SH 2-275 / Rosette Nebula
The Rosette Nebula, also known as Caldwell 49, is a large HII region located some 4700 light-years from the solar system. It was discovered by the American astronomer Lewis Swift in 1865.
The mass of the Rosette Nebula is estimated to be about 10 000 times the mass of the Sun

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！

NGC 1491 is called the Fossil Footprint Nebula. It is a bright emission nebula and hydrogen (HII) region, located on the edge of a vast cloud region of neutral gas, about 10,700 light-years away in the Perseus arm of our Milky Way Galaxy in the constellation Perseus.
HII regions are well known for being places where new stars are born, and are created when ultraviolet radiation from hot stars ionizes the surrounding gas, causing it to glow in visible light. The surrounding dust is also heated by this radiation, so we also see it glow in infrared light.
The bright, blue star near the centre is illuminating the nebula while its strong stellar wind is “blowing” a bubble in the gas that immediately surrounds it. The intense radiation from the star is also eroding the gas clouds surrounding it.
The entire nebula is quite irregular with a subtle bite cut out of the nebulosity that creates a darker hollow, and a high surface brightness region as seen in this image. A faint, elongated haze extends from this patch past the star, giving an elongated appearance.

The Large Magellanic Cloud is a lenticular galaxy that is part of the "local group" of galaxies and only 163,000 LY away from Earth. This picture also shows some very active associated star formation regions, including the Tarantula Nebula.
Picture composed from 8 Vaonis Vespera Passengers CovalENS mosaics, merged in AstroPixelProcessor and then post-processed with PixInsight.
On the 4th April 2023 the nearly full moon was casting its light across the sky, but up in the Northern constellation of Cepheus the Iris Nebula was still visible.
Many of the nebulae visible in the night sky are emission nebulae since they are clouds of dust and gas that are hot enough to emit their own radiation and light. The Iris Nebula or NGC 7023, is a reflection nebula. This means that its colour comes from the scattered light of its central star, which lies nestled in the abundant star fields of the constellation Cepheus. Located some 1,400 light-years away from Earth, the Iris Nebula’s glowing gaseous petals stretch roughly 6 light-years across. You can also see extensive streams of brownish dust and gas obscuring the distant stars beyond this nebula.
I managed about two hour on this target in the small hours of the morning before finding myself falling asleep. Stayed awake just long enough to pack up all my gear and in bed by 4:30 am.
There is something wrong with this hobby.

故事說明：
M45，昴宿星團，全天最有名的深空天體之一，肉眼即可見到。星團中間年輕的恆星照亮了周圍的雲氣，由於只距離我們443光年左右，因此相當容易進行拍攝。
評審短評：
越是習以為常的深空天體，越能體現拍攝者在進行深空處裡時對於高亮度的星體與低亮度的星雲之間的調配，於累計2小時左右的曝光，可見作者對於天文攝影修圖的技術底運不低，這份作品可作為一般天文攝影修圖之標準作品。
Despite the light pollution from the bright moon I spent about four hours on this nebulous target before it dipped too low in the sky. The larger, predatory looking nebula is IC 417 and the smaller, brighter nebula is NGC 1931.
This fun pair are sometimes called the Spider and the Fly nebulae.
IC 417 is an emission nebula in the constellation Auriga, lying about 10,000 light years away. The glowing centre of the nebula is energized by the hot, massive blue stars embedded within and it is a hotbed of new star formation.
NGC 1931, the Fly Nebula (towards the top) is an emission and reflection nebula, and has been referred to as a miniature version of the Orion Nebula, as it shares some of the same characteristics.

Western Veil Nebula (Caldwell 34), 06/25/2020
This object is part of a super nova remnant from a star that was 20 times more massive than the sun. When that star blew up some 10,000 to 20,000 years ago, it left behind ionized gas and dust that has expanded to cover an area of the sky roughly 6 times the diameter of the Moon. This picture is only one small part of that explosion.
This night was kind of a last-minute decision. I looked outside and saw clear skies so I quickly setup the gear. It was my first night using some new toys, a new light pollution filter and an Asiair Pro computer. The new equipment worked great but I did have a few issues. I had my gain set to 200 for some reason and the polar alignment was crap. But I think I salvaged the data and the image turned out pretty good.

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.

La Nebulosa Elica o Occhio di Dio (NGC 7293) la quale si trova nella Costellazione dell’Acquario è uno degli esempi più spettacolari di nebulosa planetaria, creata da una stella morente che un tempo era simile al Sole. La nube ha una geometria sorprendentemente complessa, che include filamenti radiali, anelli esterni e addensamenti gassosi di ignota origine. Quando il combustibile necessario per le reazioni di fusione nucleare si esaurisce, le stelle di massa medio-piccola vanno incontro alla fine della loro vita gloriosa, espellendo gli strati gassosi esterni e lasciandosi dietro un nucleo denso e caldo, una nana bianca, Il puntino bianco visibile al centro della nube è proprio la densa nana bianca.

The Owl Cluster is a bright open star cluster located approximately 8,000 light-years away in the northern constellation Cassiopeia. It has the designation NGC 457 in the New General Catalogue and is listed as Caldwell 13 in Sir Patrick Moore’s Caldwell catalogue.
The Owl Cluster is one of the finest telescope targets in the northern sky. It is easy to find because it appears in the region of Cassiopeia’s W. NGC 457 is also popularly known as the E. T. Cluster, Dragonfly Cluster, Kachina Doll Cluster, and Phi Cassiopeiae Cluster. I'll go with Owl Cluster as it is easier to spell.
The brightest members of the Owl Cluster are blue stars which are hot, massive, luminous stars that burn through their supply of fuel quickly and evolve into giants or supergiants within only a few million years. They have very short lives due to their high mass. The most massive of these stars will end their lives as supernovae, while others will cast away their outer layers to form planetary nebulae and slowly fade away as dim white dwarfs.
NGC 457 gets its most common nicknames – the Owl Cluster and the E.T. Cluster – because of two bright stars that appear in the same field. These two stars look like a pair of eyes, while the fainter stars form an outline of an owl - or the popular character E.T. from Steven Spielberg’s 1982 film.
This image was taken by integrating 20 two-minute exposures using my C11 telescope. That is not long for astrophotography, but the camera sensor picks up light from the stars much faster than the faint glow from nebulae.

I imaged the Lagoon nebula on August 1, 2019. At that time, I was using my Olympus camera. AstroPixelProcessor did not process Olympus RAW files, so I processed the image using Startools. APP has since been modified to process Olympus RAW files. On September 23, 2020, I reprocessed the 2019 data using APP, and here is the result.

The Cat’s Eye Nebula is a famous planetary nebula located in the northern constellation Draco. The nebula’s designation in the New General Catalogue is NGC 6543.
The Cat’s Eye is one of the most structurally complex nebulae known. It was formed around 1,000 years ago when a hot, bright central star expelled its outer envelope. It is sometimes also known as the Sunflower Nebula or the Snail Nebula. It lies at a distance of 3,300 light years from Earth.
There is an enormous but exceptionally faint halo of gaseous material surrounding the Cat’s Eye Nebula which is over three light-years across. Within the past years some planetary nebulae been found to have halos like this one, likely formed of material ejected during earlier active episodes in the star’s evolution – most likely some 50,000 to 90,000 years ago.
In my photo the Cat's Eye Nebula is the central, bright area. It is burnt out as I have probably overexposed the images but it means you can see the glow of the surrounding material.
The brightest of the knots in the nebula’s halo has its own entry in the IC catalogue: IC 4677.
Lower down in the image you can see NGC 6552 which is a barred spiral galaxy about 400 million light years from our solar system.
