Messier 106

Messier 106 (also known as NGC 4258) is an intermediate spiral galaxy in the constellation Canes Venatici. It was discovered by Pierre Méchain in 1781. M106 is at a distance of about 22 to 25 million light-years away from Earth. It is also a Seyfert II galaxy. Due to x-rays and unusual emission lines detected, it is suspected that part of the galaxy is falling into a supermassive black hole in the center. NGC 4217 is a possible companion galaxy of Messier 106. A Type II supernova was observed in this galaxy in May 2014.

Helix Nebula_NGC 7293_Ha 5nm

The Helix Nebula, also known as The Helix, NGC 7293, is a large planetary nebula (PN) located in the constellation Aquarius. Discovered by Karl Ludwig Harding, probably before 1824, this object is one of the closest to the Earth of all the bright planetary nebulae.The estimated distance is about 215 parsecs (700 light-years). It is similar in appearance to the Cat's Eye Nebula and the Ring Nebula, whose size, age, and physical characteristics are similar to the Dumbbell Nebula, varying only in its relative proximity and the appearance from the equatorial viewing angle.

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

M63 Sunflower Galaxy

M63 was discovered by Pierre Méchain on June 14, 1779.[4] The galaxy was then listed by Charles Messier as object 63 in the Messier Catalogue.

In the mid-19th century, Lord Rosse identified spiral structures within the galaxy, making this one of the first galaxies in which such structure was identified.[4]

In 1971, a supernova with a magnitude of 11.8 appeared in one of the arms of M63.

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).

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.

Schroter's Valley

Schroter's Valley, frequently known by the Latinized name Vallis Schröteri, is a sinuous valley or rille on the surface of the near side of the Moon. It is located on a rise of continental ground, sometimes called the Aristarchus plateau, that is surrounded by the Oceanus Procellarum to the south and west and the Mare Imbrium to the northwest. At the southern edge of this rise are the craters Aristarchus and Herodotus.

This is the largest sinuous rille on the Moon. It begins at a 6 km diameter crater located 25 km to the north of Herodotus. (The start of the rille has been termed the "Cobra's Head" by some observers, due to its resemblance to a snake.) From the crater it follows a meandering path, first to the north, then setting a course toward the northeast, before finally bending back to the south until it reaches a 1 km high precipice at the edge of the Oceanus Procellarum. The rille has a maximum width of about 10 km, then gradually narrows to less than a kilometer near its terminus.

The origins of this rille are believed to be volcanic. The interior floor has been resurfaced and is very level. However there is a slender rille located on the floor, which can be photographed from Earth with a good telescope and good seeing.

The rille has been the subject of numerous transient lunar phenomena observations.

The selenographic coordinates of this valley are 26.2°N 50.8°W, and it has a maximum diameter of 168 km. It is named for Johannes H. Schröter.

It was a potential landing site for the canceled Apollo 18 mission

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 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 ...!

Venus

Telescope : Meade LX90 (ota only)
Camera : IS DBK21
Televue Powermate x2,5
Mount: EQ6Pro

Venus is the second planet from the Sun, orbiting it every 224.7 Earth days.[11] It has no natural satellite. It is named after the Roman goddess of love and beauty. After the Moon, it is the brightest natural object in the night sky, reaching an apparent magnitude of −4.6, bright enough to cast shadows.[12] Because Venus is an inferior planet from Earth, it never appears to venture far from the Sun: its elongation reaches a maximum of 47.8°.

Venus is a terrestrial planet and is sometimes called Earth's "sister planet" because of their similar size, mass, proximity to the Sun and bulk composition. However, it has also been shown to be radically different from Earth in other respects. It has the densest atmosphere of the four terrestrial planets, consisting of more than 96% carbon dioxide. The atmospheric pressure at the planet's surface is 92 times that of Earth's. With a mean surface temperature of 735 K (462 °C; 863 °F), Venus is by far the hottest planet in the Solar System, even though Mercury is closer to the Sun. Venus has no carbon cycle that puts carbon into rock, nor does it seem to have any organic life to absorb carbon in biomass. Venus is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light. It may have possessed oceans in the past,[13][14] but these would have vaporized as the temperature rose due to a runaway greenhouse effect.[15] The water has most probably photodissociated, and, because of the lack of a planetary magnetic field, the free hydrogen has been swept into interplanetary space by the solar wind.[16] Venus' surface is a dry desertscape interspersed with slab-like rocks and periodically refreshed by volcanism

