Rosette Nebula - SHO
Located 5,200 light years away in the constellation Monoceros is the emission nebula called the Rosette Nebula.
This is my first actual start to finish - deep sky object project with plenty of data.
I set up my ASI 2600 MC Pro and TS Optics 90mm F6 APO Refractor Telescope in my front yard in North Centra Texas (Bortle 5). This photo is 126 - 5 minute long exposures, shot over three nights, then stacked together. Optolong L Extreme filter was used.I then simulated SHO by combining channels in Pixinsight.

Le condizioni meteo, nel periodo autunno-inverno non sono favorevoli per l'astrofotografia, soprattutto quando si è costretti ad acquisire tante ore di integrazione.
Mi ero dedicato alla "Nebulosa Mago"
(Sh2-142) associata all'ammasso aperto "NGC7380", ma non ho avuto la possibilità di acquisire le tante ore necessarie quando si utilizzano filtri a banda stretta.
Questa volta però ho pensato di unire insieme anche l'acquisizione fatta il mese precedente con un altro telescopio (Scopos TL805). Forse non ho aggiunto dettagli ma un pò di SNR l'ho guadagnato, ottenendo un'immagine gradevole e recuperando un discreto segnale debole Ha.

The weather conditions in the autumn-winter period are not favourable for astrophotography, especially when you are forced to acquire many hours of integration.
I had dedicated myself to "Wizard Nebula"
(Sh2-142) associated with the open cluster "NGC7380", but I did not have the opportunity to acquire the many hours necessary when using narrow-band filters.
This time, however, I thought of combining the acquisition made the previous month with another telescope (Scopos TL805). Maybe I did not add details but I gained a bit of SNR, obtaining a pleasant image and recovering a fairly weak signal Ha.

The Medusa Planetary Nebulais in the constellation Gemini and is about 1500 light years distant. It’s very old, very large and very dim (magnitude 16). The Medusa is roughly 12,000,000 times dimmer than the brightest star of the evening sky (Sirius at magnitude -1.4).
The Orion Nebula, possibly the most photographed deep sky object in the night sky. 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. M42 is located at a distance of 1350 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across and it has a mass of about 2000 times that of the Sun.

The "Cosmic Question Mark" is made up of two emission nebulae: NGC 7822 is at the top of the image, and SH2-170 is the circular nebula at the bottom.
NGC 7822 is a young star forming complex in the constellation Cepheus. It is about 2,935 light years from earth with a diameter of 300 light years.
SH2-170 is 7,500 light years away in the constellation Cassiopeia. It was discovered in the late 1950s on the 48 inch Schmidt telescope photo plates of the Palomar Observatory Sky Survey by the American astronomer Stewart Sharpless. The nebula is a diffuse H-II region ionized by a single main sequence O-type star visible at the center.
The image spans about 4.3 x 5 degrees and was shot as an 8 panel mosaic through an Ha filter with about 5 hours of exposure time for each panel.

Messier 37 is the richest open cluster in the constellation Auriga. It is the brightest of three open clusters in Auriga and was discovered by the Italian astronomer Giovanni Battista Hodierna before 1654. M37 was missed by French astronomer Guillaume Le Gentil when he rediscovered M36 and M38 in 1749. French astronomer Charles Messier independently rediscovered M37 in September 1764 but all three clusters were recorded by Hodierna. M37 is located in the antipodal direction, opposite from the Galactic Center as seen from Earth. It contains over 500 identified stars and its estimated distance of around 4,500 light-years from Earth.

NGC 281 è una nebulosa a emissione visibile nella costellazione di Cassiopea; circonda l'ammasso aperto IC 1590. Talvolta è chiamata Nebulosa Pacman. Si individua 1,5 gradi ad est della stella α Cassiopeiae; occorrono strumenti potenti per poter individuare la nebulosa, che sicuramente è l'oggetto più importante, dato che l'ammasso ad essa associato è formato da pochi astri e dominato da una stella doppia di ottava magnitudine. La nebulosa appare solcata nettamente da una vena scura, che la attraversa in senso est-ovest; perpendicolare a questa se ne individua un'altra, rivolta verso sud: viene così a formarsi una "T" che segna profondamente tutto l'oggetto.

