NGC 2264 NGC 2264 is a diffuse emission nebula and cluster in the constellation Monoceros. It's unusual in that the NGC designation also includes the Cone Nebula, the Snowflake Nebula and the Christmas Tree Nebula. All of these objects lie around 2300 light-years from Earth. In the center of the nebula are a number of hot, new stars that are hot enough to excite the nearby gases enough that they begin to glow in visible light Sh2-129, OU4 - The Flying Bat and Squid Nebulae In the constellation Cepheus is the large nebula - The Flying Bat, and right in the middle is the very faint Squid Nebula. This one was really difficult to process. Just couldn't figure out how to bring out the colors the way I would like. This one would be worth re-doing sometime when I have a little more PixInsight under my belt. They both lie about 2300 light-years away and the Squid nebula is about 50 light-years across NGC 1499 - The California Nebula The California Nebula is an emission nebula in the constellation Perseus. Although in this image it looks fairly bright, it actually has a very low surface brightness which makes it difficult to observe visually. It lies about 1000 light-years from the Earth Henize 70 Henize 70 was first observed in 1950. Originally it was thought to be a Supernova remnant. Then in 1956 it was added to catalogs as a planetary and emission nebula. Over the years most astronomers stuck with the supernova theory. As it turns out, Henize 70 is a superbubble - a mass of gas that seems to be eroding from nearby stellar winds. This image is a second version - experimenting with some new processing techniques. The first version is on the second Nebula page and was processed in SHO. This version was processed in HOO

IC 4812 - The Coalsack Nebula The Coalsack Nebula lies about 600 light-years from Earth in the Southern constellation of Crux (the Southern Cross). It is one of the rare DSOs that can be seen with the naked eye. It plays an important part in the mythologies of the Australian Aboriginal People, and forms the head of the Emu in the Sky. For the Inca people, this nebula was called Yutu, a partridge-like bird in South America Telescope Live Picture of the Day In September of 2023 I was lucky enough to have one of my images selected as the Telescope Live Picture of the Day. It's really nice to be recognized. The picture is the one directly to the left Messier 16 - The Eagle Nebula (Pillars of Creation) In the constellation Serpens lies Messier 16, a diffuse emission nebula. It is about 5700 light-years from Earth and contains numerous active star-forming regions and clusters, the main cluster containing around 8100 stars. The Eagle Nebula was made famous in 1995 when a Hubble image was released that came to be named "The Pillars of Creation." The Pillars are an excellent example of the erosion of the molecular cloud that formed the hot, new stars. The intense radiation from the new stars is what causes the erosion Messier 42 - The Great Orion Nebula Measuring about 24 light-years across and 1344 light-years from Earth, the Great Orion Nebula is a prime example of an emission nebula. It is a naked-eye object and can be identified as the middle "star" in Orion's sword. It is the most photographed and studied nebula and has added considerably to our knowledge of star and planetary systems formation. This is one of several M42s that I've done with various different telescopes and cameras. It's fun to re-do an image as I learn new techniques in processing

Messier 42 - The Great Orion Nebula This is another version of the Orion Nebula using the same data set as the image to the left. This time I used some of the processes in Affinity Photo 2. I actually came across this look by accident. It was a version that popped up when I was using Tone Mapping Persona. This would be an awesome image if I could figure out how to lighten the left side without lightening the rest of the image. There's still a lot of nebulosity hidden in there NGC 3293 In the constellation Carina lies NGC 3293, an open cluster, which boasts over 100 stars. It was discovered by Nicholas-Louis de Lacaille in 1751. Two of the brand new stars are blue super-giants. It is about 12 million years old. The most massive of the stars have congregated toward the center of the cluster Messier 17 - The Omega Nebula or Swan Nebula Lying about 5500 light-years from Earth, the nebula spans around 15 light-years in diameter. The larger cloud of gas and dust from which the nebula formed is about 40 light-years in diameter. It is one of the most massive and brightest star-forming regions in our own Milky Way. It was discovered by Phillipe Loys de Cheseaux in 1745 and finally cataloged by Charles Messier in 1765 Sharpless-86 (Sh2-86) This nebula is an emission and dark nebula located in the constellation Vulpecula. There are numerous pillars of dust and gas that are eroding because of the stellar radiation (solar wind) from the star cluster that is center-left (NGC 6823). There are also numerous Bok globules throughout the nebula. The globules are areas around protostars where planets will form around that particular star

