NGC 6888 - Crescent Nebula
The Crescent Nebula (also known as NGC 6888, Caldwell 27, Sharpless 105) is an emission nebula in the constellation Cygnus, about 5000 light-years away from Earth. It was discovered by William Herschel in 1792. It is formed by the fast stellar wind from the Wolf-Rayet star WR 136 (HD 192163) colliding with and energizing the slower moving wind ejected by the star when it became a red giant around 250,000 to 400,000[citation needed] years ago. The result of the collision is a shell and two shock waves, one moving outward and one moving inward. The inward moving shock wave heats the stellar wind to X-ray-emitting temperatures. It is a rather faint object located about 2 degrees SW of Sadr. For most telescopes it requires a UHC or OIII filter to see. Under favorable circumstances a telescope as small as 8 cm (with filter) can see its nebulosity. Larger telescopes (20 cm or more) reveal the crescent or a Euro sign shape which makes some to call it the "Euro sign nebula".

WR 134
WR 134 is a variable Wolf-Rayet star located around 6,000 light years away from Earth in the constellation of Cygnus, surrounded by a faint bubble nebula blown by the intense radiation and fast wind from the star. It is five times the radius of the sun, but due to a temperature over 63,000 K it is 400,000 times as luminous as the Sun. WR 134 was one of three stars in Cygnus observed in 1867 to have unusual spectra consisting of intense emission lines rather than the more normal continuum and absorption lines. These were the first members of the class of stars that came to be called Wolf-Rayet stars (WR stars) after Charles Wolf and Georges Rayet who discovered their unusual appearance. It is a member of the nitrogen sequence of WR stars, while the other two (WR 135 and WR 137) are both members of the carbon sequence that also have OB companions. WR 134 has a spectrum with NIII and NIV emission between two and five times stronger than NV, leading to the assignment of a WN6 spectral type. The spectrum also shows strong HeII emission and weaker lines of HeI and CIV.

NGC 7129
NGC 7129 is a reflection nebula located 3,300 light years away in the constellation Cepheus. A young open cluster is responsible for illuminating the surrounding nebula. A recent survey indicates the cluster contains more than 130 stars less than 1 million years old. NGC 7129 is located just half a degree from nearby cluster NGC 7142. The nebula is rosebud-shaped; the young stars have blown a large, oddly shaped bubble in the molecular cloud that once surrounded them at their birth.

Sh2-223 & 224
SH2-223 is an emission nebula visible in the constellation Auriga. It is located about one degree east of η Aurigae; it has the appearance of a faint fuzzy arc oriented in the north-south direction, of which a greater densification is located at the centre of the arc itself. Cloud declination is moderately north, it can be easily observed mainly from the northern hemisphere regions, where it occurs circumpolar to mid-temperate latitudes. The object was considered to be a highly developed (and thus highly scattered) supernova remnant, located at a distance of 8000 well parsecs (26100 light-years), namely on the outer edge of the Milky Way, in the direction of the outer arm; it was given the acronym OA 184, as a supernova remnant, and its radio wave emissions were studied extensively. Sh2-224 is a very faint supernova remnant located approximately 14,700 lightyears distant in the constellation Auriga. This unusual celestial object is also designated VRO 42.05.01. The nebula created by the supernova explosion is composed of two visual parts. It is postulated the supernova explosion created a bubble like structure, visible in the top of the image. As the shockwave from the explosion progressed into a very low density region of the interstellar medium, a "wing" component was expelled, visible in the bottom of the image.

NGC 6543 - Cat's Eye Nebula
The Cat's Eye Nebula (also known as NGC 6543 and Caldwell 6) is a planetary nebula in the northern constellation of Draco, discovered by William Herschel on February 15, 1786. It was the first planetary nebula whose spectrum was investigated by the English amateur astronomer William Huggins, demonstrating that planetary nebulae were gaseous and not stellar in nature. Structurally, the object has had high-resolution images by the Hubble Space Telescope revealing knots, jets, bubbles and complex arcs, being illuminated by the central hot planetary nebula nucleus (PNN). It is a well-studied object that has been observed from radio to X-ray wavelengths.

