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 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.

This is a combination of my Ha data as a base luminance, about 6 hours of 36 frames 600 sec each, with Irving's data .

Many thanks to Irving for SII,OIII and Ha data of IC410.

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 ...!

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.
