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.

LBN 691
Lynds Bright Nebula 691 (MBM 32) is a molecular cloud in Ursa Major, a dense core of high galactic cirrus cloud. A molecular cloud, is a type of interstellar cloud, the density and size of which permit the formation of molecules, most commonly molecular hydrogen (H2). The molecular cloud MBM 32 was first catalogued as LBN 691 by Lynds (1965) and later as MBM32 by MBM (1985). It is located in the complex known as the Ursa Major cirrus cloud. This cloud is one of the first cirrus clouds where H2CO and NH3 organic compounds were detected.

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.

Sh2-240 - Simeis 147 (Spaghetti Nebula)
This image is a crazy 9 panel mosaic featuring Simeis 147, also known as the Spaghetti Nebula, SNR G180.0-01.7 or Sharpless 2-240, is a supernova remnant (SNR) in the Milky Way, straddling the border between the constellations Auriga and Taurus. 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.

Sh2-190 (Heart Nebula)
This image is a 4 panel mosaic featuring the Heart Nebula, IC 1805, Sharpless 2-190 that lies some 7500 LY away from Earth and is located in the Perseus Arm of the Galaxy in the constellation Cassiopea. It is an emission nebula showing glowing ionized hydrogen gas and darker dust lanes. 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 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.

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).

Messier 1 (Crab Nebula)
The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant and pulsar wind nebula in the constellation of Taurus. The common name comes from William Parsons, who observed the object in 1840 using a 36-inch telescope and produced a drawing that looked somewhat like a crab. The nebula was discovered by English astronomer John Bevis in 1731, and it corresponds with a bright supernova recorded by Chinese astronomers in 1054. The nebula was the first astronomical object identified that corresponds with a historical supernova explosion.

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.

IC 1396 (Elephant's Trunk Nebula)
The Elephant's Trunk Nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light-years away from Earth. The piece of the nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright, massive star (HD 206267) that is just to the east of IC 1396A. (In the Spitzer Space Telescope view shown, the massive star is just to the left of the edge of the image.) The entire IC 1396 region is ionized by the massive star, except for dense globules that can protect themselves from the star's harsh ultraviolet rays. This is a 4 panel mosaique.

IC 59 & IC 63 (Ghost of Cassiopeia Nebula)
These bright rims and flowing shapes look ghostly on a cosmic scale. 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 field of view spans about 1 degree or 10 light-years at the estimated distance of gamma Cas and friends.

IC 5146 + Barnard 168 (Cocoon Nebula)
IC 5146 (also Caldwell 19, Sh 2-125, and the Cocoon Nebula) is a refletion/emission nebula and Caldwell object in the constellation Cygnus. 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.

About 1,000 light-years away and drifting above the plane of our Milky Way galaxy, the dusty molecular cloud is part of a complex of dark nebulae mapped toward the Cepheus flare region. Across the spectrum, astronomical explorations of the obscuring interstellar clouds reveal energetic shocks and outflows associated with newborn stars, including the telltale reddish glow from scattered Herbig-Haro objects seen in this sharp image. Distant background galaxies also lurk on the scene, visually buried behind the dusty expanse. The deep telescopic field of view imaged with broadband filters spans about two full moons on the sky, or 17 light-years at the estimated distance of LDN 1251.

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). Telescope: Meade Series 6000 APO 115 f/5.6 Camera: QHY-168C Filter: Optolong L-enHance Date: February 2020 Exposure: 2 x 30 x 240" = 4.0 hrs |

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.

The object is more commonly called by the cluster designation IC 1848. Small emission nebula IC 1871 is present just left of the top of the head, and small emission nebulae 670 and 669 are just below the lower back area. This complex is the eastern neighbor of IC 1805 (Heart Nebula) and the two are often mentioned together as the "Heart and Soul".

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?

Cometary Globule 4 - God's Hand
Last year the great astronomer and friend Richard Tonello gave me a challenge: "Go out there and get an image of the Cometary Globule 4 (CG4) referred to as God's Hand !!!" 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?

This bright diffuse reflection nebula is part of the Orion Molecular Cloud Complex and is about 1,600 light-years from Earth. I had been always fascinanted by this object, I had patiently waiting until 2016 summer to image it myself. Telescope: Meade LX850 12" f/5.7 (telecompressor Lepus 0.62X) Camera: SBIG STF-8300C Date: March 2016 Exposure: 35 x 10' = 5.8 hrs |

NGC 3199
This nebula lies at about 12,000 light-years away, a glowing cosmic cloud in the southern constellation of Carina. NGC 3199 is about 75 light-years across, near the center of the ring is a Wolf-Rayet star, a massive, hot, short-lived star that generates an intense stellar wind. In fact, Wolf-Rayet stars are know to create nebulae. Telescope: Meade LX850 12" f/8 Camera: SBIG STF-8300C Date: April 2015 Exposure: 36 x 10' = 6 hrs |

NGC 2818 & Melotte 96
NGC 2818 is a beautiful planetary nebula, the gaseous shroud of a dying sun-like-star. It could well offer a glimpse of the future that awaits our own Sun after spending another 5 billion years or so steadily using up hydrogen at its core, and then finally helium, as fuel for nuclear fusion. The nebula seems to lies within an open cluster, Melotte 96 that is some 10,000 ligth-years distant toward the southern constellation Pyxis. But, truth is that only by chance NGC 2818 is found in the line of sight to the star cluster. Telescope: Meade LX850 12" f/8 Camera: SBIG STF-8300C Date: April 2015 Exposure: 9 x 10' = 1.2 hrs |

NGC 2736 - Herschel's Ray
The Pencil nebula is part of the Vela Supernova Remanent, located near the Vela pulsar in the constellation of same name. This faint object resided 815 light-years away from our solar system and it was discovered by John Herschel in 1835. This target was proposed to me by my friend Bruce Pipes that lives in USA and could not image it due to NGC 2736 south latitud. At the time he gave my this challenge, this type of objects was not even in my deepest dreams, but ... here it is !!!

NGC 2070 - Tarantula Nebula
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.

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 |