NGC 2371
NGC 2371-2 is a dual lobed planetary nebula located in the constellation Gemini. Visually, it appears like it could be two separate objects; therefore, two entries were given to the planetary nebula by John Louis Emil Dreyer in the New General Catalogue, so it may be referred to as NGC 2371, NGC 2372, or variations on this name. It has also been called the double bubble nebula. The central star of the planetary nebula has a spectral type of [WO1], indicating a spectrum similar to that of an oxygen-rich Wolf–Rayet star.

NGC 1514
NGC 1514 is a planetary nebula in the constellation Taurus. Discovered on 13 November 1790 by William Herschel, it was described by him as a "singular phenomenon". Until then Herschel had been convinced that all nebulae were stars too distant to be resolved, but in this object he observed "a star with a faintly luminous atmosphere of circular shape". Photographs taken by Luboš Kohoutek in 1968 showed two nearly symmetrical bright condensations within the nebula in a northwest and southeast direction. The central star of this nebula differs from that found in other objects of this type: markedly bright (apparent magnitude +9.3) it shows an O-type spectrum as well as spectral characteristics of an A0 III-type star.2 It is currently thought to be an ellipsoidal shell with bright droplets within it along the polar axis. The nebula is believed to come from a common shell of a binary star. The orbital period of the system is estimated to be about 10 days with an initial mass of the parent star around 4.5 solar masses. Presumably the gas escapes from the largest star in the system.

Messier 76 - Little Dumbell Nebula
The Little Dumbbell Nebula, also known as Messier 76, NGC 650/651, the Barbell Nebula, or the Cork Nebula, is a planetary nebula in northern constellation Perseus. It was discovered by Pierre Méchain in 1780 and included in Charles Messier's catalog of comet-like objects as number 76. It was first recognized as a planetary nebula in 1918 by the astronomer Heber Doust Curtis. However, there is some contention to this claim, as Isaac Roberts in 1891 did suggest that M76 might be similar to the Ring Nebula (M57), being instead as seen from the side view.[2] The structure is now classed as a bipolar planetary nebula (BPNe), denoting two stars which have burst, leaving neutron star or white dwarf remnants and luminous envelopes. Distance to M76 is currently estimated as 780 parsecs or 2,500 light years,[4] making the average dimensions about 0.378 pc. (1.23 ly.) across.

NGC 1333
NGC 1333 is a reflection nebula located in the northern constellation Perseus, positioned next to the southern constellation border with Taurus and Aries. The nebula is visible as a hazy patch in a small telescope, while a larger aperture will show a pair of dark nebulae designated Barnard 1 and Barnard 2. It is associated with a dark cloud L1450 (Barnard 205). Estimates of the distance to this nebula range from 980–1,140 ly . This nebula is in the western part[of the Perseus molecular cloud and is a young region of very active star formation,[6] being one of the best-studied objects of its type. It contains a fairly typical hierarchy of star clusters that are still embedded in the molecular cloud in which they formed, which are split into two main sub-groups to the north and south. Most of the infrared emission is happening in the southern part of the nebula. A significant portion of the stars seen in the infrared are in the pre-main sequence stage of their evolution.

Sh2-103 - Veil Supernova Remnant Nebula
The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop, a supernova remnant. The source supernova was a star 20 times more massive than the Sun which exploded between 10,000 and 20,000 years ago. At the time of explosion, the supernova would have appeared brighter than Venus in the sky, and visible in daytime. The remnants have since expanded to cover an area of the sky roughly 3 degrees in diameter (about 6 times the diameter, and 36 times the area, of the full Moon). In order to capture it in its full splendor, a 9-panel mosaic was necessary, as well as more that one week to get the required data.

