First attempt at this. I opted for the Hubble Pallette for processing as it seems to bring out the spookiness of this nebula a little better.
his image of the open star cluster NGC 7380, also known as the Wizard Nebula, is a mosaic of images from the WISE mission spanning an area on the sky of about 5 times the size of the full moon. NGC 7380 is located in the constellation Cepheus about 7,000 light-years from Earth within the Milky Way Galaxy. The star cluster is embedded in a nebula, which spans some 110 light-years. The stars of NGC 7380 have emerged from this star-forming region in the last 5 million years or so, making it a relatively young cluster.

I captured this image on Jan 2nd 2023 over the course of around an hour, it was a bit of a suck it and see experiment really as I had my mini rig out to image the Moon, but decided I would try some unguided short captures and see what I could do with the resulting subs.
There is some degree of rotation as expected and I have cropped the final image, the walking noise does visibly rotate about the field of view when it’s stretched a lot.
However APP along with the calibration frames hasn’t done a terrible job of dealing with it considering it’s just a grab and go AZ capture with no guiding, the 72EDF’s sharp optics have helped reveal some fair details in the dust and darkness.
Captured with SharpCap 4 Pro.

Last Super Blue Moon until 2037.
"Why a blue supermoon? That’s an entirely different story. A blue moon is not actually blue at all; that is simply the nickname that’s given to the second full moon that occurs in a month, and the phenomenon does not happen often; just 3% of full moons are also blue moons, according to NASA. The rarest shy show of all occurred last night—and will continue on Sept. 1 — when a combination of full moon plus super moon plus blue moon appeared in the sky. If you miss it, you’ll have to wait a while for the next one: according to NASA, the next blue supermoon will not occur until 2037. Typically, blue supermoons occur only once every 20 years or so."

Taken from Oxfordshire, UK on the afternoon of 3rd April 2023. Because it was mid-afternoon when I started imaging, conditions were not great, but there was some nice activity visible on the Sun, and sunspot group AR13270 was looking lovely in H-alpha.
Taken with a Coronado PST and ASI120MC camera fitted with a 2x Barlow. A 1,000 frame video was taken using SharpCap, then the best 30% or 50% were stacked depending on the quality graph.
Processing workflow:
RGB alignment in Registax 6
Sharpening using Focus Magic
Remove all colour + processing in Lightroom
False colour added back in using Photoshop CS2
Final tweaks & denoise using Fast Stone Image Viewer
After I had imaged the two active regions visible on today's Sun, I upped the exposure level and checked around the limb for any other prominences. I was really happy when I spotted this lovely looping prominence on the SE limb, but once I'd stacked and processed the image, I noticed some other fainter proms a bit further up.

The Heart Nebula, IC 1805, Sharpless 2-190, lies 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 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.

Technical Information
This image was taken with a William Optics Zenithstar 81 APO Doublet Refractor on an iOptron CEM25P mount. This telescope is a very compact unit and has optical elements made of FPL53 glass and is actually considerably sharper than some of my larger telescopes. The main imaging camera, attached to the prime focus of the telescope was a ZWO ASI294MC Pro cooled camera which was cooled to -5C. Exposures were 30 at 180 seconds each, and the gain was set to 120. Auto guiding was done using a William Optics 50mm guide scope with a 200mm FL. Attached to the guide scope was a ZWO ASI290MC camera which was connected to PHD2 autoguiding software. Capturing was done with Astrophotography Tool (APT) software and post processed with Pixinsight software with finishing touches put in using Adobe Photoshop Creative Cloud. Polar Alignment for the evening was done using SharpCap software.
The odd gap in the clouds mid afternoon allowed me to grab a couple of solar scans using my Evostar 72ED and Sol'Ex SHG with QHY5III 178M. 16x sidereal speed used on CEM60 to force the scans whilst recording SER files in Sharpcap, Single scans,no processing apart from resize and flipping horizontally (north towards top right hand corner) Whilst recording in the Calcium K line the scope was reduced to 40mm f/10.5.
Taken from Oxfordshire, UK with a William Optics 70mm refractor + ASI120MC camera fitted with a 3x Barlow. The mount was my Skywatcher AZ GTi on a tripod. I had to use my portable set up because the Moon was too low to get above the trees from my permanent pier or from the observatory shed.
I grabbed the telescope because I wanted to capture the Lunar X and V on the 44% Waxing Crescent Moon before the Moon set. I had to dodge endless patches of cloud which were making my life miserable! Given the conditions I'm really really happy with the photos I got!
I captured a 1,000 frame video using SharpCap. I stacked the best 50% of those frames in Autostakkert! 3, then processed the images in Lightroom and Fast Stone Image Viewer.
The M13 globular cluster in Hercules is a summer favorite. With 300,000 stars some 25,000 light years away, it has an apparent magnitude of 5.8 placing it in a sweet spot for urban backyard astronomers -- we'll never make it out with the naked eye but it shows well in a small telescope, and it makes a beautiful target for beginning and intermediate astrophotographers. In this instance I'm exploring the capabilities of a monochrome CMOS camera and basic RGB filter set; the longest single exposure used to build this image was 2 seconds.

