Messier 66 (M66), the brightest and largest member of the Leo Triplet of galaxies, is an intermediate spiral galaxy located in Leo constellation. The galaxy lies at a distance of about 36 million light years from Earth and has an apparent magnitude of 8.9. It has the designation NGC 3627 in the New General Catalogue.
Messier 66 has a diameter of about 95,000 light years. It can be seen in the same field of view as its neighbours M65 and NGC 3628. M66 is separated from M65 by only 200,000 light years.
The Leo Triplet can be found between the stars Theta and Iota Leonis, or along the line from the bright star Denebola to Regulus, the brightest star in Leo.
In this picture M66 is the leftmost of the two Messier galaxies in the group.
The Leo Triplet is also known as the M66 Group, which consists of M66, M65, NGC 3628 and possibly two other galaxies. M66 is notable for its outstanding dark dust lanes and bright starburst regions along the spiral arms.
Gravitational interaction with the nearby galaxies Messier 65 and NGC 3628 has significantly affected M66. The galaxy’s past encounter with NGC 3628 has resulted in an extremely high central mass concentration, asymmetrical spiral arms and an interstellar cloud composed of neutral atomic hydrogen – removed from one of the galaxy’s spiral arms. As a result, the galaxy appears to have a conspicuous and unusual structure of spiral arms and dust lanes. The distorted, hooked spiral arms appear displaced above the plane of the galaxy’s disk.

With the weather being bad I was able to sit down and work on some stuff. Was able to add another hour of data to my Orion shot and really sit down and make tweaks to it and pull out a lot more data. Still not exactly where I want it to be, but much better overall in my opinion.

Heart Nebula (IC 1805), 08/27/2020
Last weekend I headed back out to the Buck Creek campground, this time by myself. The weather was clear and the moon was not yet full and I couldn’t pass up the opportunity. I was able to setup my big telescope and two separate cameras to capture images. I’ll post the other pictures soon. It was a successful trip all around.
This is the Heart Nebula and it is huge. If the Heart Nebula was as easy to see as the Moon, it would be almost ten times the size in the night sky. It is found in the constellation of Cassiopeia and is some 7500 light-years away. The lower portion of the Heart Nebula has its own designation NGC 896 and is called the Fish head Nebula. It seems to me that these two nebulae where easy to name.

Eagle Nebula (M16), 07/09/2020
We had a new moon and clear skies at the same time last weekend so there was no way I was passing up that opportunity. I hooked up the RV, kissed my wife goodbye, and headed to the hills to catch some photons! Things mostly went well, mostly. As I started to setup my gear at dusk, I realized I had forgotten a critical usb cable. This meant I needed to huck all the expensive equipment into the RV and run into town. This was a two-hour round trip to Wally World and back. Then re-setup the telescope and let it run into the wee hours of the night.
This is the Eagle Nebula, an object I have shot several times before, but this time I used a fancy light pollution filter. This filter makes it possible to process the data in a simulated Hubble Telescope color palette. Short explanation is that the filter separates the hydrogen-alpha (red) and the oxygen-III (blue) light-wavelengths into separate color channels during image processing.
The Eagle Nebula is a 5.5-million-year-old cloud of molecular hydrogen gas and dust stretching approximately 70 light years by 55 light years. It lies about 6,500 light-years away. The “Eagle” itself in the center is the famous Hubble image, “The Pillars of Creation”.

Uranus is the seventh planet in distance from the Sun and the least massive of the solar system’s four giant, or Jovian, planets, which also include Jupiter, Saturn, and Neptune.
Its moons are named after characters created by William Shakespeare and Alexander Pope. These include Oberon, Titania, Umbriel, Ariel and Miranda. All are frozen worlds with dark surfaces. Some are ice and rock mixtures. The most interesting Uranian moon is Miranda; it has ice canyons, terraces, and other strange-looking surface areas.
The bright star to the right is Omicron Arietis in Aries.

