Messier 25, is an open cluster of stars in the southern constellation of Sagittarius. The first recorded observation of this cluster was made by Philippe Loys de Chéseaux in 1745 and it was included in Charles Messier's list of nebulous objects in 1764. M25 is at a distance of about 2,000 light-years away from Earth.

Still pretty cloudy at night, but consoling myself with the discovery of data I had forgotten about, four hours on the Heart and Soul Nebulae, IC1805 and IC1848 respectively. They are emission nebulae, star forming regions in the Perseus Arm of the Milky Way Galaxy, located roughly 7000 light years away, the Heart is about 13% further away than the Soul.
This image is a 4 hour calibrated integration of 180s sub-exposures taken over three nights at the beginning of October. I imaged these around the same time last year with the same setup but I think this result is a marked improvement.

Dark nebulae are large clouds of gas and dust and among the densest in the universe. They're so dense that they completely absorb all visible light — including nearby stars. Dark nebulae are sometimes referred to as 'holes in the sky' but in reality, there are stars forming inside their dense clouds.

My first attempt at a mosaic (where you create several images and stitch them together to get a larger field of view in one larger image). This is a mosaic of four 40 minute calibrated integrations of 2 minute exposures. Each image is about 12 degrees on a side creating a final image that reveals most of the constellation Cygnus, The Swan. Many well known deep sky objects are visible including the North American Nebula , The Pelican Nebula, the Veil Supernova Remnant, all the Nebulosity around Sadr including the Crescent Nebula and the Tulip Nebula, and several more objects...
The exposures were taken with a Nikkor 50mm Lens working at f/2.8, attached to a ZWO ASI533MC Pro Camera. An Optolong L-Ultimate narrowband filter was also used, which goes a long way to combat the Bortle 8 light pollution of Toronto. Everything was mounted on a ZWO AM5 and controlled by the ASI Air Plus. The exposures were guided. Images were processed in SIRIL and PixInsight
I'm really pleased with this as a first attempt, it certainly can be tweaked and processes further - when I have time...

Description: I developed this image of the North American Nebula NGC 700 from 60x300s subs or 5.0 hours of total exposure time. I used the Optolong L-eXtreme Dual Bandpass Light Pollution Filter. It has two 7nm pass bands centered on the H-alpha and OIII wavelengths. With a one-shot color (OSC) camera and an L-eXtreme filter combination the red signal from the H-alpha tends to dominate. In the nonlinear postprocessing phase I applied Histogram Transformation, Local Histogram Equalization and Curves Transformation in small doses in multiple passes.

La Nebulosa Nord America (anche nota con le sigle NGC 7000 e C 20) è una nebulosa a emissione visibile nella costellazione del Cigno, vicino a Deneb (la coda del cigno e la sua stella più brillante). La forma della nebulosa disegna il continente nordamericano, soprattutto la costa est, tra il Golfo del Messico e la Florida.
La scoperta della Nebulosa Nord America è attribuita all'astronomo William Herschel. Essa costituisce assieme alla vicina Nebulosa Pellicano un unico complesso nebuloso, situato a circa 1960 anni luce, in cui è attiva la formazione stellare, come è testimoniato dalla presenza di diversi oggetti stellari giovani e oggetti HH; questi fenomeni riguardano principalmente stelle di piccola e media massa.

This colorful skyscape spans about four full moons (2 degrees) across nebula rich starfields along the plane of our Milky Way Galaxy in the royal northern constellation Cepheus. Near the edge of the region's massive molecular cloud some 2,400 light-years away, bright reddish emission region Sharpless (Sh) 155 lies at the center, also known as the Cave Nebula. About 10 light-years across the cosmic cave's bright rims of gas are ionized by ultraviolet light from hot young stars. Dusty blue reflection nebulae also abound on the interstellar canvas cut by dense obscuring clouds of dust. The long core of the Lynds Dark Nebula (LDN) 1210 anchors the scene at right. Astronomical explorations have revealed other dramatic signs of star formation, including the bright red fleck of Herbig-Haro (HH) 168. Directly below the bright Cave Nebula, the Herbig-Haro object emission is generated by energetic jets from a newborn star. [Text adapted

Captured from my backyard Observatory in Fremont Michigan over 3 nights July 2016 using the new QHY16200 Mono CCD, an exciting new feature of the QHY16200 is the development of the 7 Position Filter Wheel which will be fitted to my sample, time and weather permitting I hope to be able to capture this beautiful object with other Narrowband filters.
Lying at a distance of approximately 1470 Light Years from us The Eastern Veil Nebula or otherwise known as NGC 6992 is part of the much larger Cygnus Loop which is a supernova remnant.
The expanding cloud of diverse elements created in the most powerful of explosions; a supernova.
As a Massive star nears the end of its life, it runs out of hydrogen fuel and begins fusing helium. After exhausting its supply of helium it begins to fuse heavier elements until finally, the star's core can no longer exert enough outward pressure and it collapses. A shock wave rebounds through the star so fierce that the star is shredded and leaves behind a small but extremely dense body; either a neutron star or a black hole.