Messier 97
The Owl Nebula (also known as Messier 97, M97 or NGC 3587) is a starburst planetary nebula approximately 2,030 LY away in the constellation Ursa Major. The estimated age of the Owl Nebula is about 8,000 years. It is approximately circular in cross-section with faint internal structure. It was formed from the outflow of material from the stellar wind of the central star as it evolved along the asymptotic giant branch. The nebula is arranged in three concentric shells/envelopes, with the outermost shell being about 20–30% larger than the inner shell. A mildly owl-like appearance of the nebula is the result of an inner shell that is not circularly symmetric, but instead forms a barrel-like structure aligned at an angle of 45° to the line of sight.

Sh2-292 (Seagull Nebula)
IC 2177 is a region of nebulosity that lies along the border between the constellation Monoceros and Canis Major. It is a roughly circular H II region centered on the Be star HD 53367. This nebula was discovered by Welsh amateur astronomer Isaac Roberts and was described by him as "pretty bright, extremely large, irregularly round, very diffuse." The name Seagull Nebula is sometimes applied by amateur astronomers to this emission region, although it more properly includes the neighboring regions of star clusters, dust clouds and reflection nebulae. This latter region includes the open clusters NGC 2335 and NGC 2343. NGC 2327 is located in IC 2177. It is also known as the Seagull's Head, due to its larger presence in the Seagull nebula.

Sh2-275 (Rosette Nebula)
The Rosette Nebula (also known as Caldwell 49) is an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter. The cluster and nebula lie at a distance of 5,000 LY from Earth and measure roughly 130 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses.

Discovered in 1952 using a 25-inch SCT, it is difficult to observe due to its extremely low brightness.The nebulous area is fairly large with an almost spherical shell and filamentary structure. The remnant has an apparent diameter of approximately 3 degrees, an estimated distance of approximately 3000 (±350) LY, and an age of approximately 40,000 years. It is believed that after its stellar explosion a rapidly spinning neutron star known as pulsar PSR J0538+2817 was left behind in the nebula core, emitting a strong radio signal.

NGC 1499 (California Nebula)
This 2 panel mosaic shows the California Nebula, an emission nebula located in the constellation Perseus. It is so named because it appears to resemble the outline of the US State of California on long exposure photographs. It is almost 2.5° long on the sky and, because of its very low surface brightness, it is extremely difficult to observe visually. It can be observed with a Ha filter (isolates the Hα line at 656 nm) or Hβ filter (isolates the Hβ line at 486 nm) in a rich-field telescope under dark skies. It lies at a distance of about 1,000 LY from Earth. Its fluorescence is due to excitation of the Hβ line in the nebula by the nearby prodigiously energetic O7 star, Xi Persei (also known as Menkib).

NGC 1999
NGC 1999 is a dust-filled bright nebula with a vast hole of empty space represented by a black patch of sky, as can be seen in the photograph. It is a reflection nebula, and shines from the light of the variable star V380 Orionis. It was previously believed that the black patch was a dense cloud of dust and gas which blocked light that would normally pass through, called a dark nebula. Analysis of this patch by the infrared telescope Herschel (October 9, 2009), which has the capability of penetrating such dense cloud material, resulted in continued black space. This led to the belief that either the cloud material was immensely dense or that an unexplained phenomenon had been detected.

A telescopic view toward the constellation Cassiopeia, the colorful skyscape features the swept-back, comet-shaped clouds IC 59 (left) and IC 63. About 600 light-years distant, the clouds aren't actually ghosts, but they are slowly disappearing under the influence of energetic radiation from hot, luminous star gamma Cas. Gamma Cas is physically located only 3 to 4 light-years from the nebulae, just off the top right edge of the frame. Slightly closer to gamma Cas, IC 63 is dominated by red H-alpha light emitted as hydrogen atoms ionized by the star's ultraviolet radiation recombine with electrons. Farther from the star, IC 59 shows proportionally less H-alpha emission but more of the characteristic blue tint of dust reflected star light.