Sharpless 2-12 is a very large nebula. It's full extent sprawls over a vast region and it is therefore best imaged with either a smaller focal length or a camera with a bigger sensor or both
Still this view does reveal some interesting structures. Like many Sharpless objects it doesn't seem to be imaged that often

The Sombrero Galaxy (M104), 04/18/2021
Like I said in my last photo, its galaxy season, lol. A few weeks ago, I took my gear up into the woods and was able to capture lots of images while in the dark skis. I have always wanted to photography this galaxy, but it is really small and far away (31 million light-year), but I did it anyways. This picture is cropped in a lot. The Sombrero Galaxy is almost perfectly edge on to our field of view, so the dust lanes really pop. It also contains one of the biggest super-massive black holes ever discovered.

Technical explanation of objects :
The Virgo cluster is a cluster of galaxies located approximately 59 ± 4 million light-years away in the direction of the constellation Virgo. It contains some 1,300 known galaxies, although there may be as many as 2,000, and forms the central region of the Local Supercluster, in which the Local Group is also found. Its mass is estimated to be 1.2×1015 MS up to about 8 degrees from the center of the cluster, which is equivalent to a radius of about 2.2 Mpc.3
Many of the bright galaxies in this cluster, including the giant elliptical galaxy Messier 87, were discovered in the late 1770s and early 1780s and later included in Charles Messier's catalogue. Described by Messier as starless nebulae, their true nature would not be discovered until the 1920s.
The cluster subtends a maximum arc of about 8 degrees centered on the constellation Virgo, and many of its galaxies can be seen with an amateur telescope. Its brightest member is the giant elliptical galaxy M49, but the most notable and famous is the galaxy M87, located in its center.
In the center of the image we show we have NGC 4435 and NGC 4438, also known as the Eye Galaxies or Arp 120, they are two galaxies in the Virgo Cluster, about 52 million light years from our galaxy, also visible with amateur telescopes.
NGC 4435:
NGC 4435 is a barred lenticular galaxy showing a ring of dust around the nucleus. Through studies carried out with the Spitzer telescope, a young stellar population has been detected in its center, which indicates that 190 million years ago it suffered a stellar outbreak perhaps caused by an interaction with NGC 4438, and almost all of its hot gas, according to studies. made in X-rays with the Chandra telescope, is concentrated in its central region. It also seems to have a long tail that was also thought to be produced by this event, but which is actually a system of dust clouds in our galaxy that is totally unrelated to NGC 4435.
NGC 4438:
NGC 4438 is a hard-to-classify galaxy that has been classified as both a spiral galaxy and a lenticular galaxy, which explains its inclusion in Halton C. Arp's Atlas of Peculiar Galaxies. It is one of the most notable galaxies in the cluster due to its highly distorted appearance, which shows that it is undergoing or has undergone gravitational interactions, and for the unknown mechanism that causes its central region to show activity, and that it has expelled opposing gas loops at one the other. A starburst, a black hole, or an active galactic nucleus has been thought of, and all possibilities are under investigation. It also shows a low content of neutral hydrogen, perhaps due to its friction with the hot gas that fills the intergalactic medium of Virgo or with the corona of hot gas that surrounds the nearby galaxy M86 and/or due to having been torn away by gravitational attraction. of some galaxy with which it was about to collide (perhaps M86 itself), in addition to a displacement of the different components of its interstellar medium (neutral hydrogen, molecular hydrogen, hot gas, and interstellar dust, which reaches up to a distance of 4-5 kiloparsecs from its disk) in the direction of NGC 4435 -which tends to be attributed, however, to friction with the aforementioned intergalactic medium-, and finally traces of having undergone several bursts of star formation.
A pair of interacting galaxies?
NGC 4435 and NGC 4438 have been and are considered by numerous authors to be a pair of interacting galaxies, having calculated that the two galaxies came close 100 million years ago to just 16,000 light years from each other. In any case, and despite the strong evidence in favor of an interaction between the two, other scientists have expressed doubts as to whether the two galaxies are actually interacting despite their apparent proximity, since their redshifts are different and NGC 4435 is barely visible. has suffered the effects of such interaction. It has also been speculated that NGC 4438 may actually be two galaxies merging, having nothing to do with NGC 4435, which has interacted in the past with M86 (to which it seems to be joined by filaments of gas and in which it is detected certain amount of interstellar dust and atomic and ionized hydrogen that seems to come from NGC 4438, which reinforces this possibility) causing the peculiarities observed in it, that the three mentioned galaxies have interacted with each other, and even that NGC 4438 may be being torn apart by the gravity (tidal forces) of M87, which is only 58 arcminutes away from it (and seems to have gotten as close as 300 kiloparsecs).

