M52, an open star cluster, and NGC 7635, an emission nebula, lie within about 2 degrees of each other in the constellation, Cassiopeia. This picture combines two image sets captured on consecutive nights, one with a filter designed to enhance the visibility of emission nebulae, and the other without the filter to capture more "natural", vibrant star colors.

Another astro image - the clouds cleared last night, despite the forecast saying it would be overcast, so I stayed up all night and grabbed 6 hours or data collection on Andromeda. It's not finished as I need to collect further data to refine the image further and collect some data in the hydrogen (red) spectrum to show the nebulae within the spirals. So it's a work in process but still my best to date on this celestial object.

The Andromeda Galaxy (M31) is a barred spiral galaxy approximately 2.5 million light-years from Earth and the nearest major galaxy to the Milky Way. The galaxy's name stems from the area of Earth's sky in which it appears, the constellation of Andromeda.

The mass of the Andromeda Galaxy is of the same order of magnitude as that of the Milky Way, at 1 trillion solar masses and it has a diameter of about 220,000 light years.

The number of stars contained in the Andromeda Galaxy is estimated at one trillion, or roughly twice the number estimated for the Milky Way.

The Milky Way and Andromeda galaxies are expected to collide in around 4.5 billion years, merging to form a giant elliptical galaxy or a large lenticular galaxy.

Also visible in this shot are two satellite dwarf galaxies, M32 and M110 (the two other fuzzy star formations to the left and just below Andromeda).

Sh2-132, es una enorme nebulosa de emisión muy débil, situada en la zona sur de la constelación de Cefeo, se encuentra a una distancia de unos 10.400 años luz, en el interior del brazo de Perseo. Las estrellas responsables de la ionización del gas son muy calientes y masivas; en particular, se han identificado dos estrella Wolf-Rayet, llamadas HD 211564 y HD 211853, así como una estrella de clase espectral y una docena de estrellas de clase B. Alrededor de la estrella de tipo O y una de las estrellas Wolf-Rayet crece una burbuja claramente visible en la banda de ondas de radio, llamada Shell B, probablemente se originó a partir del viento estelar de las dos estrellas masivas.

Sh2-132, a huge, very faint emission nebula, located in the southern part of the constellation Cepheus, is at a distance of about 10,400 light-years, inside the Perseus arm. The stars responsible for the ionization of the gas are very hot and massive; in particular, two Wolf-Rayet stars, named HD 211564 and HD 211853, as well as one spectral class star and a dozen B-class stars have been identified. Around the O-type star and one of the Wolf-Rayet stars grows a clearly visible bubble in the radio waveband, called Shell B, probably originated from the stellar wind of the two massive stars.

Finalmente era giunto il momento di dedicarmi alla famosa ed interessante Nebulosa Velo, chimata anche Cygnus Loop, Nebulosa Cirri e nebulosa Filamentaria. E' ciò che rimane dell'esplosione di una supernova avvenuta crca 10.000-20.000 anni fa.

Questa nebulosa diffusa, tuttora in espansione, ricchissima di Ha, OIII e S è molto vasta e per fotografarla nel suo insieme occorrono corte focali, ma focali più lunghe permettono di evienziarne gli intrecci e filamenti che la compongono anche se si è costretti ad inquadrarne solo una parte.

L'avevo già fotografata nel 2014 (flic.kr/p/oU4mqe) e nel 2024 (flic.kr/p/2q9HMCi) con il teleobiettivo Zenit Jupiter 11-A focale 135mm; in questa occasione ho fotografato con focale 420mm la parte orientale, alla quale sono state assegnate le sigle NGC6992, NGC6995 e IC1340.

Grazie alla sua luminosità l'elaborazione non è stata molto laboriosa anche se non è stato facile evidenziare anche le parti molto evanescenti.

Questo appagante risultato lo voglio dedicare a mio padre, che è venuto a mancare il 18 agosto scorso. Lui non era attratto da questo mio hobby, ma mi piace pensare e sperare che da lassù adesso possa godersi questo spettacolo dell'universo. Ciao papà!

________

The time had finally come to dedicate myself to the famous and interesting Veil Nebula, also called Cygnus Loop, Cirrus Nebula and Filamentary Nebula. It is what remains of a supernova explosion that occurred approximately 10,000-20,000 years ago.