C/2014 Q2 (Lovejoy) _15-1-2015

C/2014 Q2 (Lovejoy) is a long-period comet discovered on 17 August 2014 by Terry Lovejoy using a 0.2-meter (8 in) Schmidt–Cassegrain telescope.[1] It was discovered at apparent magnitude 15 in the southernconstellation of Puppis.[1] It is the fifth comet discovered by Terry Lovejoy.

By December 2014, the comet had brightened to roughly magnitude 7.4,[4] making it a small telescope and binoculars target. By mid-December, the comet was visible to the naked eye for experienced observers with dark skies and keen eyesight.[5] On 28−29 December 2014, the comet passed 1/3° from globular cluster Messier 79.[6] In January 2015, it brightened to roughly magnitude 4−5,[7] and became one of the brightest comets located high in a dark sky in years. On 7 January 2015, the comet passed 0.469 AU (70,200,000 km; 43,600,000 mi) from Earth.[8] It crossed the celestial equator on 9 January 2015 becoming better seen from thenorthern hemisphere.[9] The comet will come to perihelion (closest approach to the Sun) on 30 January 2015 at a distance of 1.29 AU (193,000,000 km; 120,000,000 mi) from the Sun.[2]

Before entering the planetary region (epoch 1950), C/2014 Q2 had an orbital period of about 11000 years.[3] After leaving the planetary region (epoch 2050), it will have an orbital period of about 8000 years.[3]

A Cosmic Tale, the W5, a radio source within the Soul nebula

The W5, a radio source within the Soul nebula, spans an area of sky equivalent to four full moons and is about 6,500 light-years away in the constellation Cassiopeia. Like other massive star-forming regions, such as Orion and Carina, W5 contains large cavities that were carved out by radiation and winds from the region's most massive stars. According to the theory of triggered star formation, the carving out of these cavities pushes gas together, causing it to ignite into successive generations of new stars. The image in the gallery above contains some of the best evidence yet for the triggered star formation theory. Scientists analyzing the photo have been able to show that the ages of the stars become progressively and systematically younger with distance from the center of the cavities.

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.

I made a synthetic luminance layer from the whole of my frames. Then I apply about 30 iterations of selective deconvolution in ccdstack. With ''selective'' i mean: manual selection of the area for deconvolution.
And the question is :What is the exposure time in this image ?
the total exposure time is the sum of whole frames and that is or the sum of the separate master layers such as Lum LumSynth RedSynth(Red+Ha) and so on

too many "lies"...in one image, but the result is quite similar to RGB.

SH 2-124 Emission nebula

No, it's not the Trifid nebula , this is the SH2-124,an emission nebula located in the constellation of Cygnus. It is a faint target, rarely imaged.

SH 2-115 and Berkeley 90

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 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 ...!

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.

M16 the Eagle Nebula

The Eagle Nebula (catalogued as Messier 16 or M16, and as NGC 6611, and also known as the Star Queen Nebula) is a young open cluster of stars in the constellation Serpens, discovered by Jean-Philippe de Cheseaux in 1745-46. Its name derives from its shape that is thought to resemble an eagle. It contains several active star-forming gas and dust regions, including the famous "Pillars of Creation", photographed by the Hubble Space Telescope.

M13 GLOBULAR CLUSTER

M13 was discovered by Edmond Halley in 1714, and catalogued by Charles Messier on June 1, 1764.With an apparent magnitude of 5.8, it is barely visible with the naked eye on a very clear night. Its diameter is about 23 arc minutes and it is readily viewable in small telescopes. Nearby is NGC 6207, a 12th magnitude edge-on galaxy that lies 28 arc minutes directly north east. A small galaxy, IC 4617, lies halfway between NGC 6207 and M13, north-northeast of the large globular's center.
M13 is about 145 light-years in diameter, and it is composed of several hundred thousand stars, the brightest of which is the variable starV11 with an apparent magnitude of 11.95. M13 is 25,100 light-years away from Earth.