The NGC description refers to IC 5146 as a cluster of 9.5 mag stars involved in a bright and dark nebula. The cluster is also known as Collinder 470. It shines at magnitude +10.0/+9.3/+7.2. Its celestial coordinates are RA 21h 53.5m, dec +47° 16′. It is located near the naked-eye star Pi Cygni, the open cluster NGC 7209 in Lacerta, and the bright open cluster M39. The cluster is about 4,000 ly away, and the central star that lights it formed about 100,000 years ago; the nebula is about 12 arcmins across, which is equivalent to a span of 15 light years. When viewing IC 5146, dark nebula Barnard 168 (B168) is an inseparable part of the experience, forming a dark lane that surrounds the cluster and projects westward forming the appearance of a trail behind the Cocoon.

Sh2-129 & Ou4 (Flying Bat & Squid Nebulas)
Very faint but also very large on planet Earth's sky, a giant Squid Nebula cataloged as Ou4, and Sh2-129 also known as the Flying Bat Nebula, are both caught in this cosmic scene toward the royal constellation Cepheus. Discovered in 2011 by French astro-imager Nicolas Outters, the Squid Nebula's alluring bipolar shape is distinguished here by the telltale blue-green emission from doubly ionized oxygen atoms. Though apparently completely surrounded by the reddish hydrogen emission region Sh2-129, the true distance and nature of the Squid Nebula have been difficult to determine. Still, a recent investigation suggests Ou4 really does lie within Sh2-129 some 2,300 light-years away. Consistent with that scenario, Ou4 would represent a spectacular outflow driven by HR8119, a triple system of hot, massive stars seen near the center of the nebula. The truly giant Squid Nebula would physically be nearly 50 light-years across. This object has been in my bucket list for a while; I could finally shoot it in 2 panels. It's been processed as a (modified) bi-color image with Ha in the red channel and OIII in the green and blue channels. RGB image was only used to replace the stars.

Sh2-157 (Lobster Claw) + Sh2-161 (Bubble Nebula)
Sharpless 157, also known as the Lobster Claw Nebula, is a bright emission nebula in the constellation Cassiopeia. It lies just south of the better-known Bubble Nebula (Sh2-161 or NGC 7635). Within this image are a few other objects. Planetary Nebula PLN 110-0.1 is located near the center of the lower-left quadrant. The bright nebular spot near the center of the image is Lynd's Bright Nebula 537 (LBN537), also known as Sharpless 157a. The small cluster of stars just below the top pincer is Markarian 50 and the bright cluster of stars located below the bottom pincer is open cluster NGC 7510.

LBN 380 + Sh2-116
This H II region is part of the western Cygnus X complex. Three emission nebulas are listes in the DWB-Catalogue ("A list of optically visible HII regions" by Dickel, Wendker and Bieritz, 1969): DWB 191, DWB 192 and DWB 193. Several emission nebulas are listed in the Lynds' Catalogue of Bright Nebulae (LBN). This catalogue is not very accurate in this area, the coordinates does not point to the brightest nebula parts but in between. In the annotated image I have tried to correct this as it seems right to me. Sh2-116, also known as Abell 71 is a small, round shaped nebula. Abell 71 has a really weird history. First it was catalogued in 1955 by G.O. Abell as a planetary nebula and then someone decided it was an emission nebula but then people have realised it is actually an old, but true PN.

Messier 16 - Eagle Nebula
The Eagle Nebula (catalogued as Messier 16 or M16, and as NGC 6611, and also known as the Star Queen Nebula and The Spire) is a young open cluster of stars in the constellation Serpens, discovered by Jean-Philippe de Cheseaux in 1745–46. Both the "Eagle" and the "Star Queen" refer to visual impressions of the dark silhouette near the center of the nebula, an area made famous as the "Pillars of Creation" imaged by the Hubble Space Telescope. The nebula contains several active star-forming gas and dust regions, including the aforementioned Pillars of Creation. The Eagle Nebula is part of a diffuse emission nebula, or HII region, which is catalogued as IC 4703. This region of active current star formation is about 5700 light-years distant. A spire of gas that can be seen coming off the nebula in the northeastern part is approximately 9.5 light-years.

