“NGC 247 also known as Caldwell 62 and commonly known as the Claw Galaxy is an intermediate spiral galaxy (although it is sometimes classified as a dwarf spiral galaxy) about 11.1 Mly away in the constellation Cetus. NGC 247 is a member of the Sculptor Group, and is 70,000 light years in diameter.
NGC 247 has an unusually large void on one side of its spiral disk. This void contains some older, redder stars but no younger, bluer stars.” Wikipedia

A complete rework and framing from my previous version of the Pleaides.
This version was to show more of the dust clouds surrounding the reflection nebula which is just as interesting as the star cluster and it's nebula itself.

First completed image of 2021. A bright and basic target, but one I have not yet imaged in my astrophotography career. Figured it'd be a good one to test out the new QHY 268M camera on. Half the data came from my old ASI1600mm and the other half from the 268M. Overall, this 268M is an absolutely phenomenal camera. Cannot wait to use it under dark skies.
I didn't match the rotation between the Ha and Oiii subs, but wanted to keep the outer nebulosity so I didn't crop the corners out.

Hi Folks,
I'm happy to say that I have completed my Image Reprocessing Project on SH2-101 - The Tulip Nebula - 12.8 hours of SHOrgb data.
This object is located approximately 6000 light-years away in the constellation of Cygnus (The Swan).
As promised, the Project post contains all of the image details and - most importantly - a complete image processing walkthru - is included in the project posting below:
cosgrovescosmos.com/projects/sh2-101-the-tulip-nebula-202...
How do you like the final version?
I was able to bring out a lot of very subtle details that could not be seen in the original!
Thanks,
Pat
E' incredibile ma vero. Avevo acquistato lo Schmidt-Cassegrain Celestron C8 (203mm f/10) nel 2000 e non lo avevo mai provato per la fotografia Deep-Sky. Neanche dopo aver acquistato il suo riduttore-correttore 0.63x, perchè non solo il suo campo corretto è più piccolo del formato APS-C ma ero anche convinto che la mia HEQ5-pro non fosse in grado di gestirne adeguatamente il peso e la guida. La ASI533MC-P, con il suo sensore da 1" (11.31x11.31mm) mi ha spinto a provare.
Ho iniziato con un target luminoso e quale migliore occasione che ripuntare la nebulosa M16?
Il controllo con la HEQ5 è al limite e alcune volte le oscillazioni per le folate di vento creano problemi. L'autoguida fa quello che può e la turbolenza spesso non mi ha aiutato.Forse un'ottica adattiva potrebbe fare miracoli, ma sono comunque rimasto piacevolmente sorpreso da questo primo rsultato ottenuto. Comunque c'è da dire che è stato un grande vantaggio per me avere sul tetto di casa "l'ossservatorio", che mi ha semplificato molto il processo di acquisizione, composto da 4 sessioni fotografiche.
I Pilastri della Creazione, la Guglia stellare, le nebulose oscure che si stagliano nel vasto tappeto di emissione Ha e i contorni delle nubi di idrogeno: questo spettacolo visto con una focale di 1260mm è stato veramente appagante.
Per i dettagli sulla Nebulosa Aquila vi rimando all'immagine flic.kr/p/2reF7PA
___________________
It's incredible but true. I purchased the Celestron C8 Schmidt-Cassegrain (203mm f/10) in 2000 and had never tried it for deep-sky photography. Not even after purchasing its 0.63x reducer-corrector, because not only is its corrected field smaller than that of an APS-C format, but I was also convinced that my HEQ5-pro wouldn't be able to adequately handle its weight and guiding. The ASI533MC-P, with its 1" sensor (11.31x11.31mm), encouraged me to try.
I started with a bright target, and what better opportunity than to refocus on the M16 nebula?
Control with the HEQ5 is at its limits, and sometimes the oscillations caused by gusts of wind create problems. The autoguider does what it can, and the turbulence often didn't help. Perhaps adaptive optics could work miracles, but I was still pleasantly surprised by this first result. However, it must be said that it was a great advantage for me to have "the observatory" on the roof of my house, which greatly simplified the acquisition process, which consisted of 4 photographic sessions.
The Pillars of Creation, the Stellar Spire, the dark nebulae that stand out in the vast carpet of Ha emission and the outlines of hydrogen clouds: this spectacle seen with a focal length of 1260mm was truly rewarding.