This diffuse nebula, still expanding, rich in Ha, OIII, and S nebulae, is very large and requires short focal lengths to photograph it as a whole, but longer focal lengths allow you to highlight the interweavings and filaments that compose it even if you are forced to frame only a portion.

I had already photographed it in 2014 (flic.kr/p/oU4mqe) and in 2024 (flic.kr/p/2q9HMCi) with the Zenit Jupiter 11-A telephoto lens with a focal length of 135mm; On this occasion, I photographed the eastern portion with a 420mm focal length, which was assigned the designations NGC6992, NGC6995 and IC1340.

Thanks to its brightness, processing wasn't very laborious, although it wasn't easy to highlight even the very faint parts.

I want to dedicate this satisfying result to my father, who passed away on August 18th. He wasn't drawn to this hobby of mine, but I like to think and hope that from up there he can now enjoy this spectacle of the universe. Goodbye, Dad!

C/2022 E3 (ZTF) is a long period comet from the Oort cloud that was discovered by the Zwicky Transient Facility on 2 March 2022. The comet has a bright green glow around its nucleus which is due to the effect of sunlight on its molecules, especially diatomic carbon and cyanogen.

The comet reached its perihelion on 12 January 2023, at a distance of 1.11 AU (166 million km; 103 million mi), and the closest approach to Earth will be on 1 February 2023, at a distance of 0.28 AU (42 million km; 26 million mi). The comet exceeded magnitude 6 and is dimly visible with the naked eye as a small diffuse smudge under a dark enough sky, but most viewers will need an instrument such as binoculars. A magnitude 5 star is easier to see than a magnitude 5 comet because the comet has a low surface brightness and we see the same total amount of light from the comet as we would from a star with the same magnitude. The first quarter moon occurred on 28 January and will further obscure viewing the comet without optical aid.

This is a wide-field image of Lagoon (M8) & Trifid nebulae (M20) in Sagittarius constellation. These nebulae are both star nurseries. The Lagoon nebula is emission nebula mainly composed of Hydrogen gas. The black focal spots in the nebula are protostar collapsing dust clouds called Bok globules. The nebula is brightened by two giant stars in the centre and the open star cluster NGC 6530 above it. In the other side, the Trifid nebula which is composed of Red emission nebula & Blue reflection nebula. It’s called trifid because the dark dust lanes are separating the nebula into three lobes. Its about 5,200 light years distance. Gear setup: WO Redcat51 f/4.9, Optolong L-Pro, ZWO ASI 2600 MC, iOptron Sky Guider Pro unguided, ASIair. Acquisition 20 x 180 sec subs, 20 Darks, 50 Bias.

Continua la mia nuova esperienza con il Celestron SC C8, e dopo averlo provato con la "M16" l'ho puntato su un'altra famosa nebulosa nella stessa zona di cielo: la bella "Nebulosa Trifida", catalogata come "Messier 20" o M20 e come NGC 6514. Distante circa 5000 anni luce si trova in piena Via Lattea nella costellazione del Sagittario ed è facilmente osservabile con piccoli strumenti amatoriali. Grazie anche alla sua luminosità è uno degli oggetti DS più fotografati dagli astrofili.

Malgrado alcune difficoltà oggettive (autoguida, seeing, trasparenza del cielo, Inquinamento luminoso...) ho cercato di estrapolare tutto il segnale possibile e migliorarla esteticamente.

My new experience with the Celestron SC C8 continues, and after trying it with "M16", I pointed it at another famous nebula in the same area of the sky: the beautiful "Trifid Nebula", cataloged as "Messier 20" or M20 and as NGC 6514. About 5,000 light-years away, it is located in the Milky Way in the constellation Sagittarius and is easily observed with small amateur instruments. Thanks in part to its brightness, it is one of the most photographed DS objects by amateur astronomers.

Despite some objective difficulties (autoguiding, seeing, sky transparency, light pollution, etc.), I tried to extract as much signal as possible and improve its aesthetics.+

Wednesday’s forecast promised crystal-clear skies, and I couldn’t resist the call of this magical spot. As soon as I saw it, I jumped into action, pulling together a last-minute plan for a return visit.

