The Andromeda Galaxy is one of the most distant objects that can be seen with the naked eye. The galaxy is commonly located in the sky in reference to the constellations Cassiopeia and Pegasus.
The Andromeda Galaxy, also known as Messier 31, M31, or NGC 224 and originally the Andromeda Nebula, is a barred spiral galaxy approximately 2.5 million light-years (770 kiloparsecs) from Earth and the nearest major galaxy to the Milky Way. The galaxy’s name stems from the area of Earth’s sky in which it appears, the constellation of Andromeda, which itself is named after the Ethiopian (or Phoenician) princess who was the wife of Perseus in Greek mythology.
Andromeda is best seen during autumn nights in the Northern Hemisphere when it passes high overhead, reaching its highest point around midnight in October, and two hours later each successive month. The 27 subs for this image were captured in Nov 2020 and Jan 2021.
In early evening, it rises in the east in September and sets in the west in February. From the Southern Hemisphere the Andromeda Galaxy is visible between October and December, best viewed from as far north as possible. Binoculars can reveal some larger structures of the galaxy and its two brightest satellite galaxies, M32 and M110.
An amateur telescope can reveal Andromeda’s disk, some of its brightest globular clusters, dark dust lanes and the large star cloud NGC 206.

The Lagoon is a large gas cloud and very bright emission Nebula found in our southern skies within the constellation Sagittarius. This image is comprised of 27 3-minute exposures (81 mins). As it sits very low in my southern sky, the trees interfere just after crossing the meridian limiting the amount data captured.
M20, the Trifid Nebula, is seen in the top of this image. IC1275 is the paw looking gas cloud just to the left of the Lagoon Nebula.
The Lagoon Nebula is estimated to be between 4,000-6,000 light-years away from the Earth. In the sky of Earth, it spans 90′ by 40′, which translates to an actual dimension of 110 by 50 light years. In other words, IT’S HUGE!
Like many nebulas, it appears pink in time-exposure color photos but is gray to the eye peering through binoculars or a telescope, human vision having poor color sensitivity at low light levels.
The nebula contains a number of Bok globules (dark, collapsing clouds of protostellar material), the most prominent of which have been catalogued by E. E. Barnard as B88, B89 and B296.
It also includes a funnel-like or tornado-like structure caused by a hot O-type star that emanates ultraviolet light, heating and ionizing gases on the surface of the nebula.
The Lagoon Nebula also contains at its centre a structure known as the Hourglass Nebula (so named by John Herschel), which should not be confused with the better known Engraved Hourglass Nebula in the constellation of Musca. In 2006 the first four Herbig–Haro objects were detected within the Hourglass, also including HH 870. This provides the first direct evidence of active star formation by accretion within it.
Bottom line: The Lagoon Nebula, aka M8, is the largest and brightest of a number of nebulosity’s in and around the famous Teapot asterism in the constellation Sagittarius.
After more than 30 years of presenting music programs in Charlotte, the Tosco Music non-profit launched a full weekend of FabFest in 2019 with the mission of “enabling music lovers of all ages and cultures to come together around the universal popularity of the music of the Beatles”. Of course the pandemic wasn’t in the cards but 2 years later they’re back and the Beatles Tribute show was awesome!

Eagle Nebula – “Pillars of Creation” – (also known as the Star Queen Nebula and The Spire) is a young open cluster of stars in the constellation Serpens.
Both the “Eagle” and the “Star Queen” refer to visual impressions of the dark silhouette near the center of the nebula.
The nebula contains several active star-forming gas and dust regions, including the aforementioned Pillars of Creation. The Eagle Nebula lies in the Sagittarius Arm of our Milky Way.

Roughly 2,400 light-years away and lying in the plane of our Milky Way galaxy, the Cave Nebula is a diffuse emission nebula, within a larger nebula complex that includes a reflection nebula, and dark nebula. It is formed of gases that emit their own light. The bright arc that forms the mouth of the cave is an active birthplace for stars, known as an H II region, where hot clouds of atomic hydrogen have become ionized.
Having a magnitude of about 8 and a span of roughly 40 light-years, Caldwell 9 is a diffuse and low-contrast object, so it can still be difficult to find in the sky. Caldwell 9 is tantalizing to researchers because, according to radio and near-infrared studies of this nebula, the area is bursting with young, hot stars popping into existence.
Christmas Tree cluster, Cone Nebula, Fox Fur Nebula
This may be the most festive target in our night sky. A beautiful target contrasted by many layers of dust clouds and dark nebula. NGC 2264 is the designation number that identifies two astronomical objects as a single object: the Cone Nebula, and the Christmas Tree Cluster. Two other objects are within this designation but not officially included, the Snowflake Cluster, and the Fox Fur Nebula. The top of the structure is the Cone Nebula overlaid with the Christmas Tree star formation. Just under the Cone Nebula is the Fox Fur Nebula, named after its resemblance to the fox furs common in our history.