Small Magellanic Cloud (SMC) NGC 292 The Small Magellanic cloud is a companion galaxy to our own Milky Way and sits about 200,000 light-years from us. It is an irregular dwarf galaxy and has a mass of about 7 billion solar masses with several hundred million stars. It is one of the most distant objects that can be seen with the naked eye. It is visible throughout the entire southern hemisphere and up to about 15 degrees north of the Equator Large Magellanic Cloud (LMC) LRGB The LMC is a satellite galaxy to the Milky Way. It lies about 163,000 light-years away. The LMC is classified as a Magellanic spiral, in that it contains a stellar bar that is geometrically off center, suggesting that it was a barred dwarf spiral galaxy before its spiral arms were disrupted, likely by tidal interactions from the Small Magellanic Cloud (SMC) and the Milky Way's gravity Large Magellanic Cloud (LMC) HLRGB This image is almost exactly the same as the one just to the left. The difference is that this one has Hydrogen Alpha (Ha) added. Hydrogen, in this case is in the red channel which accentuates the hydrogen regions in the image. The bright white area in the lower-right is the Tarantula Nebula NGC 2070 - The Tarantula Nebula The Tarantula Nebula is a large HII region in the Large Magellanic Cloud. In the previous two images above, it is the bright area in the lower-right of the LMC. It lies about 160,000 light-years from Earth. It is also one of the most luminous non-stellar objects in the sky. If it were as close to us as the Orion Nebula it would cast visible shadows. It is also the most active starburst region in our local group of galaxies

NGC 2064 NGC 2064 is a reflection nebula in the constellation Orion. The colors of the nebula are due to the reflected light of young, very hot, bright stars in the central blue area. It was first cataloged by John Louis Emil Dreyer in 1888. I like this image as it has some pretty cool texture NGC 6729 Located 424 light-years from us in the constellation Corona Australis lies this emission/reflection nebula. Some areas glow due to stellar radiation from stellar nurseries while other areas simply reflect the light from new, very hot stars. It was discovered by Johann Friedrich Julius Schmidt in 1861 Messier 97 - The Owl Nebula In the northern constellation of Ursa Major lies the Owl Nebula. It's a planetary nebula that was formed about 8,000 years ago when the primary star shed its outer atmosphere leaving behind a white dwarf. It was discovered by Pierre Mechain (who was an observing colleague of Charles Messier) in 1781. It was added to Messier's catalog one month after its discovery. Normally I wouldn't have the sky background so unnaturally dark, but I couldn't figure out how to get rid of some artifacts, so I just darkened it up to get rid of them Messier 20 - The Trifid Nebula Discovered by Charles Messier in 1764, it is a combination of open cluster stars, emission nebula and reflection nebula. This image was done in the SHO Hubble Palette, or false color. The central area has an open cluster that sports about 3100 young, hot stars, the largest of which has the mass of about 20 solar masses

IC 4604 Right in the center of the blue section of this nebula lie three stars that are called Rho Ophiuchi in the constellation Ophiuchus. The surrounding gas reflects the light from these hot, young stars making this a reflection nebula. There are also some areas of dark nebulosity on the left side. The whole complex is called IC 4604. IC 4604 is one of the closest star-making regions to Earth and is about 540 light-years away Barnard 33 and NGC 2024 - The Horsehead and Flame Nebulae The Horsehead Nebula was discovered by Williamina Fleming in 1888 on a photographic plate. It is illuminated from behind by hot, young stars. Some of their light also peeks through just to the left. The Flame Nebula on the far left side is an emission nebula, meaning that the hot, just formed stars in the middle are heating the surrounding gas until it glows. Both of these objects are some of the most imaged objects by astrophotographers and are about 1350 light-years away. I think, out of all the images that I've processed, this is my favorite. It was processed in SHO false color Barnard 33 - The Horsehead Nebula This is another view of the Horsehead Nebula using a different telescope from the image to the left. The one to the left was taken with a wide field telescope, while this one used a telescope with a lot more magnification. What a nice closeup! In this image you can see nebulosity streaking upward. The stars behind the cloud of gas are emitting massive amounts of energy in the form of solar winds which, as well as eroding the cloud, can actually push the gas away from the direction of the star NGC 6188 - The Fighting Dragons of Ara and NGC 6164 The Dragon's Egg The Dragons of Ara is an emission nebula located in the constellation Ara. There are a number of massive, young stars buried in the center that are heating the surrounding gas enough that it glows. Some of the new stars are only a few million years old. It is located about 4000 light-years away. The Dragon's Egg, toward the bottom, is a planetary nebula that was created by a star about 40 times the mass of our Sun as it underwent some late-life convulsions. The outer halo is probably from an earlier active period of the star.

IC 4685 This nebula has both reflection and emission components. It lies around 4000 light-years away and is found in the constellation Sagittarius. It doesn't get imaged often as both M8 and M20 are right nearby. It is composed of mostly HII gas that is usually depicted in red. Using variations of the Hubble Palette (in this case, SHO) it's fun to make something different Messier 1 - The Crab Nebula Originally observed by John Bevis in 1731, it was again observed independently by Charles Messier in 1758 and added to his list. It is a supernova remnant in the constellation Taurus. It is also the first astronomical object that corresponds to a historical event. The supernova was observed as a "Guest Star" in 1054 by the Chinese. At the center of the nebula is the original star (the Crab Pulsar) that is now a neutron star that measures about 18 miles across and spins at a rate of 30.2 times per second. This supernova remnant lies about 6500 light-years from us. The sky background is unusually black in this image. I had a lot of trouble getting rid of some processing artifacts so I ended up just making the background a bit blacker. It didn't solve the problem, only hid it Sh2-86, NGC 6820 and NGC 6823 There is a lot going on here in this picture. The overall area is a faint emission nebula called Sh2-86 in Vulpecula. Within this nebula lies another reflection nebula called NGC 6820. That is the brighter blue area in the center. In front of the blue reflection area is an area of dark nebula. The large dark column points to an open star cluster known as NGC 6823. The fun part about processing an image in false color (in this case SHO), is that you can discover a lot more detail than if you were working with regular RGB. In this and many of the previous images you can see that these objects are often part of a much larger complex of dust and gas NGC 1491 In the northern constellation of Perseus we have a relatively bright, but small emission nebula, NGC 1491. This image was processed in false color (SHO). Normally emission nebulae are very heavy in HII which is usually presented as red. Processing an image in different color schemes allows us to see different details at different frequencies