Even with an early start, rush hour traffic had other ideas, and I arrived later than planned. Scouting quickly became a race against time, but thankfully, my previous visit gave me a solid head start. After exploring a bit, I found a couple of spots perfect for capturing the #milkyway rising verticalling and framed against the southern horizon.

This shot is a 5x5 35mm pano, capturing one of the smaller ponds around #lakeninan—a serene reminder of how patience and planning can lead to magic.

Nebulosa Pellicano (anche nota come IC 5067/70) è una regione H II visibile nella costellazione del Cigno, vicino a Deneb (la coda del cigno e la sua stella più brillante); appartiene alla stessa nube molecolare gigante della vicina Nebulosa Nord America ed è facilmente fotografabile. Al suo interno sono attivi fenomeni di formazione stellare, come testimoniato specialmente dalla presenza di oggetti HH; questi fenomeni riguardano principalmente stelle di piccola e media massa. La Nebulosa Pellicano, anche se più piccola e meno appariscente della vicina Nebulosa Nord America, appare con facilità in un telescopio amatoriale meno di un grado a sudovest di quest'ultima, da cui è separata da una banda oscura nota come LDN 935; fotografie eseguite con ingrandimenti via via maggiori consentono di rilevare sempre più particolari, sebbene se ne perda la visione d'insieme. Nonostante la sua luminosità, comunque, quest'oggetto resta al di fuori della portata della gran parte dei binocoli, ad eccezione di quelli più potenti. Grazie alla sua particolare forma, è uno degli oggetti nebulosi più noti e fotografati nell'emisfero nord.

La nebulosa si trova nell'emisfero celeste boreale a una declinazione molto settentrionale, presentandosi circumpolare dalle latitudini di città come Parigi e Vienna; la sua osservazione è pertanto molto facilitata per gli osservatori situati nell'emisfero boreale, dove si presenta generalmente molto alta nel cielo e addirittura allo zenit lungo il 44º parallelo nord. Dall'emisfero australe invece appare sempre piuttosto bassa sopra l'orizzonte settentrionale e diventa invisibile a sud del 46º parallelo sud. La nebulosa ricorda un pellicano, a causa di una nebulosa oscura che segna il bordo settentrionale dell'oggetto, facendolo così rassomigliare ad un becco di pellicano; si tratta da un punto di vista astronomico di una nebulosa ad emissione, molto studiata a causa dei fenomeni di formazione stellare che avvengono al suo interno. A causa delle forti dinamiche dei suoi gas, la nebulosa varierà forma relativamente in fretta. Riprese dal Giardino di casa del 03 06 2022.

This uses 6 60s stacks each of R, G, and B filter images. The best 58% of frames in red stacks were used along with the best 42% of frames in green and blue stacks. Captured with a Celestron Edge HD 925 with a ZWO ASI120MM camera and Optolong RGB filters using FireCapture 2.5. Stacking done in AutoStakkert, initial processing in PixInsight, derotation and channel combination in WinJUPOS, final processing in Photoshop and Topaz Labs.

Central meridian on Mars is 25° in this image. The area explored by the Opportunity rover is just to the right of center, in that brighter peninsula that juts downward in the dark features. There's some interesting weather happening near the north polar cap (at top), and it looks like there are some clouds about to rotate into view at the lower left.

C/2022 E3 (ZTF) est une comète à longue période qui a été découverte par le Zwicky Transient Facility le 2 mars 2022. Elle a atteint son périhélie le 12 janvier 2023, à une distance de 1,11 ua, et sera au plus près de la Terre le 1er février 2023, à une distance de 0,28 ua.

C/2022 E3 (ZTF) is a long-period comet from the Oort cloud that was discovered by the Zwicky Transient Facility on 2 March 2022.[1] The comet has a bright green glow around its nucleus, which is due to the effect of sunlight on its molecules, especially diatomic carbon and cyanogen.

I haven't shot the SMC much as I think it often looks a bit dull, but having been inspired by a shot by Jarrod Rueff I thought I would try part of it with RGB colour and dual narrowband luminance! 22.5 hours across the 4 filters, Takahashi FSQ106N telescope, QHY268M camera, Astronomik RGB filters, Optolong dual narrowband filter, Proxisky UMi20S EQ mount, processing in APP and PS. Shot at the Spet ASSA astro camp at Bendelby, South Australia.