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 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. 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. [Courtesy of Wikipedia en.wikipedia.org/wiki/Crescent_Nebula ]
I don't have a UHC or OIII filter so I just used my UV/IR Cut filter. Being near Sadr, it is close to the centre of the Milky Way which is why the image is flooded with stars. Definition is lost on the stars at the edges since I don't have the Edge HD version of the C11. It costs about three times more than the scope I have.

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 central part 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 which lies near its centre.
This image is from integrating nearly two hours worth of two minute exposures using my ZenithStar 81 telescope. If there had not been so many clouds I would have been able to collect four or five hours of data which would have made the image even sharper and more detailed.

This is my second image of B33, the Horsehead Nebula; the earlier one can be found below.
This image can be thought of as a "closeup" of the Horsehead. It was obtained with a scope with a focal length of 1860 mm; the earlier pic was obtained with a scope with half that focal length, 900 mm.
The Horsehead is a vast and dense cloud of dust, behind which is a vast, red emission nebula., IC 434. To the lower left of the Horsehead is a blue reflection nebula known as NGC 2023. The Horsehead is about 1500 light years away.
All of these objects are part of a region known as the Orion B molecular cloud, a star-forming region in the Milky Way.

I liked the look that my Seestar got of M104, the Sombrero Galaxy so I took a closer look with my C11 last night for about three and a half hours.
The Sombrero Galaxy, also known as Messier 104 (M104), is a famous unbarred spiral galaxy. It lies at a distance of 29.3 million light years from Earth in the direction of the constellation Virgo.
The Sombrero Galaxy is known for its appearance, similar to that of a Mexican hat, with a bright white core surrounded by thick lanes of dust and a halo of globular clusters and stars. The galaxy appears almost exactly edge-on when observed from Earth.
There is a supermassive black hole at the heart of the Sombrero Galaxy. It is one of the most massive black holes detected in galaxies near the Milky Way. It is believed to have a mass of at least a billion suns. This would make it about 250 times larger than the black hole in the centre of our galaxy, the Milky Way.

It was clear last night so I was able to set up my C11, spend several hours setting up the mount and the scope, faffing about with focus and guiding and calibration frames and all that sort of guff.
Then I pointed at M92, a globular cluster of stars in the constellation of Hercules. A grand sight. For all of 15 minutes before the clouds rolled in. Oh well. At least I got enough data to build this image.
The cluster lies at a distance of 26,700 light years from Earth and has an estimated mass of up to 330,000 solar masses. With an estimated age of 14.2 billion years – almost the same age as the universe itself – M92 is one of the oldest clusters known and possibly the single oldest globular in the Milky Way

Heart Nebula (IC-1805), 07/10/2021
So on the second night of my last camping adventure to catch starlight I shot the Heart Nebula on a whim. Again, I have done this a few times before, but it was in a good location in the sky, and I wanted to try my new processing techniques on this one as well. This night went way easier than the night before and I was able to get some great data. It may be my favorite image to date and I’m pretty sure I will be making a big print for my wall.
The Heart Nebula is found in the constellation of Cassiopeia and is some 7500 light-years away. If you could see it with the naked eye, it would be almost ten times the size of the full moon in the night sky. The lower portion of the Heart Nebula has its own designation NGC 896 and is called the Fish Head Nebula.