NGC 2359, or Thor’s Helmet Nebula, is an emission nebula located in the constellation Canis Major. The central part of the nebula is thought to resemble the winged helmet worn into battle by Thor, the Norse god of thunder. Of course, your mileage may vary, i.e., I’ve had people seeing a spider from underneath, a baby owl, but not a helmet.
The nebula spans about 30 light years, making it 15 times larger than our solar system. It lies approximately 12,000 light years away from Earth and contains several hundred solar masses of gas. At its core is a Wolf-Rayet star, WR7, an extremely hot star estimated to be 16 times more massive than our Sun.
Wolf–Rayet stars are rare heterogeneous stars with unusual spectra showing prominent broad emission lines of ionized helium and highly ionized nitrogen or carbon. The spectra indicate very high surface enhancement of heavy elements, depletion of hydrogen, and strong stellar winds. The surface temperatures of known Wolf–Rayet stars range from 35,000 °F to around 378,000 °F, hotter than almost all other kinds of stars. The Sun’s surface temperature is about 10,000 °F.
All Wolf–Rayet stars are highly luminous objects due to their high temperatures -- thousands of times the bolometric luminosity (total energy output of an astronomical object across all wavelengths of electromagnetic radiation per unit time) of the Sun. They are not exceptionally bright visually, however, since most of their radiation output is in the ultraviolet. Think SPF 10000000000000000000…

Comet 67P Churyumov-Gerasimenko as it appeared on the night of November 2-3, 2021 in a good return near Earth, after its previous return in 2014-2015 when it was visited by the European Space Agency's Rosetta probe and Philae lander. The comet was faint — about 10th magnitude at this time, but did show a small tail on the photo and a typical cyan glow to its coma. The comet was in Gemini at this time. This is a Jupiter-family comet with a period of 6.45 years.

Just trying to figure out how much detail can be captured using the Williams Optics REDCAT on a wide field image. The Crescent Nebula is about 5,000 light years away from Earth. The Crescent Nebula was formed by the central star shedding its outer layers. According to NASA, “Burning fuel at a prodigious rate and near the end of its stellar life this star should ultimately go out with a bang in a spectacular supernova explosion”.

La Nebulosa di Orione (nota anche come Messier 42 o M 42, NGC 1976) è una delle nebulose diffuse più brillanti del cielo notturno. Chiaramente riconoscibile ad occhio nudo come un oggetto di natura non stellare, è posta a sud del famoso asterismo della Cintura di Orione,[6] al centro della cosiddetta Spada di Orione, nell'omonima costellazione.
Posta ad una distanza di circa 1270 al dalla Terra,[2] si estende per circa 24 anni luce[5] ed è la regione di formazione stellare più vicina al Sistema solare. Vecchie pubblicazioni si riferiscono a questa nebulosa col nome di Grande Nebulosa, mentre più anticamente i testi astrologici riportavano lo stesso nome della stella Eta Orionis, Ensis (la spada), che però si trova in un'altra parte della costellazione.[7] Si tratta di uno degli oggetti più fotografati e studiati della volta celeste,[8] ed è sotto costante controllo a causa dei fenomeni celesti che hanno luogo al suo interno; gli astronomi hanno scoperto nelle sue regioni più interne dischi protoplanetari, nane brune e intensi movimenti di gas e polveri.
La Nebulosa di Orione contiene al suo interno un ammasso aperto molto giovane, noto come Trapezio.[9] Le osservazioni con i più potenti telescopi (specialmente il Telescopio spaziale Hubble) hanno rivelato molte stelle circondate da anelli di polveri, probabilmente il primo stadio della formazione di un sistema planetario.
La nebulosa è stata riconosciuta come tale nel 1610 da un avvocato francese, Nicolas-Claude Fabri de Peiresc (1580-1637),[10] anche se, date le dimensioni e la luminosità, era certamente conosciuta anche in epoche preistoriche. Tolomeo la identificava come una stella della spada di Orione, di magnitudine 3.