The Double Cluster (also known as Caldwell 14) consists of the open clusters NGC 869 and NGC 884 (often designated h Persei and χ Persei, respectively), which are close together in the constellation Perseus. Both visible with the naked eye, NGC 869 and NGC 884 lie at a distance of 7,500 light years.
NGC 869 has a mass of 3,700 solar masses and NGC 884 weighs in at 2,800 solar masses; however, later research has shown both clusters are surrounded with a very extensive halo of stars, with a total mass for the complex of at least 20,000 solar masses. Based on their individual stars, the clusters are relatively young, both 12.8 million years old. In comparison, the Pleiades have an estimated age ranging from 75 million years to 150 million years.
There are more than 300 blue-white super-giant stars in each of the clusters. The clusters are also blueshifted, with NGC 869 approaching Earth at a speed of 39 km/s (24 mi/s) and NGC 884 approaching at a similar speed of 38 km/s (24 mi/s). Their hottest main sequence stars are of spectral type B0. NGC 884 includes five prominent red supergiant stars, all variable and all around 8th magnitude: RS Persei, AD Persei, FZ Persei, V403 Persei, and V439 Persei. (Wikipedia.org)

NGC 6888
(nota anche come Nebulosa Crescente o con la sigla C27) è una nebulosa diffusa visibile nella parte meridionale della costellazione del Cigno.
Osservazione
Si individua 2,5 gradi a sud-ovest della stella γ Cygni, subito ad ovest di un ricchissimo campo stellare, in cui sono inclusi oggetti come M29 e IC 4996.
La parte più intensa della nebulosa si trova nella parte occidentale, e forma un arco esteso più in declinazione che in ascensione retta; questa caratteristica ha fatto sì che la nebulosa fosse chiamata crescente, poiché presenta la "gobba" a ponente, come la Luna in fase crescente.
Per individuarla occorre un telescopio, anche se di piccola apertura; un binocolo consente di intravederla appena in condizioni di cielo nitido.
Caratteristiche
Si tratta di una tipica bolla di vento stellare generata da una massiccia stella di Wolf-Rayet (la HD 192163), che si trova al suo interno; questa stella sarebbe anche la responsabile della nebulosa, che costituirebbe il materiale degli strati più esterni della stella espulsi.
Questo vento è andato a collidere col materiale espulso dalla stella durante il raggiungimento dello stadio di gigante rossa, fra 250.000 e 400.000 anni fa, energizzandolo.
Il risultato è un guscio gassoso e la presenza di due onde d'urto, che hanno poi interagito col denso mezzo interstellare circostante.
In passato si è anche ritenuto che si fosse trattato di un resto di supernova, la cui stella progenitrice faceva parte del sistema di HD 192163.
La nebulosa si estende nello spazio per una dimensione di circa 16 anni luce.
APPROFONDIMENTO: Stella di Wolf-Rayet
Le stelle di Wolf-Rayet (abbreviazione: stelle W.R.) sono stelle massicce (almeno 20M⊙ alla nascita) molto evolute, e molto calde rispetto alla media. Spesso sono stelle eruttive. Il colore è bianco-azzurro, e corrisponde a temperature superficiali comprese fra 30000K e 200000K.
Si tratta di stelle molto luminose, con una luminosità compresa fra centinaia di migliaia e milioni di volte quella del Sole, sebbene nella banda del visibile non siano eccezionalmente luminose, in quanto la maggior parte della radiazione viene emessa sotto forma di raggi ultravioletti e perfino di raggi X molli.