NGC 4565 the Needle Galaxy
NGC 4565 (also known as the Needle Galaxy or Caldwell 38) is an edge-on spiral galaxy about 30 to 50 million light-years away in the constellation Coma Berenices. It lies close to the North Galactic Pole and has a visual magnitude of approximately 10. It is known as the Needle Galaxy for its narrow profile. First recorded in 1785 by William Herschel, it is a prominent example of an edge-on spiral galaxy.
NGC 4565 is a giant spiral galaxy more luminous than the Andromeda Galaxy. Much speculation exists in literature as to the nature of the central bulge. In the absence of clear-cut dynamical data on the motions of stars in the bulge, the photometric data alone cannot adjudge among various options put forth. However, its exponential shape suggested that it is a barred spiral galaxy. Studies with the help of the Spitzer Space Telescope not only confirmed the presence of a central bar but also showed a pseudobulge within it as well as an inner ring.
NGC 4565 has at least two satellite galaxies, one of which is interacting with it. It has a population of roughly 240 globular clusters, more than the Milky Way.
This edge-on galaxy exhibits a slightly warped and extended disk under deep optical surveys- likely due to ongoing interactions with neighboring satellite galaxies or other galaxies in the Coma I group. (Wikipedia.org)

Markarian's Chain is name for a string of galaxies in the Virgo area. They are about 50-55 million light-years away. The 2 interacting galaxies in the middle (NGC 4438, NGC 4435) are known as the "The Eyes", and they are about 100,000 light-years apart.
They are believed to have come within about 16,000 light years of each other some 100 million years ago, which resulted in gravitational tides from the encounter ripping away material – stars, gas and dust – from NGC 4438 and removing most of the dust and gas from NGC 4435 and reducing its mass in the process. The bigger NGC 4438 was able to hold on to a good portion of the material torn out in the encounter, while much of the material from NGC 4435 was lost.
19th century observer L. S. Copeland named the pair the Eyes Galaxies. In medium-sized telescopes, the galaxies’ bright oval cores look like a pair of eyes glowing in the dark.

The famous and fabulous Heart Nebula in Cassiopeia dominates this frame but my target was actually the very faint supernova remnant (SNR) HB3 visible as wisply blue and red tendrils in the lower right quadrant of the frame. This widefield shot was taken with a William Optics Redcat51 telescope and an ASI2600MC Pro camera. It is an integration of over 20 hours data shot with an Optolong L-eXtreme filter and a further 6 hours with a UV-IR block. The SNR is much fainter than I had hoped and the low altitude above the Northern horizon reached by these nebulae from my low latitude location in Thailand may be a factor. All post-processing was carried out in PixInsight.
Taken from my Bortle 7 skies in Sydney Australia. Taken with Espirit 150 refractor, ASI2600MC camera and Optolong filter. Image consists of 72 X 3 minutes livestacked and calibrated on the fly in SharpCap Pro.

I have photographed the Heart Nebula before, and was always curious and interested in the little appendix in the corner. It can easily be overlooked when looking at the much larger and impressive details of the Heart Nebula (see flic.kr/p/2qgwVE8). This time, I decided to spend some quality time imaging NGC896; I love the intricate patterns of dark dust clouds interspersed with brighter regions full of young stars.
In total, I've managed to acquire 27 hours of narrowband data, with both the Optolong L-Ultimate (3nm Ha & Oiii) and with the Antlia ALP-T 5nm Ha & Oiii filters. I used the ZWO ASI2600MC Pro camera, on an AM5 mount with ASIAir Plus. Processed with PixInsight + Affinity Photo 2.
This is the Starless SHO palette colours. Please see the HOO with stars here: flic.kr/p/2qg6dbf

I hope you like it and perhaps be inspired to spend some time imaging and/or admiring this somewhat overlooked but beautiful nebula.
Thanks for looking.