NGC 7044 in Cygnus
Found this little cluster when I was doing my NGC7000 mosaic
flic.kr/p/27HZQZf and I wanted to give it more attention. It is not seen in the mosaic however and I caught it by accident. It's located 10,000 ly away in the constellation of Cygnus.
Captured on 7/9, 7/14,8/4 and 8/6

This image shows a molecular cloud field in constellation Pegasus. This molecular cloud takes the shape of ghostly wisps, is located just outside our own galaxy and is called IFN - integrated flux nebula. This means that they reflect the combined luminosity of the stars in our galaxy and are, therefore, made visible.
But lurking in “between” these clouds, several galaxies are visible, being the largest one NGC 7497, located at about 60 million light years - a closer look will allow us to identify some of them. Despite appearances, these are located much farther than MBM54, which is at about 1,000 light years away.
This landscape has been on my target list for almost 8 months and only now it shows on the right position to photograph. But I also had the luck of being on a dark site during New Moon which helped tremendously. Astrophotography is indeed a hobby of patience and also some luck.

NGC 7293 is a bright planetary nebula, and one of the most recognizable and iconic deep sky objects in the sky through photography (thanks to Hubble)!
This image is 16 x 5-minutes using a ZWO ASI294MC Pro Camera and Sky-Watcher Esprit 100 telescope.
Thanks for looking!
The California Nebula, catalog number NGC 1499, owes its name to its resemblance to its American state counterpart.
It is a diffuse nebula more than 100 light years long located in the constellation of Perseus, in the outer part of the Orion arm of our galaxy about 1000 light years from the solar system. The region is extremely rich in ionized hydrogen, which makes it an area of high star formation, with stars that have a mass even 50 times greater than the Sun.
In this image I used the technique made famous by NASA with its Hubble Space Telescope called SHO or Hubble Palette.
This technique involves the use of interference filters which serve to isolate the three elements of which the emission nebulae are composed.
Ionized oxygen (Blue color)
Ionized hydrogen (Green color)
Ionized sulfur (yellow orange color)
I tried to keep the palette as scientifically faithful as possible in order to make the separation of the three physical elements evident at the expense of the artistic rendering, so I kept the green tones and a bit of magenta on the stars.

47 Tucanae (NGC 104) ou apenas 47 Tuc é um aglomerado globular situado na constelação de Tucana. Está a de cerca de 16 700 anos-luz de distância da Terra, e tem 120 anos-luz de diâmetro. Pode ser visto a olho nu, e é brilhante o suficiente para ganhar uma designação de Flamsteed com uma magnitude visual de 4,0. É apenas uma de um pequeno número de características com essa designação do céu do sul.
47 Tucanae foi descoberto por Nicolas Louis de Lacaille em 1751; a sua localização muito ao sul tem escondido de observadores europeus até então. O aglomerado aparece aproximadamente com o tamanho da lua cheia no céu em condições ideais.
É o segundo aglomerado globular mais brilhante no céu (depois de Omega Centauri), e é conhecido por ter um núcleo muito brilhante e denso. Ele tem de 22 pulsares milisegundos conhecidos, e pelo menos 21 estrelas retardatárias azuis (blue stragglers) perto do centro.[4]
47 Tucanae está incluído no Catálogo Caldwell de Sir Patrick Moore como C106.
NGC 104 concorre com NGC 5139 (Omega Centauri) para o título: O mais esplêndido Aglomerado Globular no céu. NGC 104 tem duas características em seu favor. Ele é arredondado e tem um centro mais compacto. No entanto, devido à localização, mais observadores vão para NGC 5139.

Happy New Year to you all !
Messier 45, also known as the Pleiades or Seven Sisters, is a bright open star cluster located in the constellation Taurus. The Pleiades cluster lies at an average distance of 444 light years from Earth.
M45 contains a number of hot, blue, extremely luminous stars and is one of the nearest star clusters to Earth. It is the easiest object of its kind to see without binoculars.
M45 has a core radius of 8 light years and its tidal radius extends to about 43 light years. The total mass of M45 is estimated at about 800 solar masses.
At the end of October, I had 2 almost clear nights, and decided to spend it on the Pleiades, as last year the weather didn't allow it.
I was really not happy with framing from the first night (some "recentering" issues after the Meridian Flip), so I took the right panel during the second night. A bit overkilled I know :p
I had to drop a lot of my subs (+/- 50%) due to clouds, so the Exposure Time is not as I wanted.
Best Wishes & Clear Skies :)
