The Eagle Nebula (catalogued as Messier 16 or M16, and as NGC 6611, and also known as the Star Queen Nebula and The Spire) is a young open cluster of stars in the constellation Serpens, discovered by Jean-Philippe de Cheseaux in 1745–46. Both the "Eagle" and the "Star Queen" refer to visual impressions of the dark silhouette near the center of the nebula,[3][4] an area made famous as the "Pillars of Creation" imaged by the Hubble Space Telescope. The nebula contains several active star-forming gas and dust regions, including the aforementioned Pillars of Creation. The Eagle Nebula lies in the Sagittarius Arm of the Milky Way.

This was a turn out for the books after today's hailstorms. Hoping for clear skies tomorrow to see this Skywatchers will be treated to a “once in a lifetime” event on December 21, 2020. In what is known as a Great Conjunction of Jupiter and Saturn, these two planets will be closer in the night sky than at any other point in time since 1623. The conjunction that year was not visible to most of the Earth due to its position in the sky, being too close to the sun to be seen clearly. The last time that a similar conjunction of Jupiter and Saturn was clearly visible to most of the planet was in 1226.
With their close proximity, these planets are predicted to appear to the naked eye as a single (and very bright) star, reminiscent of the Star of Bethlehem (Christmas star) described in the Bible as leading the three Wise Men to the town of Bethlehem. Johannes Kepler theorized that a similar conjunction may have been the origin of the Biblical descriptions of that exceptionally bright star. The Christmas star effect is expected to be visible for the entire fourth week of December, but Jupiter and Saturn will be at their brightest on December 21st due to their positions in the sky that night .

This is the latest series of data captured and processed over 5 nights from GrandMesaObservatory.com in Purdy Mesa Western Colorado using the Sky-Watcher Esprit 150mm ED F7.0 Triplet APO Refractor courtesy of Sky-Watcher USA.
The data is from “System 2” and available through Grand Mesa Observatory’s Subscription services which you can read more about here: grandmesaobservatory.com/equipment-rentals
The 2 renderings in Hubble Palette (SHO) and the more natural LRGB with H-Alpha and OIII were assembled and processed in Photoshop CC, we acquired the data using the QHY163M Monochrome CMOS and all 7 filters LRGB and Narrowband Ha, OIII and SII Filters by Optolong
In the Hubble Palette version the H-Alpha is mapped to Green, SII is mapped to Red and OIII is mapped to Blue and I used the natural stars from LRGB. With the LRGB version H-Alpha is mapped to red and OIII mapped to blue.
57 individual frames make up these images having a total Integration time of 12.8 hours

The Crescent Nebula, located near the middle star that marks the heart of the constellation Cygnus, is a complex arc of gas that’s powered by the machinations of a massive dying star. Called WR 136, this star is just 4-5 million years old, but it’s big enough to have quickly burned through its store of fuel in its core and has now entered a stage where it sheds mass from its outer layer at a prodigious rate, nearly one full solar mass every 10,000 years. This fast-moving hot gas, which moves at a speed of 2,000-3,000 km/s, collides with cooler gas ejected by the star during its quieter days, and the collision excites the gas to emit light. Massive and mass-losing stars like WR 136 are called Wolf-Rayet stars. There are only about 150 such stars known in the Milky Way.
WR 136 will eventually detonate as a supernova when it finally runs of fuel and collapses. The explosion will obliterate the nebula and most other material within several dozen light years of the star. In its place will be a new type of nebula called a “supernova remnant” that consists of a rapidly expanding shock wave that excite the scant atoms lingering in the interstellar medium.
The location of the Crescent Nebula near the star Sadr in the constellation Cygnus, spread out over about 25 light years and lies at a distant 4,700 light years. It’s sometimes called the “Euro” nebula because of its resemblance to the symbol for the currency.

Object description (wikipedia.org):
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. 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 west of IC 1396A. (In the Figure above, the massive star is just to the left of the edge of the image.) 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.

Once I could get the best results throughout the Moon's disk I joined two shots with the same data, one about two thirds north-south of the disk and another covering the rest.
I edited and joined them with Photofiltre and MS Picture Manager, to get more details.