The Lobster Claw Nebula is an emission nebula located around 11,000 light-years from Earth in the constellation of Cassiopeia. The deep red and yellow regions are formed of Hydrogen Alpha with the blue regions being composed of double ionised oxygen. It’s located very close to NGC 7635 or Sh2 162 the Bubble Nebula, an image I recently posted.
4 good nights in a row at the complex in Los Coloraos, Spain for this little gem.
I decided to have a little creative fun with colour mapping the L-Ultimate narrow band filter. Most of the processing was done in PixInsight including the calibration, stacking, combining, deconvolution etc before send over to Photoshop for some palette mixing and recombining of the stars.
Perhaps not to everyone’s taste, but I loved the way it turned out which I guess in the end is why we do this hobby.

The Crescent Nebula is located in the heart of the summer constellation Cygnus, literally immersed in a "sea" of ionized hydrogen in which it appears to float. It is located approximately 5,000 light-years from Earth and is formed by the Wolf-Rayet star WR136. Near it (toward the lower left corner) is the elusive planetary nebula Ju 1, discovered by amateur astronomer Dave Jurasevich in 2007.
Integration over 18 hours, 10-minute guided exposures with an Antlia ALP-T 5nm dual-band filter, and 52 1-minute exposures for the stars with an SV260 broadband filter, 150/600 Newtonian telescope with 0.95x corrector, Tecnosky Vision 571C camera, EQ6-R Pro mount, and Pixinsight processing.
NGC 6822, also known as Barnard's Galaxy, is a barred irregular galaxy located in the constellation Sagittarius, about 1.6 million light-years from Earth. It was discovered by American astronomer E. E. Barnard in 1884, making it one of the first galaxies identified outside the Milky Way.

Gyulbudaghian's Nebula(in left- bottom corner) is a little-known variable reflection nebula, similar to Hubble's variable nebula.
t the heart of the Herbig-Haro object lies the variable Herbig AbBe pre-main sequence star PV Cep. This is a newly formed star that is surrounded by a rotating disk of material. At right angles to this disk are two jets of material, streaming away from the star at high speeds. We see the effects of one of these jets on the north side of PV Cep as the stream of material meets the surrounding gas in the interstellar medium. The jet to the south is obscured by a dark nebula (producing an absorption of over 3 magnitudes) (text: www.skyhound.com/observing/archives/oct/GM_1-29.html )

For black and white Wednesday - This is the luminosity channel of the Elephant Trunk Nebula image I posted earlier today. As I wanted to show off the structures of this nebula, this is a starless image, illustrating only the dust clouds that exist there. Isn't it wild that things like this exist?
NGC 7331, also known as Caldwell 30, is an unbarred spiral galaxy about 40 million light-years away in the constellation Pegasus. It was discovered by William Herschel in 1784.
NGC 7331 is the brightest galaxy in the field of a visual grouping known as the NGC 7331 Group of galaxies.
In fact, the other members of the group, NGC 7335, 7336, 7337 and 7340, lie far in the background at distances of approximately 300–350 million light years. [WIKI]

Explanation: Chaotic in appearance, these filaments of shocked, glowing gas break across planet Earth's sky toward the constellation of Cygnus, as part of the Veil Nebula. The Veil Nebula itself is a large supernova remnant, an expanding cloud born of the death explosion of a massive star. Light from the original supernova explosion likely reached Earth over 5,000 years ago. Blasted out in the cataclysmic event, the interstellar shock waves plow through space sweeping up and exciting interstellar material. The glowing filaments are really more like long ripples in a sheet seen almost edge on, remarkably well separated into the glow of ionized hydrogen and sulfur atoms shown in red, and oxygen in blue hues. Also known as the Cygnus Loop, the Veil Nebula now spans nearly 3 degrees or about 6 times the diameter of the full Moon. While that translates to over 70 light-years at its estimated distance of 1,500 light-years, this field of view spans less than one third that distance. Identified as Pickering's Triangle for a director of Harvard College Observatory. (text: apod.nasa.gov/apod/ap150917.html)

