Nel braccio del Perseo della nostra Galassia che si proietta nella costellazione di Cassiopea si trova questa nebulosa che ricorda la chela di un'aragosta. La parte settentrionale forma una sorta di anello per via del vento stellare di stelle giganti.
Esposizioni da 10 minuti per ciascun filtro, 73 per il dualband Antlia ALP-T 5 nm e 52 per l'Optolong L-Synergy. L'elaborazione scelta è la Hubble Palette SHO dove lo zolfo ionizzato (Sii) va nel canale rosso, l'idrogeno ionizzato (H-alfa) nel verde l'ossigeno due volte ionizzato (Oiii) nel blu.
Per catturare le stelle è stata aggiunta circa un’ora di integrazione in pose da 60 secondi con filtro broadband SV260.
L'integrazione totale arriva aquasi 22 ore complessive.
Il tutto è stato ripreso con un telescopio Newton 150/600 dotato di correttore Tecnosky 0.95x, camera Tecnosky Vision 571C e montatura EQ6-R Pro, elaborazione in PixInsight.
This nebula, reminiscent of a lobster's claw, is located in the Perseus arm of our Galaxy, which extends into the constellation Cassiopeia. Its northern portion forms a ring due to the stellar wind from giant stars.
10-minute exposures were taken for each filter: 73 for the dual-band Antlia ALP-T 5 nm and 52 for the Optolong L-Synergy. The Hubble Palette SHO processing was chosen, where ionized sulfur (Sii) is in the red channel, ionized hydrogen (H-alpha) in the green, and doubly ionized oxygen (Oiii) in the blue.
To capture the stars, about an hour of integration was added in 60-second exposures with the SV260 broadband filter.
The total integration time comes to almost 22 hours in total.
The whole thing was captured with a 150/600 Newtonian telescope equipped with a Tecnosky 0.95x corrector, a Tecnosky Vision 571C camera and an EQ6-R Pro mount, processed in PixInsight.
NGC 2903
.................
Discovered over 200 years ago by astronomer William Herschel, this galaxy is just over 30 million light-years away and can be seen during the spring nights in the constellation Leo. NGC 2903 is very similar to our galaxy in both size ( abt 100.000 light years diameter) and structure, with both galaxies being classified as "barred galaxies”. What makes it stand out (or not, in terms of popularity) is its position in night sky, being a "field galaxy" or solitary galaxy, meaning it is not part of a larger group of galaxies and is not affected by any external gravitational force, thus being gravitationally alone.
I think that, despite its "shy" position in deep space, this galaxy deserves a popular name, especially since it is not an impossible target, a focal length of 5-600 mm being able to bring out some details.

wasn't happy with the last rendition, so i processed it again with some differences. :)
Same data and kit.
IC1805 is the open star cluster that lies in the center of the heart nebula.
The heart shape itself is not so recognizable here due to the small FOV cropping the outer areas off. This central area has some nice detail surrounding the star cluster.
The image was taken over two different nights, one night for h-alpha data, and another for the OIII.

Dopo più di due mesi sono riuscito a lavorare queste riprese sulla Cometa C/2025 Swan. Che abbia trovato il tempo proprio la sera di Natale è un caso , comunque una caso piacevole!
Sono solo 12 minuti di pose guidate da 30 secondi mentre la cometa passa in campo ricco di stelle della nostra Via Lattea la sera del 17 ottobre.

After more than two months, I managed to complete these shots of Comet C/2025 Swan. That I found the time on Christmas Eve is a coincidence, but a pleasant one nonetheless!
It's just 12 minutes of 30-second guided exposures as the comet passes through the star-filled field of our Milky Way on the evening of October 17th.

M42 The Orion Nebula and NGC 1977 The Running Man Nebula and M43 captured this time with a longer lens which I wanted to experiment with.
Using the 150-600mm Tamron G2 lens at 600mm I knew I was pushing my star tracker beyond the limits but even without autoguiding I was still able to get some usable images. I stacked a series of various exposure lengths creating 3 images using Siril and in Photoshop stacked and edited them before moving to Lightroom to finish off.