This image consists of 32 240s & 123 360s exposures (a little over 14 hours) with the ASI071MC Pro & WO Z73 scope with flattener riding the SW EQ6r Pro mount. Processed manually in PixInsight.
All of the objects are located in the Monoceros constellation and are located about 800 parsecs or 2,600 light-years from Earth. NGC 2264 is the location where the Cone Nebula, the Stellar Snowflake Cluster and the Christmas Tree Cluster have formed in this emission nebula. For reference, the Stellar Snowflake Cluster is located 2,700 light years away in the constellation Monoceros. The Monoceros constellation is not typically visible by the naked eye due to its lack of colossal stars. The Snowflake Cluster was granted its name due to its unmistakable pinwheel-like shape and its assortment of bright colors. The Christmas Tree star formation consists of young stars obscured by heavy layers of dust clouds. These dust clouds, along with hydrogen and helium are producing luminous new stars.
The Cone Nebula is very similar to the famous Pillars of Creation. At 430mm of focal length with this telescope, the entire tree and more was able to fit in our frame. You can see the Cone Nebula on the top right and the Fox Fur nebula around the upper middle-left (just below the bright middle star). The Christmas Tree cluster can easily be seen, going from the Cone Nebula to the bright star in the center. That bright star represents the tree base.
I hope you enjoy this image as much as I do. She’s a beauty!
Messier 81 (M81), also known as Bode’s Galaxy, is a grand design spiral galaxy located in the constellation Ursa Major. The galaxy lies at an approximate distance of 11.8 million light years from Earth and has an apparent magnitude of 6.94. It also has the designation NGC 3031. Bode’s Galaxy is home to over 250 billion stars and is the most remote blueshifted (moving toward us) large galaxy known.
This image is a stack of 5 hours of exposures taken from my driveway. Primary imaging gear – Telescope is the WO Z73 w/flat73A (430mm doublet refractor f5.9). Camera is the ZWO ASI071MC Pro cooled to 20f. Computerized Equitorial mount is the SkyWatcher EQ6r Pro. The support ensemble include the QHY Polemaster, WO 50mm guidescope with ZWO ASI120mm mini guide camera, Pegasus PBA, Intel NUC, Senso Sesto 2 Electronic Focuser w/temp probe. The software suite include windows 10 pro platform, Astro Photography Tool (APT) for image acquisition and auto focusing, PHD2 for guiding, ASTAP for plate solving, eqmod and ascom provide the interface support. Image processing was done manually in PixInsight. Metadata information added in Adobe Bridge and JPEG conversion performed in PhotoShop.
I wasn’t certain my wide focal length scope at 430mm would adequately capture these very small targets. I look forward to a longer FL refractor telescope in my future for these size targets, but for now this is it. Happy to see that I wasnt wasting my time imaging these.
The active galactic nucleus of M81 contains a supermassive black hole with a mass of 70 million solar masses, or 15 times the mass of the black hole at the centre of the Milky Way. Messier 81 has two well resolved spiral arms that contain large quantities of interstellar dust, associated with numerous starburst regions. Images of M81 taken at infrared wavelengths by the Spitzer Space Telescope have revealed that the interstellar dust is responsible for most of the infrared emissions detected in the galaxy. The hot, young, blue stars in the star forming regions of M81 heat the dust, increasing the emissions from these regions.
Several other members of the M81 Group, including the Cigar Galaxy (M82), are located in the same region of the sky. The Cigar Galaxy can be seen 38 arc minutes north of M81 (just below it in this image). The two galaxies can easily be seen in binoculars and small telescopes, but are not visible to the naked eye. M82 is smaller and fainter than M81, but is a wonderful example of a starburst galaxy and the two make a popular pair among astronomers. NGC 3077 (The Garland Galaxy)can be seen in the upper left part of the image.
I hope you enjoy this image of my first galaxy. Cheers!
The first thing that struck me as I began to see this image unfold is the vast number of stars found in the illuminated sky. Varying temperatures are seen in the gases with hot Hydrogen gases glowing in reddish hues with cooler gases expanding outward.
IC 2177 is a region of nebulosity that lies along the border between the constellations Monoceros and Canis Major. The name Seagull Nebula is sometimes applied by astronomers to this emission region as it resembles a gull in flight, although it also includes the neighboring regions of star clusters, dust clouds and reflection nebulae.
Astronomers catalog the nebula as IC 2177. This cosmic cloud is one of many sites of star formation within the Milky Way galaxy. It is located 3,800 light-years away from Earth, inside the Orion spur — the same partial spiral arm of the Milky Way where our solar system is located. The nebula is nearly 240 light-years across.
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. Astronomers list the region near the seagull’s eye (or lizard’s hip) as NGC 2327, which contains a cluster of stars born about 1.5 million years ago. The eye is the brightest and hottest of the newborn stars in the entire nebula, and heats up the dust so that it glows in infrared light.
Dominated by the reddish glow of atomic hydrogen, the complex of gas and dust clouds with bright young stars spans over 100 light-years at an estimated 3,800 light-year distance.