Taken from my home in Gérgal, Almería, Spain over 8 nights in January and February 2022.
A wide field view of the Virgo Cluster located in the constellation of Virgo and Coma Berenices. It is estimated that there are at least 1,300 galaxies in this region and possibly as many as 2,000.
On the left of the image is a curved chain of galaxies known as Markarian's Chain which contains near the centre, two interacting galaxies, NGC 4438 and NGC 4438 known as Markarian's Eyes.
This was a project that I added at the end of my nebula imaging sessions due to the Milky Way being very low in the sky in the winter months and I needed a target that was higher in the sky early in the morning. My wide field telescope is not suited to imaging many galaxies so I decided to image a cluster of galaxies instead.
Here's my second attempt at shooting C/2022 E3 (ZTF). This time I was able to capture the "Green Comet" as it passed by NGC5907 seen in the lower center of the frame. NGC5907 is a "knife edge" galaxy (due to its orientation to use) and is approximately 50 Million Light Years from Earth!
This photo is a combination of 28x300" exposures. I used my TS Optics 90mm CF APO refractor telescope with a .8x reducer (430mm focal length.) The camera I used was my ASI 2600MC Pro. For processing I used Pixinsight and processed the star/galaxy image separate from the comet itself.
Thanks for looking!

The magnificent “Hercules Cluster” or NGC6205 in the constellation of Hercules (The Strongman) is one of the best known cluster in the northern hemisphere akin to Alpha Centauri in the south; it is a favorite object to show in star parties as it is easily visible with small telescopes where it appears a fuzzy smudge with smaller scopes and 4 inch or larger instruments will resolve some stars. It is approximately 22,100 light years distant from earth with an apparent magnitude of 5.78 and an angular size of 17 arcminutes. It contains approximately 300,000 to 400,000 stars spread across 145 light years diameter; the stars in the central area are just a few astronomical units (AU) apart.

Elaborazione difficile!
Non immaginavo che con oltre 13h di integrazione elaborare il complesso della nebulosa Velo (trattasi del resto di una supernova esplosa alcuni millenni fa) nella costellazione del Cigno fosse cosi ostico e complicato.
Forse alcuni fattori hanno complicato le cose: acquisizione con la presenza della luna quasi piena, trasparenza del cielo spesso non buona, inquinamento Bortle 6-7.
Probabilmente anche la debole luminosità della nebulosa insieme all'uso di un filtro a Banda-Stretta e ai fattori anzidetti hanno reso insufficienti i 300s di posa.
Ad ogni modo ho cercato di fare del mio meglio, anche se sono ancora principiante con i recenti programmi di elaborazione estetica GraXpert e SIRIL. Molto difficile è stato riuscire ad evidenziare le tenui nebulosità Halfa esterne alle nebulose NGC6960 e NGC6992.
Questa elaborazione ha evedenziato 2-3 criticità ottiche del teleobiettivo Zenit Giove 11-A soprattutto quando si utilizzano più filtri ottici contemporaneamente. Spero di trovare un buon compromesso quando utilizzerò questo obiettivo in futuro.

Difficult processing!
I didn't think that with over 13 hours of integration, processing the complex of the Veil nebula (the remnant of a supernova that exploded a few millennia ago) in the constellation of Cygnus would be so difficult and complicated.
Perhaps some factors complicated things: acquisition with the presence of an almost full moon, often poor transparency of the sky, Bortle 6-7 pollution.
Probably also the weak brightness of the nebula together with the use of a narrow-band filter and the aforementioned factors made the 300s exposure insufficient.
However, I tried to do my best, even though I am still a beginner with the recent aesthetic processing programs GraXpert and SIRIL. It was very difficult to highlight the faint Halfa nebulosities outside the NGC6960 and NGC6992 nebulae.
This processing also highlighted 2-3 optical critical issues of the Zenit Giove 11-A telephoto lens, especially when using multiple optical filters at the same time. I hope to find a good compromise when I use this lens in the future.

🇨🇭 Contempler ce ciel en Suisse était absolument fou ! Bien loin des villes et des villages de la vallée, c'est au sud-est du pays que l'on trouve les endroits les moins touchés par la pollution lumineuse (sans avoir besoin de monter à 3000m d'altitude ).

