The Pinwheel Galaxy (also known as Messier 101, M101 or NGC 5457) is a face-on spiral galaxy 21 million light-years (6.4 megaparsecs) away from Earth in the constellation Ursa Major. It was discovered by Pierre Méchain in 1781 and was communicated that year to Charles Messier, who verified its position for inclusion in the Messier Catalogue as one of its final entries.

Not the best image but I was fairly impressed by the filter, given the price when compared with the L-Extreme.

The Antennae galaxies in Corvus are a pair of colliding spiral galaxies around 50 to 60 million light years away. The collision began 600 million years ago and will conclude in another 400 with the merger of the two galaxies. The faint "antennae" are streams of stars ejected from the galaxies by the collision which has also triggered a starburst formation of new stars.

This image is an RGB integration of data captured on a QHY163M camera with a WO FLT110 scope and Optolong filters. I got approx 10 hours data in each of the colour channels. Image sequencing was managed via SGP and PHD2, all post-processing was done in PixInsight.

IC 1805 is an emission nebula in the northern constellation of Cassiopeia, approximately 7500 light years from earth. The brightest part of the nebula (to the right) is separately classified as NGC 896. The open cluster of stars in the middle of the "heart" is known as Melotte 15.

Also visible in the upper left quadrant is the recently (1995) discovered planetary nebula WeBo 1 (also known as PN G135.6+01.0).

Messier 38 (M38), also known as the Starfish Cluster, is an open star cluster located in the northern constellation Auriga. The cluster lies at a distance of 4,200 light years from Earth and has an apparent magnitude of 7.4, making it invisible to the naked eye but easily identifiable with a pair of binoculars. Nearby, on the top of the image, a smaller cluster - NGC 1907 - can also be seen. These two clusters are unrelated but a 2002 study reveals they are presently in a fly by one by the other.

The shape of the nebula draws the North American continent, especially the east coast, between the Gulf of Mexico and Florida.

The discovery of the North American Nebula is attributed to astronomer William Herschel. Together with the nearby Pellican Nebula, it constitutes a single nebulae complex, located about 1960 light years away, in which star formation is active, as evidenced by the presence of several young stellar objects and HH objects; these phenomena mainly concern stars of small and medium mass

Due to its brightness and extent, it is one of the most photographed objects in the Northern Celestial Hemisphere.The Pelican Nebula (also known as IC 5067/70) is an H II region in the constellation Cygno, near Deneb (the swan's tail and its brightest star); it belongs to the same giant molecular cloud as the nearby North American Nebula and is easily photographed. Its distance is estimated at around 600±50 parsecs (1956±163 light years).

Within it are active phenomena of star formation, as evidenced especially by the presence of HH objects; these phenomena mainly concern stars of small and medium mass.

Thor's Helmet is about 30 light-years across. In fact, the helmet is more like an interstellar bubble, blown as a fast wind from the bright, massive star near the bubble's center inflates a region within the surrounding molecular cloud. Known as a Wolf-Rayet star, the central star is an extremely hot giant thought to be in a brief, pre-supernova stage of evolution. NGC 2359 is located about 15,000 light-years away in the constellation Canis Major.(science.nasa.gov/ngc-2359-thors-helmet)

Description:

Nestled amidst the celestial splendor of Orion, M78 emerges as a mesmerizing portrait of interstellar artistry. This iconic reflection nebula, located about 1,350 light-years away, owes its ethereal glow to the light of young, massive stars scattering off the surrounding cosmic dust. Captured with a precision 9.25-inch Schmidt-Cassegrain telescope at a focal length of 1635mm, this image delves into the heart of one of the Orion molecular cloud complex's brightest treasures. Dark tendrils of dust weave through the nebula like veins, while the faint blue haze hints at the energetic processes shaping this stellar nursery. In the proximity of neighboring giant nebulae like the Orion Nebula (M42) and Barnard's Loop, M78 feels like a hidden jewel in the vast tapestry of cosmic creation. This detailed view not only highlights its scientific importance as a site of active star formation but also invites the viewer to imagine the dynamic forces at work in this bustling galactic neighborhood.

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.

2h 20min integration with Optolong 3nm filters, Sharpstar 61EDPH on iOptron GEM28 and ASI1600MM Pro. Recorded with ASI AIR Plus.

Another view of Venus from the 12.05.18 this time with IR and UV filters.

The resultant colour image was generated by mapping the Baader 685nm IR filter to red, the UV filter to blue and a synthetic green (an average of R & B) being mapped to the green channel.

Imaged with a Celestron C8 a ZWO290MM camera and Optolong UV and Baader IR filters.

Ahora si como la queria!

La paleta HOO tiene el sesgo de que no tiene señal Verde en canal Verde sino que en el canal verde se duplica el Oiii, por consiguiente toda la foto es Bicolor, sin

En este caso tome el verdadero canal Verde y arme una paleta Ha G Oiii

Y finalmente las estrellas tienen su color amarillo y azul propio de su temperatura.

Los colores obtenidos son reales..... aqui nobhay falso color!

Aun quiero probar de incorporarle una Lum sintetica producto de la suma del Ha y el Oiii, a la vez tengo completo los canales RGB asi que aun queda tela.....
