Every day our eyes catch the light of our memories – time spent with family, the journey to work, a special holiday, a beautiful sunset or a dark starlit night. Each image captured is a picture drawn in light – a photograph: only to be lost in our minds or forever forgotten. Nearly two hundred years ago a small group of amateur scientists achieved what had eluded mankind for centuries – the ability to capture a permanent record of an image seen by their own eyes – a moment in time frozen onto a surface. They had discovered Photography. They were the ‘Catchers of the Light’.

The Wizard Nebula


The Wizard Nebula is an emission nebula that surrounds the open star cluster NGC 7380 in the constellation Cepheus. The nebula is known for its unique shape, resembling the appearance of a medieval sorcerer. The active star forming region lies at a distance of 7,200 light years from Earth and has an apparent magnitude of 7.2. It has a radius of 100 light years and occupies 25 arc minutes of the apparent sky. It has the designation Sh2-142 in the Sharpless catalog of H II regions.

Emission Nebula NGC6820 with Open Cluster NGC6823


NGC 6820 is an emission nebula that surrounds open cluster NGC 6823 in Vulpecula, near M27, the Dumbbell Nebula. The nebula NGC 6820 is also called Sharpless catalog Sh 2-86.

The most striking feature is the trunk-like pillar of dust and gas protruding from the east side of the nebula towards the open cluster, NGC 6823 in the west. The center of the open cluster is about two million years old and is predominantly represented by many young, bright blue stars. Outer parts of the cluster intimately involving pillars of emission nebula NGC 6820, contain even younger stars. The huge pillars of gas and dust are probably formed when surrounding gas and dust is pushed and eroded away by radiation from nearby stars. Remarkable dark globules of gas and dust are also visible in the nebula, much as is seen in the better known Eagle Nebula in Serpens or the Lagoon Nebula in Sagittarius.
Open star cluster NGC 6823 is about 50 light years across and lies about 6000 light years away

IC 1795 SHO


IC 1795 is an emission nebula located about 6,000 light-years away in the constellation Cassiopeia.
The dominant central star of IC 1795 is a blue dwarf on the main sequence. In addition there are three other stars of class O and B with ages between 3 and 5 million years. This being an age intermediate to the 6 to 20 million years of the shell structure that encloses the complex. The region is one of the sites most studied (besides Orion) for the formation of massive stars. This area is more dense and rich in H II. It is home to, and hides, a group of young blue stars, with their radiation ionizing the residual gas clouds. (WIKI).

The Cave Nebula


The Cave Nebula ( Sharpless 2-155, Caldwell 9) is part of an extensive region of ionized hydrogen gas region. Sharpless 2-155 is a dim and very diffuse nebula within a larger nebula complex containing emission, reflection, and dark nebulosity. It is located in the constellation Cepheus and associated with the Cepheus B giant molecular cloud, laying at a distance of about 2800 light-years. Part of the cloud is illuminated by a pack of hot, young stars known as the Cepheus OB3 association.

Cave Nebula , the wild beauty of black and white


S 155, also known as the Cave Nebula, Sh2-155 or Caldwell 9, is a dim and very diffuse bright nebula within a larger nebula complex containing emission, reflection, and dark nebulosity. It is located in the constellation Cepheus.

Visually it is a difficult object, but with adequate exposure, makes a striking image. The nebula gets its name Cave Nebula from the dark lane at the eastern side abutting the brightest curve of emission nebulosity which gives the appearance of a deep cave when seen through a telescope visually.

M20 Trifid Nebula in narrowband





The Trifid Nebula (catalogued as Messier 20 or M20 and as NGC 6514) is an H II region located in Sagittarius. It was discovered by Charles Messier on June 5, 1764.[3] Its name means 'divided into three lobes'. The object is an unusual combination of an open cluster of stars; an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (the apparent 'gaps' within the emission nebula that cause the trifurcated appearance; these are also designated Barnard 85). Viewed through a small telescope, the Trifid Nebula is a bright and peculiar object, and is thus a perennial favorite of amateur astronomers.

IC 410 The Tadpoles



IC 410 an emission nebula about 12,000 light-years from Earth in the constellation Auriga. Near the center of the nebulous region is a star cluster ( NGC 1893) and just to the bottom left of this cluster lies two structures that resemble tadpoles. These structures are made of leftover hydrogen and dust from the formation of the star cluster and the "tails" are from the solar wind coming from the stars of NGC 1893.

SH2-115 and Berkeley 90 Ha light


Sharpless 115 stands just north and west of Deneb. Noted in the 1959 catalog by astronomer Stewart Sharpless (as Sh2-115) the faint but lovely emission nebula lies along the edge of one of the outer Milky Way's giant molecular clouds, about 7,500 light-years away. Shining with the light of ionized atoms of hydrogen, sulfur, and oxygen in this Hubble palette color composite image, the nebular glow is powered by hot stars in star cluster Berkeley 90. The cluster stars are likely only 100 million years old or so and are still embedded in Sharpless 115. But the stars' strong winds and radiation have cleared away much of their dusty, natal cloud. At the emission nebula's estimated distance, this cosmic close-up spans just under 100 light-years.

SH2-115 and Berkeley 90 _ Re


Completely new processed.

Sh2-115 proved much more difficult target than i originally thought.
For collecting the photons i wanted , i had to face extremely bad atmospheric conditions, such as high humidity and temperature, in all 5 nights that needed for completion the whole project.
It is a beautiful object but very faint particulary in OIII and SII with complex structures.

Hope you like it ...!

The Rosette Nebula is a large, circular H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter.
The cluster and nebula lie at a distance of some 5,200 light years from Earth (although estimates of the distance vary considerably) and measure roughly 130 light years in diameter. The radiation from the young stars excite the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses.
It is believed that stellar winds from a group of O and B stars are exerting pressure on interstellar clouds to cause compression, followed by star formation in the nebula. This star formation is currently still ongoing.
A survey of the nebula with the Chandra X-ray Observatory in 2001 has revealed the presence of very hot, young stars at the core of the Rosette Nebula. These stars have heated the surrounding gas to a temperature in the order of 6 million kelvins causing them to emit copious amounts of X-rays.

M17 in Ha light


The Omega Nebula, also known as the Swan Nebula, Checkmark Nebula, Lobster Nebula, and the Horseshoe Nebula[1][2] (catalogued as Messier 17 or M17 and as NGC 6618) is an H II region in the constellationSagittarius. It was discovered by Philippe Loys de Chéseaux in 1745. Charles Messier catalogued it in 1764. It is located in the rich starfields of the Sagittarius area of the Milky Way.

The Omega Nebula is between 5,000 and 6,000 light-years from Earth and it spans some 15 light-years in diameter. The cloud of interstellar matter of which this nebula is a part is roughly 40 light-years in diameter and has a mass of 30,000 solar masses.[3] The total mass of the Omega Nebula is an estimated 800 solar masses.It is considered one of the brightest and most massive star-forming regions of our galaxy.An open cluster of 35 stars lies embedded in the nebulosity and causes the gases of the nebula to shine due to radiation from these hot, young stars; however the actual number of stars in the nebula is much higher - up to 800, 100 of spectral type earlier than B9, and 9 of spectral type O,plus >1000 stars in formation on its outer regions.

This is an early version in Ha light only.