Ici, nous ne sommes plus très loin des dolomites et la nature du paysage s'en ressent. Ce lieu est tellement paisible, l'herbe y est si verte. Seul les plantes et les fleurs viennent casser cette immense étendue. J'ai trouvé celle-ci au premier plan particulièrement photogénique 🍀. Avec les températures qui chutent beaucoup la nuit, le point de rosée est facilement atteignable et on le remarque par les gouttelettes sur la plante (et aussi un peu sur l'objectif ).

The Rosette Nebula (C49) in SHO.
Also known as the "Skull Nebula" and Caldwell 49, the Rosette Nebula is a large HII region of bright gas and filaments of dark dust, located in the constellation of Monoceros. The open cluster NGC 2244 (discovered by John Flamsteed in 1690) is associated with this region - the stars of which were formed within this molecular cloud. Located 5000 light years away, and measuring 65 light years in diameter, the Rosette Nebula is very large with an angular diameter of about 1.3 degrees - almost 3 times the diameter of the full moon. This object is so large that there are at least fie NGC listing numbers associated with it (NGC 2237, NGC 2238, NGC 2239, NGC 2244, & NGC 2246). It takes the form large gaseous "donut" and often compared to an architectural rosette - thus its name. This area is a rich star forming complex with over 2500 hot new stars which excite the gas and cause its glow. The stellar winds from these stars exert pressure on interstellar clouds and the compression leads to ongoing star forming activity in the region.
This object is a very tough one for me to shoot. By time we reach astrophotographic darkness, it is located due south near the meridian. This gives me a about 1.5 hours before it moves into some trees that block my view. The fact that the moon was out also did not help. Given how large the Rosette is, I really needed to shoot this with a wide field scope - but a wide field would end up hitting the trees sooner and shorted my shooting time. So I ended up using my AP130mm scope which has a focal length of 1050mm - there is no way I would end up fitting the entire object into it's field of view, so I framed this to focus on the center of the "donut hole" for a more close-in study of the region. So the conditions were NOT optimal, but when you live in Rochester NY, the 18% Gray capital of the Universe, you shoot when you get some clear skies - regardless!
So over a period of 3 nights, I attempted to capture 5 minute subs with my mono camera and narrowband filters. I really did not have high hopes for this image. Once I had three nights of data, I pulled subs in and inspected them with Blink and saw something strange - many of the later subs from each evening had strange looking stars - closer inspection showed a single line protruding from many starts. It looked like a diffraction spike, except there was only one spike! I finally realized that I was hitting the tree line sooner that I thought and the tree branches, denuded of leaves, seemed to be causing the star distortions!
So I removed the worse subs that I had and then processed them. If I had taken all of the effective subs out, I would have way too few to get a decent image, so I did leave in some that were partially effected. To my surprise the image came out better than I expected. If you look really close, you could see what looks like some star elongations resulting including some subs that showed a little of this effect. I did some post processing to try and correct for this and I was able to reduce the effect for the most part.
So not a perfect image, but given the capture challenge, I was somewhat surprised and happy with the result I did get.

A quick side project in the middle of a few different dusty objects I have been imaging. VdB 131/132 (left and middle blue reflections) in Cygnus. A cool little region surround by gobs of Ha & Oiii emissions. I found processing this area to be quite enjoyable as all the nebulosity is so bright. One day perhaps, I will image this much closer up with a larger scope.

An HDR version of M42 Orion Nebula and The Running Man Nebula.
Imaged from my home in Gergal, Spain in November 2024.
This was to test the performance of a new iOptron CEM 26EC portable mount for my William Optics GT81 telescope. The ASI 1600MC Pro Cool camera was on loan from the Los Coloraos complex while I wait for a new mono image rig to be assembled. The images were taken without any filters at all.
I also took some narrow band data but after experimenting with the data, I decided I preferred the natural colours of the nebula.
Thank you for taking a look
LBN 777 aka the "Baby Eagle" - a super cool little dark nebula in the vast Taurus Molecular Cloud. I had been eyeing this target for a while but until now, could never put in the integration time it demands.
One of my favorite parts of this image is the bow shock surrounding the head of the eagle. There are also a ton of small background galaxies in this region.

