The Propeller Nebula
Image Description and Details : This cosmic landscape features a often overlooken object in the amateur astronomy community, Simeis 57. It’s nicknamed as the Propeller Nebula. I imaged this nebulosity on multiple nights during September and October between brief gaps in the clouds, acquiring a total exposure time of 14 hours with narrowband filters + RGB for the stars.
Most amateur astronomers use designation DWB 111 for the "Propeller" but it is incorrect as it is only a designation for the southern arm of the object. Designation DWB 119 is used for the northern arm. In 1950s Crimean Astrophysical Observatory at Simeiz, Ukraine designated this object as Simeis 57 in their catalogue of 306 objects of HII regions.
Ten years later the DWB catalog was created by H. R. Dickel, H. Wendker, and J. H. Bieritz. This catalog was intended for HII regions in the Cygnus X complex that they were studying in 1960s. Distance of this nebulosity is unknown but in general the objects in the Cygnus X complex are about 4600 light-years away.

M 34
Image Description and Details :
Messier 34 (also known as M34 or NGC 1039) is a large open cluster located in the constellation of Perseus. It was probably discovered by Giovanni Batista Hodierna before 1654 and included by Charles Messier in his catalog of comet-like objects in 1764. Messier described it as "A cluster of small stars a little below the parallel of γ (Andromedae). In an ordinary telescope of 3 feet one can distinguish the stars. "
M34 is 1500 light years away from us and includes stars of mass between 0.12 and 1 solar mass. It extends for about 35 'into the firmament, which translates into a real radius of 7.5 light years at the distance at which it is located. The cluster is barely visible to the naked eye in very dark conditions, well away from city lights and can be seen through binoculars when light pollution is low.
The age of this cluster is between that of the Pleiades (100 million years) and that of the Hyades (800 million years). In particular, the comparison between known stellar spectra and predicted values from stellar evolutionary models suggest 200-250 million years.

A calm night
Image Description and Details : Reflections here in Kilpisjärvi are quite rare due to strong winds, but that night in october I was lucky with calm weather. The auroras weren't that big, but had some nice colors. The saana mountain (1029m) in the background is one of the tallest and well-known in Finland.

LDN1355
Image Description and Details :
Nebula LDN 1355
Located in the constellation of Cassiopeia,
These dark nebulae lurk in the stellar lairs of the Milky Way. They often connect with the sites of low-mass star formation, but can also float in the arms of the Milky Way as simple cold molecular clouds. They do not have their own light in the visible range and are more recognizable by obscuring more distant stars. And if the astrophoto is taken with long exposure, its brownish color can be seen in the light of nearby stars.
The Helping Hand Nebula is seen toward the constellation Cassiopeia. The shape of the dust cloud darkens in the light of nearby stars, either with a bluish light or sometimes with a yellowish light, but we mainly see its brownish hue.

Barnard 150 the Seahorse Nebula
Image Description and Details : My latest astro project is Barnard 150. A dark nebula in the constellation of Cepheus. Also known as the Seahorse nebula. A dark nebula (absorption nebula), is a dense interstellar cloud that obscures the light from objects behind it, such as background stars and emission or reflection nebulae. Interstellar dust grains located in the coldest, densest parts of larger molecular clouds cause light extinction.

The Grus Quartet of Galaxies
Image Description:
Here reveals only three of its four members in the constellation of The Crane.
Located about 60,000,000 light-years from Earth, this beautiful group of spiral galaxies is gravitationally bound.
At top-right is NGC 7582, a Seyfert Type-2 galaxy, exhibiting lots of star birth. At left is NGC 7599, with NGC 7590 at center.
The missing member of the quartet is NGC 7552, which is another 'starburst' galaxy. The elliptical galaxy, PGC 71043 is at 6 o'clock.
Many thanks to my collaborator and friend, Mike Selby, who acquired and calibrated this fine data from Observatorio El Sauce, Chile.

NGC 7635: A bubble between clouds
Image Description and Details : My last image is a Bubble nebula (NGC 7635) with SHO narrowband channel and added RGB stars.
It is an emission nebula located in the constellation of Cassiopeia. The central bubble is one of three layers of hot gas surrounding the star SAO 20575, a very hot O6.5-class star. Curiously, this star (which is the one that heats the gas so that it emits light), due to its rapid movement, is not in the geometric center of the bubble. It is seen in the lower left area of the center of the bubble. It is a very young star (about 4 million years old...) and is expected to explode as a supernova in about 15 million years (more or less a million...). Interestingly, this nebula is located in a region where another supernova has already exploded.
It's great a lot of signal of SII, and aprecciate a large structures between bubble.

Pleiades (M45)
Image Description and Details : Pleiades (M45)
Open Star Cluster
Magnitude: 1.6
Distance: 444 ly
Constellation: Taurus the Bull
A beautiful and mesmerizing deep sky objects that is etched on several folklores and mythology. This open star cluster is dominated by hot luminous B-Type stars that formed a 100 million years ago and is not gravitationally bound that will eventually drift apart. Pleiades stars are passing through a dust cloud and is completely unrelated reflection nebula. Scientist has found over a 1000 stars in the region. Pleiades is easy to find visually and is also a reference object in finding other deepsky targets.

WHTZ 1
Image Description and Details : WHTZ1 is an obscure, very faint but complex high-excitation planetary nebula in Aquila. It has a size of 193 arc seconds.
It was discovered by Ronald Weinberger, Herbert Hartl, Sonia Temporin and Caterina Zanin in 1999. It was also independently discovered by the French amateur astronomer Thierry Raffaelli in 2014 and is also known as Ra 7. It has also been discovered on two further separate occasions by the Deep Sky Hunters members Dana Patchick and Matthias Kronberger. The limb brightening visible towards its northern edge suggests interaction with the interstellar medium.
This is only the second time that it has been imaged - the previous image by the CHART32 team.

Pacman Revealed
Image Description and Details : NGC 281 - This awe inspiring emission nebula in Cassiopeia contains an open cluster accompanied with several Bok globules that appear to swim in a cosmic ocean rich in molecular hydrogen, sulfur and oxygen. Captured over several nights throughout late August and early September, more than 21 hours of the very best 12 minute subs were selected to reveal the exquisite detail in this mesmerizing region of the night sky.
Last year, I watched James Negri on the DSO Imager channel process this image. I was so impressed with James's image that I decided to add the Pacman Nebula to my list of objects to capture in 2022. The data was surprisingly clean and bright which was a pleasure to process.

OU4
Image Details:
so here's my latest take, it's SH2-129 - OU4, known as:
- SH2-129 Bat Nebula in flight and
- OU4 giant squid nebula, discovered by French amateur astronomer Nicolas Outters.
- For this treatment, I wanted to keep some transparency from the squid, allowing the gases in the background to be distinguished, which gives a sense of depth.
- I also preferred a gentle treatment on the whole Squid to avoid a cupboard thing in the picture as well.

Ngc 1097
NGC 1097 is a barred spiral galaxy 50 million light years away in Fornax.
There are a number of interesting features
The galaxy contains a super massive black hole 140 million times greater than our sun. The black hole is surrounded by a ring with numerous areas of star formation. The ring is lit by an influx of material moving towards the central bar of the galaxy.
The galaxy contains four optical jets (one of which is extremely faint) that seem to emanate from the nucleus region. Studies have determined the jets are not emissions but are made up of stars.
There are two satellite galaxies NGC 1097 A and B. A is a peculiar galaxy which is orbiting only 42000 light years from the center of NGC 1097 while B is a dwarf galaxy which was discovered by emissions and has not been well studied.