Stelle di questo tipo sono molto rare: ne sono conosciute poche centinaia in tutto il Gruppo Locale. La maggior parte di esse è stata scoperta negli anni 2000, in seguito a estese indagini fotometriche e spettroscopiche dedicate alla ricerca di tali oggetti nel piano galattico. A causa delle loro marcate linee di emissione, le WR sono individuabili anche in altre galassie.
Perdono massa a ritmi elevati per mezzo di venti stellari molto intensi e veloci (fino a oltre 2000km/s).
Le Wolf-Rayet perdono generalmente 10−5M☉ ogni anno (un centomillesimo di volte la massa del Sole). Una tale perdita di massa causa l'espulsione del guscio di idrogeno che avvolge la stella scoprendo il nucleo di elio, che ha temperature molto elevate.
Le stelle visibili a occhio nudo γ Velorum e θ Muscae sono Wolf-Rayet, così come lo è la stella più massiccia attualmente conosciuta, R136a1 nella Nebulosa Tarantola.
Nebulosa Bolla di Sapone
La Nebulosa Bolla di Sapone, PN Ju 1 (nota anche come PN G075.5+01.7) è una nebulosa planetaria nella costellazione del Cigno, vicino alla Nebulosa NGC 6888.
La nebulosa deriva il suo nome dalla sua forma sferica simmetrica che ricorda una bolla di sapone.
SCOPERTA:
Fu scoperta dall'astronomo amatoriale Dave Jurasevich utilizzando un telescopio rifrattore Astro-Physics da 160mm con il quale riprese la nebulosa il 19 giugno 2007 e il 6 luglio 2008.
La nebulosa fu poi notata indipendentemente e segnalata all'Unione Astronomica Internazionale da Keith B. Quattrocchi e Mel Helm che ripresero PN G75.5+1.7 il 17 luglio 2008.
La nebulosa misura 260″ di diametro angolare con una stella centrale che ha una magnitudine della banda J di 19,45.
A causa della debolezza della nebulosa e del fatto che è incastonata in una nebulosa diffusa, la nebulosa diffusa è molto difficile da "catturare" in fotografia.
APPROFONDIMENTO: Nebulosa planetaria
Una nebulosa planetaria è un tipo di nebulosa a emissione costituita da un guscio luminoso e in espansione di gas ionizzato espulso da stelle giganti rosse verso la fine della loro vita.
Il termine "nebulosa planetaria" è un termine improprio perché non sono correlate ai pianeti. Il termine deriva dalla forma rotonda simile a quella di un pianeta di queste nebulose osservate dagli astronomi attraverso i primi telescopi. Il primo utilizzo potrebbe essere avvenuto durante gli anni '80 del Settecento con l'astronomo inglese William Herschel che descrisse queste nebulose come simili a pianeti; tuttavia, già nel gennaio 1779, l'astronomo francese Antoine Darquier de Pellepoix descrisse nelle sue osservazioni della Nebulosa Anello, "molto debole ma perfettamente delineata; è grande quanto Giove e assomiglia a un pianeta che svanisce".
Sebbene l'interpretazione moderna sia diversa, il vecchio termine è ancora utilizzato.
Tutte le nebulose planetarie si formano alla fine della vita di una stella di massa intermedia, circa 1-8 masse solari. Ci si aspetta che il Sole formi una nebulosa planetaria alla fine del suo ciclo di vita.
Sono fenomeni di durata relativamente breve, che durano forse alcune decine di millenni, rispetto alle fasi notevolmente più lunghe dell'evoluzione stellare.