Lonely galaxies watch a passing comet slip away through the integrated flux.
This is a shot from May of this year. The comet is C/2017 T2 (PANSTARRS), not the current superstar comet C/2020 F3 (NEOWISE). T2 PANSTARRS spent three nights drifting past galaxies M81 and M82 before moving on. I caught this on the middle of those three nights. Unlike NEOWISE, T2 PANSTARRS was never bright enough to see unaided, and required a very long lens or small telescope to effectively photograph, so images of T2 PANSTARRS are comparatively rare. As you can see, the two comets feature very different tails. 2020 has already proven to be quite the year for Comets.

Reprocess with a couple extra exposures added to the stack. editing in PS, stacked in deepskystacker 3.4 same kit as before. managed to bring more of the brown/golden dust and blue reflection nebula out as well as the main nebula itself. quite happy with this one i think. :P
Not bad for 35 minutes' worth of exposure.

I mount my Nikon lens and camera on top of my optical tube at the moment. There was a constant wind of ~5mph last night when I took my images. I did 33 light frames and used the best 90% for 30 frames. I polar aligned with SharpCap and began guiding. The graph looked good so I started imaging. The stars seemed to stay in focus so I upped my exposure to 212 seconds and let it go to work. After stacking the files in DeepSkyStacker I pulled the TIFF file into Photoshop and mostly followed along to AstroBackyard's Rosette Nebula tutorial, making some of my own adjustments where they were needed. I'm still struggling with color of the surrounding stars. My WB was set to automatic, that might be why the color is a bit hard to manage. The Moon did rise while I was imaging and I can see a difference in my light frames, I'm sure I can do better and might try again during a new moon. But for my first time trying M101 and autoguiding I'm pretty happy!

NGC 6946, conosciuta come la *Fireworks Galaxy*, è una delle galassie a spirale più affascinanti del cielo boreale. Situata a circa 22 milioni di anni luce, al confine apparente tra le costellazioni di Cefeo e del Cigno, mostra bracci ricchi di polveri scure, regioni di intensa formazione stellare e un nucleo relativamente tenue, caratteristiche tipiche delle spirali tardive ma qui particolarmente accentuate.
La sua fama è legata a un primato straordinario: è una delle galassie con il maggior numero di supernovae osservate in epoca moderna, ben dieci eventi confermati nell’ultimo secolo. Un dato eccezionale, che testimonia un tasso di nascita e morte stellare insolitamente elevato. Non a caso, NGC 6946 è un vero laboratorio cosmico per lo studio dell’evoluzione stellare e dei cicli di vita delle stelle massicce.
Una curiosità affascinante è che, nonostante la sua luminosità intrinseca, questa galassia appare più debole del previsto a causa delle dense nubi di polvere della Via Lattea che si frappongono lungo la linea di vista. Fotografarla dalla città è quindi una sfida tecnica notevole, che rende ancora più gratificante riuscire a far emergere la delicata struttura dei bracci e le sfumature diffuse del disco.
Un’esplosione silenziosa, lontana milioni di anni luce, che continua a raccontare storie di stelle, energia e trasformazione cosmica.
Dati tecnici: ripresa effettuata dalla città con telescopio Newton 200 mm, camera ZWO ASI 533 MC a colori e filtro SV240 per il contenimento dell’inquinamento luminoso; integrazione totale di 90 minuti, scelta che ha permesso di far emergere la struttura della galassia e le regioni più luminose di formazione stellare nonostante il cielo urbano.

This is IC 2177, the Seagull Nebula. I shot it from my back yard in Bend, OR.
I used a 90mm f/6 triplet refractor equipped with a field flattener and mounted on an Orion Sirius EQ-G mount. The camera was a modified Canon 6D. I also used an Optolong L-Enhance dual-band filter to block out light pollution. Polar alignment, telescope focus, object acquisition, autoguiding, and exposure capture were all done from my iPhone using the ZWO ASIAir Pro.
I combined 30 300s exposures at f/6, ISO 2000, for a total of 2.5 hours of exposure time. Images and calibration frames were stacked in Astro Pixel Processor and finished in Lightroom and Photoshop.