===== From Wikipedia ====
The Fish Head Nebula, or the Northern Bear Nebula, is part of a large star forming system of gas and dust located along the Perseus spiral arm of the Milky Way. The nebula is located in the Constellation Cassiopeia, approximately 6,000 light-years from Earth and is adjacent to the much larger Heart Nebula. The brighter region of the nebula is designated NGC 896 and is the home to many young and large stars. These stars radiate high amounts of ultraviolet light. This UV radiation excites the surrounding gas and causes it to shine at a high brightness.
Die nächste Nebelformation im Sternbild Schwan; der Nordamerika- & der Pelikannebel. Heute aber etwas zur Fototechnik.
Die Aufnahme zeigt ein Halpha-Rot, Grün, OIII-Blau Komposit. Hierzu wurden RGB-Aufnahmen und Duo-Schmalband gemischt. Effekt ist die Verstärkung feiner Nebelstrukturen sowie kleine feine Sterne. Hoffe es gefällt euch?
The next huge area of nebulosity in the constellation Cygnus; the Northamerica & Pelicane nebula. Today a few words to the photography method.
This capture shows an Halpha-Red, Green, OIII-Blue composite. For this RGB captures were mixed with duonarrowband captures. This enhances areas of dim nebulosity and caused small pinpoint stars.

La nébuleuse du cœur (IC 1805) et la nébuleuse de l'âme (IC 1848)
Astrométrie : nova.astrometry.net/annotated_full/8326464
Ces deux nébuleuses se trouvent dans la constellation de Cassiopée, le W fait d'étoiles au nord.
La nébuleuse du coeur, à droite sur la photo est une nébuleuse en émission (ses gaz échauffés par les étoiles voisines, en l'occurrence celles de l'amas Melotte 15 qui se situe au cœur de cette nébuleuse (et que l'on voit sur la photo). Elle se situe à 6500 années lumières (AL) de nous (sa lumière est partie à l'époque du prédynastique ancien en Egypte) et mesure 200 AL de diamètre. Sa couleur rouge vient de l'hydrogène, mais elle a aussi à l'intérieur de sa couronne une coloration bleue (peu distinguable sur la photo ; je ferai un traitement adapté permettant de faire ressortir ces couleurs) venant de l'oxygène. Sa forme en couronne (en coeur) évidée en son centre est due aux vents stellaires repoussant les gaz vers l'extérieur. L'amas ouvert en son centre, Melotte 15, contient quelques très grosses étoiles faisant plus de 50 fois la masse du soleil.
La nébuleuse de l'âme se trouve à la même distance et a une dimension d'environ 200x100 AL. C'est aussi une nébuleuse en émission qui contient également un amas ouvert en son centre.
Ces deux objets peuvent être observés aux jumelles.
Côté technique, elle résulte de 90 poses seulement car la constellation a fini par rejoindre le toit de mon garage, me faisant perdre 36 poses (avec un bout de toit de garage). Chaque pose est de 60 sec (donc un cumul d'1h30) faite à 1600 iso avec un Canon 1200 D dp + filtre Optolong L-Enhance + objectif Samyang 135 f/1.4 @f/2.8. J'ai également fait 156/50/42 DOF (oui ... 156, parce que je suis allé me coucher laissant l'appareil faire ses darks ... au moins ils sont propres !). Le suivi était assuré par une monture Skywatcher Star Adventurer.
Pour le traitement, j'ai utilise Siril (prétraitement et traitements manuels) + Gimp.
La photo a un peu de bruit car elle manque de poses. Mais c'est seulement le début de la saison pour ces deux nébuleuses qui vont être de plus en plus faciles à capter dans le ciel, donc je referai des poses dessus.
While imaging and processing the The Tulip nebula, I was surprised to see I also captured the shock wave being produced from Cygnus X-1. It is the site of one of the first suspected black holes. Over the years the location of this X-ray source became more accurately determined. The X-ray source was found to lie very close to the position of a 9th magnitude star called HDE 226868. This star is a large blue supergiant, and its companion – the more compact of the two objects in the system – is thought to be between 20 and 35 solar masses. Since the largest possible mass of a neutron star can not exceed three solar masses, the compact object which is unseen, is almost certainly a black hole. These two objects share an orbital periodicity of 5.6 days.

Messier 15 is a globular cluster in the constellation Pegasus. At an estimated 12.0 billion years old, it is one of the oldest known globular clusters. M15 is about 33,600 light-years from Earth, and it has a total luminosity of 360,000 times that of the Sun. Messier 15 is one of the most densely packed globulars known in the Milky Way galaxy. Its core has undergone a contraction known as "core collapse" and it has a central density cusp with an enormous number of stars surrounding what may be a central black hole.

Back in May I have published a photo of M101, the Pinwheel Galaxy (see here flic.kr/p/2nknGGe), but lately the new developments on processing, as well as the lack of new data, made me decide to reprocess the same data. I am really happy as it turned out much better than before, IMHO. I hope you enjoy.

