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.[1] 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. 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.

The Elephant's Trunk Nebula is now thought to be a site of star formation, containing several very young (less than 100,000 yr) stars that were discovered in infrared images in 2003. Two older (but still young, a couple of million years, by the standards of stars, which live for billions of years) stars are present in a small, circular cavity in the head of the globule. Winds from these young stars may have emptied the cavity.

The combined action of the light from the massive star ionizing and compressing the rim of the cloud, and the wind from the young stars shifting gas from the center outward lead to very high compression in the Elephant's Trunk Nebula. This pressure has triggered the current generation of protostars.

PS I actually named this object in May 2009, way back when I first imaged it and found no amateur photos on the internet. And I still think the name is apt!

Comet C/2022 E3 ZTF. This is a reprocessing of an image taken of the comet in early February. The first attempt using just Nebulosity looked a bit messy with traces of star streaks that were not entirely eliminated. The second attempt was done with Deep Sky Staker which yielded a much better result but I preferred the star field from the first attempt so this image is a composite of both.

[From Wikipedia] C/2022 E3 (ZTF) is a long-period comet from the Oort cloud that was discovered by the Zwicky Transient Facility (ZTF) on 2 March 2022. The comet has a bright green glow around its nucleus, due to the effect of sunlight on diatomic carbon and cyanogen. The comet's systematic designation starts with C to indicate that it is not a periodic comet, and "2022 E3" means that it was the third comet to be discovered in the first half of March 2022.

The comet nucleus was estimated to be about a kilometer in size, rotating every 8.5 to 8.7 hours. Its tails of dust and gas extended for millions of kilometers and, during January 2023, an anti-tail was also visible.

The comet reached its perihelion on 12 January 2023, at a distance of 1.11 AU (166 million km; 103 million mi), and the closest approach to Earth was on 1 February 2023, at a distance of 0.28 AU (42 million km; 26 million mi). The comet reached magnitude 5 and was visible with the naked eye under moonless dark skies.

The Orion Nebula (also known as M42) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae and is visible to the naked eye in the night sky. It is 1,344 ± 20 light-years (412.1 ± 6.1 pc) away and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light-years across. It has a mass of about 2,000 times that of the Sun.

M16 (Messier 16) is known as the Eagle Nebula. It is one of the brightest nebulae in the night sky, and is visible in both the northern and southern hemispheres.

The Eagle Nebula is a large cloud of gas and dust where new stars are born. When you look at this nebula you are seeing a stellar object that is approximately 7000 light-years away.

The newborn stars in the Eagle Nebula are very hot, which illuminates M16’s hydrogen gas as seen in the Pillars of Creation image made famous by the Hubble Space Telescope.

Orion now sets so early we had time for another quick target, so here is a pair of galaxies in the constellation Leo, M95 (on the right) and M96 (on the left). Both galaxies are part of the M96 Group.

[Summarised From Wikipedia] Messier 95, also known as M95 or NGC 3351, is a barred spiral galaxy about 33 million light-years away.

Messier 96 (also known as M96 or NGC 3368) is an intermediate, double-barred spiral galaxy about 31 million light-years away. Messier 96 is about the same mass and size as the Milky Way. It is a very asymmetric galaxy; its dust and gas are unevenly spread throughout its weak spiral arms, and its core is just offset from the midpoint of its extremes. Its arms are also asymmetrical, thought to have been influenced by the gravitational pull of other galaxies within its group.

The Triangulum Galaxy is a spiral galaxy 2.73 million light-years from Earth in the constellation Triangulum. It is known as Messier 33 or NGC 598.

I've got around 3 hours of imaging over two different days a month apart with my William Optics FLT91, ZWO ASI2600MC Pro and Optolong L-Pro broadband filter. I would like to get more time on it, but nights are getting cloudy again, so uploading "as is" now and will return to it when I get more clear nights. I think it's already looking good after ~3 hours, so can't wait to get more time on it. Maybe use the L-Enhance filter to get more Ha data.

The Crescent Nebula (NGC 6888) and the surrounding gas and dust clouds in the constellation Cygnus, photographed in H-alpha. This was a 6-pane mosaic created with the aid of Telescopius, a wonderful program. The image spans about 5.2º x 5.3º, so roughly 10 full moons in each direction. Sometimes a bigger bite is better.

NGC 4236

Also known as Caldwell 3, this barred spiral galaxy is in the constellation of Draco. It is approximately 11.7 million light years away( A light year is 5.9 trillion miles)

Swapped my cameras around while it has been cloudy. This was taken with the QHY23M CCD camera on the 11" Hyperstar and the QHY163M CMOS camera on the Orion ED102T. Both are mounted on an Orion HDX-110.

The teal markings on the annotated version are all galaxies.