Cygnus Wall and The Gulf of Mexico
The portion of the nebula resembling Mexico and Central America is known as the Cygnus Wall. This region exhibits the most concentrated star formation. The North America Nebula and the nearby Pelican Nebula (IC 5070) are parts of the same interstellar cloud of ionized hydrogen (H II region). Between the Earth and the nebula complex lies a band of interstellar dust that absorbs the light of stars and nebulae behind it, and thereby determines the nebula's apparent shape. The distance of the nebula complex is not precisely known, nor is the star responsible for ionizing the hydrogen so that it emits light. If the star inducing the ionization is Deneb, as some sources say, the nebula complex would be about 1,800 light-years' distance, and its absolute size (6° apparent diameter on the sky) would be 100 light-years.

Sh2-132 - The Lion Nebula
This target encompasses the "first light" of the astronomical system Daniel Plathey and I just install in 'Entre Encinas y Estrellas' at Fregenal de la Sierra in Spain. This giant HII region, which I call the Dragon or Lion Nebula, is ionised by two WR stars (WR 152 and WR153) and OB stars in several embedded clusters. WR 153 and an O 8.5 star lie near the middle of the radio shell associated with this nebula. Available distance estimates locate Sh 2-132 in the Cep OB1 association within the Perseus arm. This nebula is also prominent in radio and infrared images. The first image is in narrowband light and the process followed the Hubble palette SII as red, Ha as green and OIII as blue. The second image is in visible light or just Red, green and blue, I added Ha to the red channel to enhance the nebulosity in this band.

Messier 97 - Owl Nebula
The Owl Nebula (also known as Messier 97, M97 or NGC 3587) is a planetary nebula located approximately 2,030 light years away in the constellation Ursa Major. The nebula is approximately 8,000 years old. It is approximately circular in cross-section with a little visible internal structure. It was formed from the outflow of material from the stellar wind of the central star as it evolved along the asymptotic giant branch. The nebula is arranged in three concentric shells, with the outermost shell being about 20–30% larger than the inner shell. The owl-like appearance of the nebula is the result of an inner shell that is not circularly symmetric, but instead forms a barrel-like structure aligned at an angle of 45° to the line of sigh. Messier 108 galaxy can by seen at the upper left of the image. Telescope: Meade Series 6000 APO 115 f/5.6 Camera: QHY-168C Filter: Optolong L-Pro Date: March 2020 Exposure: 29 x180" = 1.5 hrs |

IC 410 - Tadpoles Nebula
This close up shows off the otherwise faint emission nebula IC 410. It also features two remarkable inhabitants of the cosmic pond of gas and dust below and left of center, the tadpoles of IC 410. Partly obscured by foreground dust, the nebula itself surrounds NGC 1893, a young galactic cluster of stars. Formed in the interstellar cloud a mere 4 million years ago, the intensely hot, bright cluster stars energize the glowing gas. Composed of denser cooler gas and dust, the tadpoles are around 10 light-years long and are likely sites of ongoing star formation. Sculpted by winds and radiation from the cluster stars, their heads are outlined by bright ridges of ionized gas while their tails trail away from the cluster's central region. IC 410 lies some 10,000 light-years away, toward the nebula-rich constellation of Auriga.

IC 405 - Star Flaming Nebula
IC 405 (also known as the Flaming Star Nebula, SH 2-229, or Caldwell 31) is an emission and reflection nebula in the constellation Auriga, surrounding the bluish star AE Aurigae, it shines at magnitude +6.0. It surrounds the irregular variable this star and is located near the emission nebula IC410, the open clusters M38 and M36, and the K-class star Iota Aurigae. The nebula measures approximately 37.0' x 19.0', and lies about 1,500 light-years away from Earth. It is believed that the proper motion of the central star can be traced back to the Orion's Belt area. The nebula is about 5 light-years across.