The Crescent Nebula is an emission nebula in the constellation Cygnus, about 5000 light-years away from Earth. It was discovered by William Herschel in 1792.
I've been imaging the Crescent Nebula area over the last week when I got clear nights. I managed to get 5 nights with an average of 4+ hours each night, for an integration time over 20 hours. This is by far the longest integration time I've ever acquired. I wanted to experiment with longer integration times with an OSC camera (ASI2600MC Pro).
I used the FLT132 with the FLAT8 reducer (0.72x) to get a slightly wider field of view; it just about includes the Soap Bubble at the top left(ish) corner. I also used a combination of narrowband filters (Optolong L-Ultimate 3nm Ha & Oiii, IDAS NBZ and Antlia ALP-T 5nm Ha & Oiii) as well as a more broadband filter, Antlia Triband RGB Ultra. I think the combination of all the filters provides a more balanced set of colours, including a decent amount of Oiii detail in the Crescent Nebula.
Processed in PixInsight and Affinity Photo 2.

This reflection nebula is located in the Carina constellation. Astronomers believe that the dust in the nebula is being emitted by a red giant, which also illuminates the object. This is a rare example of a star in its final stages before becoming a white dwarf.

Remote Data from Deepskywest El Sauce Observatory, Chile.
This year, ESA's ground station boffins are planning to deploy a new cryogenically cooled "antenna feed" – a gizmo used to transmit and receive deep space signals – on the Agency's three deep-space antennas.
The ground stations routinely communicate with missions like BepiColombo – heading to Mercury, Gaia – surveying stars in our Galaxy, and ESA's two spacecraft at the Red Planet, Mars Express and the ExoMars Trace Gas Orbiter.
ESA’s 35-metre antennas receive data from working spacecraft, in what’s called a ‘downlink’. As the Agency prepares to launch new missions deeper into our Solar System in the next few years, including Juice to Jupiter and the ExoMars Rover, as well as missions designed to generate large quantities of data, such as the future Sun-watching Lagrange mission, use of the stations' downlink capacity is set to grow significantly.
This means the stations have to 'up their game', and the new antenna feed is expected improve data return by 40% at the high frequencies used for spacecraft command and control. The feed must be cooled to just 10 K (just 10 degrees from absolute zero, about -263 C) for normal operation.
"While receiving extremely faint signals, the new feed should be capable of transmitting command signals to spacecraft at very high power of more than 25 kilowatts", says ESA ground station engineer Stéphane Halté.
"This is similar to the amount of power transmitted by 25 000 mobile phones switched on simultaneously."
The prototype antenna feed was mounted on NASA’s Deep Space Station 13 (pictured), at NASA's High Power Transmitter Test facility, in Goldstone, California. It was tested in December 2018 with the assistance of experts from the NASA Jet Propulsion Lab's Deep Space Network.
Testing successful, this ESA/NASA cooperation has cleared the way for the new technology to be rolled out at across ESA’s deep space ground stations, part of the Estrack network, within this year.

M104 or The Sombrero Galaxy is a spiral galaxy in the constellation borders of Virgo and Corvus. The Sombrero Galaxy is about 29.35 million light years from our galaxy. Looking at this photo of M104 it really illustrates the vastness of space. If you look closely at the background, you can see a few faint galaxies off in the distance (cigar-like and circular objects).
Thanks for viewing and clear skies everyone!
Tech Details:
What started off as a quick hour and a half acquisition of data turned into a 7+ hour project. Initially collected the RGB as binned 2x2, with 300sec exposures but changed my mind part way through and only collected binned 1x1 (600sec exposures). Luminance was also captured using 600sec exposures. I’m still learning the ins and outs of astrophotography made a few mistakes along the way but I’m pretty happy with the result.
Exposures, Integration Time and Filters, and Software:
Luminance: 3.2 hrs total
Red: 1.4 hrs total
Green: 1.4 hrs total
Blue: 1.2 hrs total
Total integration: 7.2 hrs
Software: AstroPixel Processor, Pixinsight Photoshop,
Iris Nebula is dramatic reflection nebula in the constellation Cepheus.
With plenty of dark interstellar dust is illuminated by a central hot star named SAO 19158 which is 10 times the mass of our sun.
It lies 1,300 light-years away and is six light-years across.
It was integrated only 15 hours, 50% best frames of the total valid frames taken between May and June of 2019.
PD: I am glad to check my improvements when I compare to this other capture from three years ago. :D
