubble Palette: red is assigned to ionized sulfur (S II), green to alpha hydrogen (H α), and blue to doubly ionized oxygen (O III).
The 600-second guided exposures were:
67 shots with the Antlia ALP-T 5 nm filter, for H α and O III;
87 shots with the Optolong L-Synergy 7 nm filter, for S II and O III.
For the stars, 1 hour of integration in 60-second exposures with the SV260 broadband filter.