NGC 1499 - California Nebula
The California Nebula is an emission nebula located in the constellation Perseus. It is so named because it appears to resemble the outline of the US State of California on long exposure photographs. It is almost 2.5° long on the sky and, because of its very low surface brightness, it is extremely difficult to observe visually. It can be observed with a Hβ filter (isolates the Hβ line at 486 nm) in a rich-field telescope under dark skies. It lies at a distance of about 1,000 light years from Earth. Its fluorescence is due to excitation of the Hβ line in the nebula by the nearby prodigiously energetic O7 star (also known as Menkib, seen at center below it in the inset at right).

IC 1805 - Heart Nebula
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 is an emission nebula showing glowing ionized hydrogen gas and darker dust lanes. The benefits of the Optolong L-enHance filter can be seen as Ha region are very prominent. The brightest part of the nebula (a knot at its western edge) is separately classified as NGC 896, because it was the first part of the nebula to be discovered. 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 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.

NGC 7000 + IC 5070 - North America &
Pelican Nebulas The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus, close to Deneb (the tail of the swan and its brightest star). The remarkable shape of the nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico. It is sometimes incorrectly[citation needed] called the "North American Nebula". The Pelican Nebula (also known as IC 5070 and IC 5067) is an H II region associated with the North America Nebula in the constellation Cygnus. The gaseous contortions of this emission nebula bear a resemblance to a pelican, giving rise to its name. The Pelican Nebula is located nearby first magnitude star Deneb, and is divided from its more prominent neighbour, the North America Nebula, by a molecular cloud filled with dark dust. So, taking advantage of these two beauties in the sky, I made a two panel mosaic !!!

NGC 7380 - Wizard Nebula
NGC 7380 (also known as the Wizard Nebula) is an open cluster discovered by Caroline Herschel in 1787. This reasonably large nebula is located in Cepheus. Located 7200 light years away, the Wizard nebula, surrounds developing open star cluster NGC 7380. Visually, the interplay of stars, gas, and dust has created a shape that appears to some like a fictional medieval sorcerer. The active star forming region spans about 100 light years, making it appear larger than the angular extent of the Moon. The Wizard Nebula can be located with a small telescope toward the constellation of the King of Aethiopia (Cepheus). Although the nebula may last only a few million years, some of the stars being formed may outlive our Sun.

NGC 6888 - Crescent Nebula
The Crescent Nebula (also known as NGC 6888, Caldwell 27, Sharpless 105) is an emission nebula in the constellation Cygnus, about 5000 light-years away from Earth. It was discovered by William Herschel in 1792. It is formed by the fast stellar wind from the Wolf-Rayet star WR 136 (HD 192163) colliding with and energizing the slower moving wind ejected by the star when it became a red giant around 250,000 to 400,000 years ago. The result of the collision is a shell and two shock waves, one moving outward and one moving inward. The inward moving shock wave heats the stellar wind to X-ray-emitting temperatures.

IFN - Interflux Nebula
My friends from CAV (Chiefland Astronomical Village) in Florida, USA invited me to spend the April's New Moon sharing time at their facilities. Bill Williams and his family, not only invite Cynthia and I to stay in their astroranch and also to use theirs observatory. For some years I was wondering if I could image the IFN, which is a very, very faint nebulosity. From the Mandel-Wilson Catalogue, Steve Mandel described it thus: "Integrated Flux Nebulae is the term I've coined to describe high galactic latitude nebulae that are illuminated not by a single star (as most nebula in the plane of the Galaxy are) but by the energy from the integrated flux of all the stars in the Milky Way. These nebulae clouds, an important component of the Interstellar Medium, are composed of dust particles, hydrogen and carbon monoxide and other elements." I'm extremely happy with the result, we're able to show the faint IFN around Messier 81 and 82 with only five hours exposure time !!! Thanks Bill !!!!

NGC 6992 - Western Veil Nebula
The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop, a supernova remnant, many portions of which have acquired their own individual names and catalogue identifiers. The source supernova was a star 20 times more massive than the Sun, which exploded around 8,000 years ago. The analysis of the emissions from the nebula indicate the presence of oxygen, sulfur, and hydrogen. The Cygnus Loop is also a strong emitter of radio waves and x-rays. I took the license of coloring the Ha data in both yellow and red. Which one you like best?