For some scary summer fun, and with a nod to it being Shark Week on Discovery Network, I shot the Shark Nebula (LDN 1235) in Cepheus. It was first light with my new ASI2600MC Pro cooled astro camera, used with an Orion ED80T (f/6) carbon fiber triplet refractor right from my back yard in Bend, OR. I did not use any filters for this image. The image consists of 123 exposures of 5 minutes each, for a total of 10.25 hrs of integration (this thing is faint)! Light frames and calibration frames were stacked in Deep Sky Stacker, and the combined image was processed using Photoshop and Topaz Denoise AI, and a few of Annie's Actions. This is a first swipe at processing Celestial Jaws. He needs work, but I'll save that for another day.
This is my first attempt to track and capture M31 The Andromeda Galaxy. Located in the constellation of Andromeda and is the closest galaxy to our own. The small galaxy to the lower left of M31 is M110.
This was captured from by back garden using a 70-200 2.8 G2 lens (at 200mm) attached to a Nikon D750 mounted to a Skywatcher Star Adventurer 2i. I took 23 images ranging in exposure time from 90 secs up to 189 secs (32 mins total) all at f4 and ISO 800 and then stacked in Deep Sky Stacker and edited in Lightroom.
I must admit for a first attempt I am pretty impressed at what I have captured although for more detail I will need to take a lot more images so more work to be done.
Thank you very much to you all and hope you like what I captured.

This is an open cluster, close to the Eta Carina nebula. It is already beautiful to the naked eye, showing stars of different colors. But through long exposures, it looks spectacular!
I really think this is one of the most beautiful open clusters in the night sky. The residual nebula that glows in H-Alpha brings an incredible complexity to this DSO.
By the way, I was very happy to be able to record this surrounding nebula. It is much darker than the other nebulae that I am used to photograph, and the heap of stars around it makes it even more difficult.

Used a stock camera(Nikon D5600) with a very close spectral response similar to the human eye. Hydrogen emission nebulae actually appear pink due to H-alpha (red), H-beta (blue) and emission from other atoms, like oxygen and sulfur. Orange faint nebulosity is the dust clouds.

So, that's finally my last capture before I get my DSLR modified for astrophotography.
Of course, my ideia is to shot an emission nebula hard to capture with a stock camera.
If everything ends right, soon I'll post a version of this same target, with some quite similar exposure, but with an astromoded Canon T6i.
Wish me luck!
Well... what a hard target for a Bortle 6 skies and a stock DSLR. Almost 3 hours of exposure and I hardly got some nebulosity. I hope it will change soon, as soon my camera come back and my Optolong L-Pro arrive.
Bubble nebula , a favourite of mine, tried several times to capture this well, but only recently managed to improve on it by using longer exposures with the new mount. :) cropped to hide field curvature :P

A misty moonlit night was a poor time to try RGB, imaging but without any nebulae in my part of the sky at that time i decided to give it a shot, i chose a star cluster for 2 reasons - bright enough to show up in short exposures, and wouldn't require much stretching during post-processing.

Orion a.k.a. Messier 42, the most famous nebula in the night sky in both the northern and southern hemispheres, can be found in the constellation Orion and can be seen (literally) from August to April. Orion can be seen with the naked eye from low light pollution locations, but a simple pair of binoculars is more than enough to be observed in the middle of Orion's Sword.
M42 is about 1300 light-years away from Earth, has an apparent diameter of 12 light-years, and is considered by far one of the most popular targets in astrophotography, along with Andromeda Galaxy.
I took this picture from a Bortle 2-3 location, using "advanced amateur" equipment and is without any doubts my best Orion image so far.
Equipment and settings:
Mount: SW EQ6R
Telescope: SW 72ED
Camera: ASI 533 MC Pro.
Total exposure: 102 min
Stacked with Deep Sky Stacker. Edit in Pixinsight.

If i have this right, this image is a L(Ha+R)GB image. That is, i used .Luminance and RGB filters with a bit of hydrogen alpha mixed with the red channel.
I have wanted to image this area again ever since i first did with my old 350D and the last two clear nights (with no full moon) were the perfect opportunity for me to give it a shot.
It's a nice reflection nebula (blue) in the center of some emission nebulosity in Cygnus.
Used my ED80 - QHY163M - Optolong filters and processed in photoshop.
I'm quite happy with the result, although several different versions of it are on my laptop, some better than others and this one happens to be my favourite for the moment, but that will quickly change :D