Jupiter and Ganymede, photographed from my backyard in Long Beach, CA
Autostakkert did a better job of tracking Ganymede when it was closer to the disk of Jupiter. I was able to get some surface detail on the Galilean moon in this image.
30 s SER files were taken with a ZWO ASI120MM camera through Optolong CCD RGB filters on a Celestron Edge HD 925 telescope using FireCapture. The top 75% of frames went into 7 stacks of each color filter. These stacks were made in AutoStakkert, then sharpened in PixInsight. Stacks were combined and derotated in WinJUPOS, and the resulting R, G, and B images were combined in WinJUPOS to make a de-rotated single color image. Color balancing in Registax, then final touches in Photoshop.
Autostakkert didn't seem to pick up Ganymede in these images, thus rendering it featureless.

This is only seen in the Southern hemisphere as this is right next to the Large Magellanic Cloud which you can see top most of the photo the white area. Which I will have to wait to get higher in the sky away from the City lights. First night I tried to get this the weather did not help the photos so I had to delete them all and start again. A very busy place in the sky.

This started life as a panorama on the long side to make a square but nina gave me the Perfect panorama on the short side.
I was struck with the face you can see as the dot on the left side quite amazing. With a lot of technical looking into the image header and finding out the RA and DEC values we were able to find out the head is GUM 85. we had to put those values in a search engine for space.

Questa bella e interessante nebulosa nella costellazione dell'Auriga si è dimostrata abbastanza debole e di difficile elaborazione. Infatti speravo di aumentare l'integrazione per migliorarne il segnale, ma dai primi giorni di Febbraio ad oggi praticamente non ci sono state serate serene: sempre molto nuvolose o coperte. Quindi mi sono dovuto accontentare delle 7 ore di integrazione.
la Nebulosa "IC405", nota anche con la sigla C31 e denominata "Flaming Star nebula" ( nebulosa Stella Fiammeggiante) ha una particolarità dovuta alla sua stella principale di +6^ magnitudine ( "AE Aurigae") che con le sue radiazioni la illumina. "AE Aurigae" non si è formata all'interno della nebulosa IC405 ma è una stella "fuggitiva" formatasi presso la nebulosa di Orione circa 2-3 milioni di anni fà e, a causa di interazioni gravitazionali, è stata sospinta via disperdendosi in direziione della nebulosa che sta attaversando ad alta velocità.

This beautiful and interesting nebula in the constellation of Auriga has proven to be quite faint and difficult to process. In fact, I was hoping to increase the integration to improve the signal, but from the first days of February to today there have been practically no clear evenings: always very cloudy or overcast. So I had to settle for 7 hours of integration. The Nebula "IC405", also known by the acronym C31 and called "Flaming Star nebula" (Flaming Star nebula) has a peculiarity due to its main star of +6th magnitude ( "AE Aurigae") which illuminates it with its radiation. "AE Aurigae" was not formed inside the IC405 nebula but is a "runaway" star formed near the Orion Nebula about 2-3 million years ago and, due to gravitational interactions, was pushed away dispersing in the direction of the nebula that it is crossing at high speed.

Here is a view of an ancient planetary nebula in the constellation Cassiopeia and known by several names including Sharpless 2-200 and HDW 2 (Hartl-Dengl-Weinberger 2). It was discovered in the early 1980’s by examining the 1960’s Palomar Observatory Sky Survey. You can read more about the discovery in an article titled “A newly discovered nearby planetary nebula of old age” by Authors: Weinberger, R., Dengel, J., Hartl, H., & Sabbadin, F.

Quando ho visto L’integrazione mi sono spaventato per L elevata quantità di nubi oscure che compongono questo complesso nebulare . NOn è conosciuto come le vocine Nord’America e Pellicano , ma merita L osservazione per le sue particolarità’ …IC5068 si trova nella costellazione del Cigno, regione di idrogeno ironizzato (HII), ricca di polveri oscure dalle forme diaboliche , luogo di nascita di giovani stelle formate dai caldi venti stellari.

A widefield shot of part of the famous supernova remnant in the southern constellation of Vela.
This image is an integration of data captured with a William Optics Redcat51 telescope and a ZWO 2600MC Pro camera. Approx 3 hours of data taken with no filter blended another 3 hours taken with an Optolong L-eXtreme filter. All post-processing was carriied out in PixInsight.
M16 Like you may have never see it before. I have to confess I know where the Eagle( its so small you would miss it) is but as a whole I see a sleeping face with closed Eyes and what looks like a beard. I even asked my wife to come look she did not even get past the door "there is a sleeping face, you can see the hair and the beard" and I did not say a word.
This is only possible With Carlos Taylor Smallrig getting to feel like its home. I do think we all get 100% dominated by longer focal lengths we do lose sight of the leaves on the tree . This is in part why I will not forget to use my nikon lens to bring to life the whole not just the macro with a 10".
Enjoy a whole new view and yes there has been some star reduction .