So on 21/03/18 while still in Perth, I pointed my gear to it. Richard Tonello this is for you Mate !!! CG 4, commonly referred to as God's Hand, is a star-forming region located in the Puppis constellation, about 1,300 light-years from Earth. It is one of several objects referred to as "cometary globules", because its shape is similar to that of a comet. It has a dense head formed of gas and dust, which is around 1.5 ly in diameter, and an elongated faint tail around 8 ly in length. CG 4, and the nearby cometary globules, generally point away from the Vela Supernova Remnant, located at the center of the Gum Nebula. The galaxy at 12 o'clock is PGC 21338 shinning at 14.55 mag.

NGC 3372 - Eta Carinae
THIS IMAGE HAS BEEN PUBLISHED IN "AMATEUR ASTRONOMY" MAGAZINE SUMMER 2015 !!!!!!!!!!!!!!!!
The Carina Nebula is a large bright nebula that has within its boundaries several related open clusters of stars. The red star in the center of the image is currently the most luminous star in our Milky Way galaxy, possibly as much as 120 to 150 times the mass of the Sun, and emitting the light of 4,000,000 Suns. The nebula lies between 6,500 and 10,000 light-years from Earth in the constellation of Carina. This nebula is one of the largest diffuse nebulae in our skies. Although is some four times as large and even brighter than the famous Orion Nebula, the Carina Nebula is much less well known, due to its location in the southern sky.
This broad panorama of the Carina Nebula was composed as a 6 frames mosaic - my first mosaic project - for a combined exposure of 18 hours. I think, I had expent almost the same time processing it...
Many features, scattered across a spectacular celestial landscape of gas, dust and young stars have emerged.
Eta Carina is nearing the end of its life, and is surrounded by a huge nebula, cast off by numerous eruptions of stars over the last several centuries; it is expected to explode into supernova at any time. Would be this one of the last images of Eta Carina before the explosion?

The Tarantula Nebula or 30 Doradus is an HII region in the Large Magellanic Cloud that lies 160,000 light-year away from Earth. It is an extremely luminous non-stelar object, its luminosity is so great that if it were as close to our planet as the Orion Nebula , Tarantula would cast shadows. It's also the most starbust region known in the Local Group of galaxies. The closest supernova observed since the invention of the telescope, Supernova 1987A ocurred in the outskirts of Tarantula Nebula. Telescope: Meade LX850 12" f/8 Camera: SBIG STF-8300C Date: March 2015 Exposure: 57 x 3' = 2.8 hrs |

NGC 2359 - Thor's Helmet
NGC 2359 is an emision nebula that lies 12,000 far from Earth in the constellation Canis Major. The central star is a Rayet-Wolf type, an extremely hot giant thought to be in the pre-supernova stages of evolution, interaction with a neaby large molecular cloud are thought to have contributed to its complex shape and curved bow-shock structure. Telescope: Meade LX850 12" f/8 Camera: SBIG STF-8300C Date: February 2015 Exposure: 72 x 3' = 3.6 hrs |

NGC 3132 - Eight-Burst Nebula
This planetary nebula lies around 2,000 light-year away in the constellation Vela. In shape, size, form and brightness, NGC 3132 compares well with M57, and for that reason it is commonly called Southern Ring. Telescope: Meade LX850 12" f/8 Camera: SBIG STF-8300C Date: February 2015 Exposure: 60 x 3' = 3 hrs |

Messier 20 - Trifid Nebula
The Trifid Nebula or NGC 6514 is an HII region located in the constellation Sagittarius at 5,000 ligth-years away from Earth. This object is an unusual combination of open cluster of stars, an emisison nebula, a reflection nebula and a dark nebula. This image was taken through a remote telescope (T3) from iTelescope. Telescope: Takahashi TOA 150 f/7.3 Camera: SBIG STF-8300C Date: November 2014 Exposure: 6 x 10' = 1 hrs |