NGC 3199 This is an emission nebula in the constellation Carina. It was discovered by the Scottish astronomer James Dunlop in 1826. Originally this nebula was thought to have formed as the result of "Bow Shock" from the nearby Wolf-Rayet star WR-18. As it turns out, this is just a cloud of gas and dust formed in normal space. It is also known as the Banana Nebula LDN 858 A dark nebula in the constellation Cygnus (The Swan). There really isn't a lot of information on this object other than it being a dark nebula. Even though it is classified as dark, with the wonders of software I was able to brighten it up a bit. This image was done in the HOO palette Sh2-190 and Sh2-199 - The Heart and Soul Nebulae Sh2-190 – The Heart Nebula is an emission nebula located in the constellation Cassiopeia. It lies about 7500 light-years from Earth. It is composed primarily of Hydrogen gas as well as smaller amounts of ionized Oxygen and Sulfur gasses. Its shape is due to solar winds from a small open cluster near the center. This open cluster can claim a number of stars that are more than 50x the mass of the Sun. The Heart Nebula is the one in the lower right. Sh2-199 = The Soul Nebula is also in Cassiopeia and is 7500 light-years away. It contains numerous small open clusters and other small emission nebulae. There are a couple of small galaxies nearby. These two nebulae are usually referred to together as the Heart and Soul Nebulae RCW 16, Sh2-311 (NGC 2467) - Skull and Crossbones Nebula This nebula is located in the constellation Puppis. Puppis being the poop deck of the ship Argo, sailed by Jason and the Argonauts of Greek mythology. Some say that if you look at the image just right it looks like the face of a mandrill. This nebula is a region of gases that form a large star-making factory. Recent studies have detected at least 45 proto-stars (in the process of being formed). The region is dominated by the massive young star on the left side

Messier 78 Messier 78 is a reflection nebula in the constellation Orion. It lies about 1350 light-years away from us. It is the brightest nebula in its local area that includes other nebulae such as NGC 2064, 2076 and 2071. There are two new stars behind the gas in the center that provide the light that reflects off the gas. The two stars can be seen only with infrared imaging Sh2-297 This object is an emission nebula that sits in the constellation of Canis Major. It is actually the bright area in the center, and is part of the larger nebula Sh2-296 (The Seagull Nebula). It is about 4000 light-years away from us Messier 16 - The Eagle Nebula (Pillars of Creation) In the constellation Serpens lies Messier 16, a diffuse emission nebula. It is about 5700 light-years from Earth and contains numerous active star making regions and clusters, the main cluster containing around 8100 stars. The Eagle Nebula was made famous in 1995 when a Hubble image was released that came to be named "The Pillars of Creation." The Pillars are an excellent example of the erosion of the molecular cloud that formed the hot, new stars. The intense radiation from the new stars is what causes the erosion. This is a slightly different version than the one above NGC 2174 - The Monkey Head Nebula The Monkey Head is located in the constellation Orion and is about 6400 light-years away. The monkey's head is the large, round structure in the upper-right. There is an open cluster of very hot, young new stars just to the upper-right of center. These stars emit huge amounts of radiation in the form of stellar winds that erode and blow away gas which leaves behind unusually shaped structures like those in the lower half of the image. The color palette is SHO

RCW 19 This emission nebula is just a small part of a greater molecular cloud in Puppis that weighs in at about 200,000 solar masses. The color palette is OHS IC 405 - The Flaming Star or Auriga Nebula There's a lot of action packed into this object. First of all, it is both an emission and reflection nebula that lies about 1500 light-years away from us. The bright reddish area to the left is IC 405, The Flaming Star Nebula. At the top center is IC 410. This reflection nebula also contains an embedded open cluster - NGC 1893. Just outside of the image there are a couple more clusters Sh2-129 - The Flying Bat Nebula In the constellation Cepheus is the large nebula - The Flying Bat, and right in the middle is the very faint Squid Nebula. This one was really difficult to process. I just couldn't figure out how to bring out the colors of the Squid the way I would have liked. This one would be worth re-doing sometime when I have a little more PixInsight under my belt. They both lie about 2300 light-years away, and the Squid Nebula is about 50 light-years across NGC 2264 This nebula is in the constellation Monoceros. It lies about 2700 light-years away from us. NGC 2264 actually refers to two objects: The Cone Nebula and the Christmas Tree Nebula. Also within this huge reflection nebula are the Fox Fur and Snowflake Nebulae