The Eagle Nebula some 7000 light years distant is a star forming region in the constellation Serpens. This emission nebula includes the "Pillars of Creation," an early triumph of the Hubble Space Telescope program. My image emphasizes the reddish glow of hydrogen dust. Because M16 is relatively low in the sky It took me a full month to get two good nights of imaging during the 90 minute window between the time the nebula clears my roof and descends into the trees.

Around 60% of the images were shot at 70%+ rel humidity, I'd like to gather equivalent at lower humidy to compare results as the first 45 images were much clearer at lower humidity even at 99% moon.
Messier 45 Pleiades Star Cluster. Also known as the Seven Sisters, are an open star cluster containing middle-aged, hot B-type stars in the north-west of the constellation Taurus. It is among the star clusters nearest to Earth and is the cluster most obvious to the naked eye in the night sky.
The cluster is dominated by hot blue and luminous stars that have formed within the last 100 million years. Reflection nebulae around the brightest stars were once thought to be left over material from the formation of the cluster, but are now considered likely to be an unrelated dust cloud in the interstellar medium through which the stars are currently passing.

Technical Information for This Image
The telescope used was a Explore Scientific ED80 APO Refractor on a Celestron Advanced VX mount. This telescope is a very compact unit and is easy to carry out to my dark site and set up. The main imaging camera, attached to the prime focus of the telescope was a ZWO ASI294MC Pro cooled camera which was cooled to -5C. The exposures were 25x120 seconds and 60x60 seconds, and the gain was set to 120. No darks, flats or bias calibration frames were used. Auto guiding was done using a Orion Mini-Guidescope 50mm refractor attached to a ZWO ASI183MC camera which was connected to PHD2 autoguiding software. Capturing was done with Astrophotography Tool (APT) software and post processed with Pixinsight software with finishing touches put in using Adobe Photoshop Creative Cloud. Polar Alignment for the evening was done using SharpCap software.

Captured with SharpCap planetary tracking and livestacking, processed with AstroSurface and PixInsight.
For reference the calculated focal length is 5900 mm, a tad less than the native 1400mm X 5x (scope focal length and PowerMate factor varies with camera position).

First light for my new ZWOASI120MC cmos camera which I got for Christmas. We've had the mono version for years and I loved it, but it stopped running on my Windows 8 laptop and nothing we tried would stop it from crashing each time I plugged it in. So I haven't used it for a very long time and it's in fact now used as a guide camera in our observatory set up! I got the colour version for Christmas but hadn't even plugged it in because I assumed I would have the same issues that I had with the older camera. Today I just figured I'd give it a try and to my astonishment it worked!
Taken from Oxfordshire, UK with a William Optics 70mm refractor, and the ASI120MC camera with a 2x Barlow attached. The whole assembly was on an EQ5 Pro mount on a permanent pier.
2,000 frame video shot using SharpCap, the best % frames were stacked using Autostakkert! 3 Beta and wavelets adjusted in Registax 6. The image was then processed in Lightroom, Fast Stone Image Viewer and Focus Magic.
I decided to take advantage of the new moon, drag my telescope, and do some astrophotography last night...even with the time change and losing an hour of sleep. I'd say the bit of sleepiness today was worth it to get back into Astro and get this shot of my first time imaging this nebula!
The Rosette Nebula (NGC 2237) is 65 light-years across and 5,500 light-years away from Earth. It is visible in the sky between the constellations Gemini and Orion, in the head of the constellation Monoceros.

I polar aligned my mount using SharpCap Pro. My Sony a7SIII and adapted Nikkor 500mm f/4 P AI-S were mounted on an ADM vixen rail and secured to the SkyWatcher EQ6-R mount. The guide scope/camera was attached to the camera's hot shoe. I used PHD2 to autogude during the imaging session. DeepSkyStacker was used to combine all frames, and the outputted TIFF file was brought into PixInsight using: STF, Cropping, Dynamic Background Extraction, BlurXTerminator, plate solving, color correction, NoiseXTerminator and then the DSO was separated from the stars, and both files processed and stretched separately and then recombined using PixelMath. That file was brought into Lightroom for Metadata and EXIF tags, light post-processing, and cropping to the final image.