This image consists of 11 hours of exposures with an ASI071MC pro OSC camera connected to a WO Z73 doublet refractor telescope riding a SW EQ6r Pro mount. Image acquisition with APT, processing in PixInsight.
The Monkey Head Nebula (also known as NGC 2174 and Sharpless Sh2-252) is a star-forming region located 6,400 light-years away in the constellation Orion in which bright, newborn stars near the center of the nebula illuminate the surrounding gas with energetic radiation. The nebula is mostly composed of hydrogen gas. The cloud is sculpted by ultraviolet light carving into the cool hydrogen gas and dust. As the interstellar dust particles are warmed from the radiation from the stars in the center of the nebula, they heat up and begin to glow at infrared wavelengths.
The prime source of energy in the nebula is the massive, hot star named HD 42088. This star has a mass 30 times that of our Sun and a surface temperature 6 times greater. Such stars emit extraordinary amounts of ultraviolet radiation. The high-energy particles in these stars’ outer atmospheres are being blown away in high-speed “stellar winds.”
The ultraviolet radiation causes the nebula to shine. In combination with the stellar wind, this radiation also causes the nebula to expand. Dust and gas are being evaporated and scattered by the energy from the hot star. Where there is a very dense condensation, a pillar is formed pointing toward the star, because the knot shields the material behind it.
If the knot is dense enough, rather than scattering, it may be pushed to collapse into a new star. Such an event is occurring in a pillar above center right of the image. This cannot be seen in visible light, because those wavelengths are blocked by the pillar’s dust. The new star will eventually shed its dusty cocoon and emerge to be seen in optical wavelengths.
This image was captured January 22nd and 23rd 2021 and is made up of 163 240s subs. It was taken with an ASI071MC Pro camera, with OPT Radian Quad Ultra filter, attached to a WO Z73 refractor telescope riding a SkyWatcher EQ6r Pro mount. Guding via a WO 50mm guidescope and ASI120mm mini camera. Pegasus PBA provides power distribution and USB connectivity. QHY Polemaster for precise polar alignment. Senso Sesto electronic focuser.
Flame and Horsehead Nebula in the Orion Molecular Cloud
The Orion Molecular Cloud Complex is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year. This means that astrophotographers all over the world are able to share their images of the areas targets including this Flame, Horsehead, Orion, Running Man and De Marian’s Nebula among others. Here in the northern hemispehere its a winter target. Clear cold nights allow for stunning images.
This image captures several distinct items. The Flame Nebula, designated as NGC 2024 and Sh2-277, is an emission nebula situated just next to the very bright star Alnitak. It is about 900 to 1,500 light-years away. That bright star Alnitak (ζ Ori), the easternmost star in the Belt of Orion, shines energetic ultraviolet light into the Flame and this knocks electrons away from the great clouds of hydrogen gas that reside there. Much of the glow results when the electrons and ionized hydrogen recombine. Additional dark gas and dust lies in front of the bright part of the nebula and this is what causes the dark network that appears in the center of the glowing gas. In this center is a concentrated cluster of newly formed stars.
The Flame Nebula is part of the Orion Molecular Cloud Complex, a star-forming region that includes the famous Horsehead Nebula. The Horsehead Nebula (also known as Barnard 33) is a small dark nebula in the constellation Orion. The nebula is located just to the south of that bright star, Alnitak, the easternmost star of Orion’s Belt within the Orion Molecular Cloud Complex. It appears within the southern region of the dense dust cloud known as Lynds 1630, along the edge of the much larger, active star-forming H II region called IC 434, which is the backdrop of the Horsehead.
The Horsehead Nebula is approximately 422 parsecs or 1,375 light-years from Earth. It is one of the most identifiable nebulae because of its resemblance to a horse’s head. The nebula was first recorded in 1888 by Scottish astronomer Williamina Fleming on a photographic plate taken at the Harvard College Observatory. One of the first descriptions was made by E. E. Barnard, describing it as: “Dark mass, diam. 4′, on nebulous strip extending south from ζ Orionis”, cataloguing the dark nebula as Barnard 33 The dark cloud of dust and gas is a region in the Orion Molecular Cloud Complex where star formation is taking place.
Colour images reveal a deep-red colour that originates from ionised hydrogen gas (Hα) predominantly behind the nebula, and caused by the nearby bright star Sigma Orionis. Magnetic fields channel the gases, leaving the nebula into streams, shown as foreground streaks against the background glow. A glowing strip of hydrogen gas marks the edge of the enormous cloud, and the densities of nearby stars are noticeably different on either side.
Heavy concentrations of dust in the Horsehead Nebula region and neighbouring Orion Nebula are localized into interstellar clouds, resulting in alternating sections of nearly complete opacity and transparency. The darkness of the Horsehead is caused mostly by thick dust blocking the light of stars behind it. The lower part of the Horsehead’s neck casts a shadow to the left. The visible dark nebula emerging from the gaseous complex is an active site of the formation of “low-mass” stars. Bright spots in the Horsehead Nebula’s base are young stars just in the process of forming.