The Deer Lick Galaxy Group is really only a visual grouping of galaxies in the constellation Pegasus.
The large, spiral galaxy NGC 7331 in the centre of this picture is a foreground galaxy in the same field of view as the collection known as the Deer Lick Group. It contains four other members, affectionately referred to as the "fleas": the lenticular or unbarred spirals NGC 7335 and NGC 7336, the barred spiral galaxy NGC 7337 and the elliptical galaxy NGC 7340. These galaxies lie at distances of approximately 332, 365, 348 and 294 million light years, respectively.
Although adjacent on the sky, this collection is not a galaxy group, as NGC 7331 itself is not gravitationally associated with the far more distant "fleas"; indeed, even they are separated by far more than the normal distances (~2 million light years) of a galaxy group.
Even so, it is nice to be able to capture so many galaxies in one shot.

From my October, 2019 trip to Cosmic Campground. New Mexico. 30 x 3 minute exposures with ASI294 camera; SV80 Access on Losmandy GM811G mount. Processed with Astropixelprocessor with tweaks from Startools and ACDSee.
Compare with the image from earlier this summer with a different camera (Olympus OMD-EM1 Mark ii). The ASI pretty well blows the Olympus away--not surprisingly, because the ASI is a dedicated astrocamera and the Oly isn't.

故事說明：
SH2-275，玫瑰星雲，在全國大學天文聯盟儀器營隊的時候做拍攝，中心玫瑰的左上角可以看到淡淡的一條星雲，常常被當作為玫瑰的枝；而除了玫瑰星雲這名稱外，從現在的角度看，可以發現他貌似一個骷髏頭，因此也有人稱他為骷髏頭星雲。
評審短評：
作品對曝光累積時間不錯。唯獨色彩與高動態掌握上還有進步空間，色階與暗空背景的過渡稍微僵硬,建議可以使用多重曝光或窄頻,豐富這一區域的影像！

At the end of my stargazing session last night there was still a bit of dark sky remaining so I spent about three quarters of an hour on Messier 29.
M29, also known as NGC 6913, is sometimes called the Cooling Tower Cluster. It is a quite small, bright open cluster of stars just south of the central bright star Gamma Cygni in the constellation of Cygnus, the Swan.
I didn't have to spend hours capturing faint wisps of galactic spiral arms or fetching the folds and details of a nebula because the stars show up quickly against the dark sky.

The Fishhead nebula (NGC 896 / IC 795) is an emission nebula in the constellation Cassiopeia. A star forming region, the intense red colour comes from hydrogen photon emissions. Also visible in this nebula are dark lanes of obscuring dust. The nebula is approximately 6000 light years distant. The brighter region of the nebula is catalogued as NGC 896.
This nebula is a part of a much larger complex of nebulosity including the Heart Nebula (IC 1805).

Messier 53 (M53) is a globular star cluster located in the northern constellation Coma Berenices. The cluster is almost 60,000 light years from Earth. It contains at least 500,000 stars.
The stars in the cluster are considered metal-poor, as they contain very little quantities of elements heavier than helium, which is below average for stars found in a globular cluster.

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 Alnitak, the easternmost star of Orion's Belt, and is part of the much larger 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 you can see in the bottom left corner of this image
The Horsehead Nebula is approximately 1,400 light-years from Earth. It is one of the most identifiable nebulae because of its resemblance to a horse's head.

On the first clear night in a month I had two hours to capture something so I focussed on what I call the Brighton and Hove Albion Nebula (aka the Seagulls).
It is a broad expanse of glowing gas and dust presenting a bird-like appearance, hence its more common name - The Seagull Nebula. You can just about make out the wings and body. If I had more time they would have been more distinct.
The cloud of gas at the ‘head’ of the Seagull (Sharpless 2-292) glows brightly due to the energetic radiation from an extremely hot young star within it (HD 53367).
Sharpless 292, IC 2177, and NGC 2327 all refer to the ‘head’ of the Seagull, which is only a small portion of the larger nebula. The entire nebula region spans nearly 240 light-years across.
The picture also includes two open clusters of stars. NGC 2335 is about a third of the way up on the left and NGC 2343 is in the centre at the bottom of the picture. There are so many other stars here it may be hard to tell what is a cluster and what isn't.
