Era giunto il momento di provare ad acquisire ed elaborare foto astronomiche solo in Banda Stretta (BS). E per chi non lo sapesse questa scelta è dettata dal fatto che nelle zone con Inquinamento Luminoso (IL), soprattutto ultimamente con l'illuminazione a Led, è praticamente quasi impossibile fare fotografia Deep-Sky. Quindi gli astrofili ripiegano utilizzando filtri per fotografare oggetti celesti che emettono su una gamma di lunghezze d'onda specifica (H-alfa, H-beta, OIII, SII) come le nebulose ad emissione. Negli ultimi anni sono stati sviluppati filtri dual, tri e quad-band sempre più selettivi.
Per contro però al sensore arriva poco segnale quindi spesso i tempi di posa si debbono alzare come pure il numero di pose.
Inoltre l'immagine risultante presenta un certo sbilanciamento dei colori soprattutto le stelle.
Non è facile trovare un buon compromesso.
Eppure sarà stata la "fortuna del principiante", questa prova mi ha soddisfatto per il risultato raggiunto. Forse la luminosità dell'oggetto fotografato ha contribuito.
Si tratta della bellissima nebulosa ad emissione IC5070, detta
"Pellicano", acquisita con filtro Optolong L-eNhance (tri-band: H-alfa, H-beta e OIII).
L'immagine combinata in modalità RGB presentava la nebulosa con una dominante uniformemente rosso-arancio, che soffocava l'eventuale presenza di OIII (tipicamente blu-grigio). Poi, informandomi con altri astrofili e viaggiando sul web ho provato con SIRIL l'estrapolazione dei canali Ha e OIII e successivamente ho ricomposto in modalità RGB rispettivamente i canali HOO. Così facendo sono riuscito ad evidenziare entrambi i gas tra i quali si intrappolano molte nebulose oscure spettacolari.
________________
The time had come to try to acquire and process astronomical photos only in Narrow Band (NB). And for those who do not know, this choice is dictated by the fact that in areas with Light Pollution (LP) especially lately with LED lighting it is practically almost impossible to do Deep-Sky photography. So amateur astronomers fall back on using filters to photograph celestial objects that emit on a specific range of wavelengths (H-alpha, H-beta, OIII, SII) such as emission nebulae. In recent years, increasingly selective dual, tri and quad-band filters have been developed.
On the other hand, however, little signal reaches the sensor so often the exposure times must be increased as well as the number of exposures.
Furthermore, the resulting image presents a certain imbalance of colors especially the stars.
It is not easy to find a good compromise.
Yet it must have been "beginner's luck", this test satisfied me for the result achieved. Perhaps the brightness of the photographed object contributed.
This is the beautiful emission nebula IC5070, called "Pelican",
acquired with an Optolong L-eNhance filter (tri-band: H-alpha, H-beta and OIII).
The image combined in RGB mode presented the nebula with a uniformly red-orange dominant, which suffocated the possible presence of OIII (typically blue-gray). Then, by informing myself with other amateur astronomers and by traveling on the web, I tried with SIRIL the extrapolation of the Ha and OIII channels and subsequently I recomposed in RGB mode the HOO channels respectively. By doing this I was able to highlight both gases between which many spectacular dark nebulae are trapped.

The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus hence its alternate name The Cygnus Loop.
Formation of the nebula was due to a large star 20 times the size of our sun exploding between 10 and 20 thousand years ago as it went Super Nova. The explosion would have been so bright it would have been brighter than Venus and possibly visible in the daytime. The current area of the Super Nova Remnant is almost 3 degrees in diameter which is 6 times that of the Moon.
Many astrophotographers focus on 3 areas known as the Eastern Veil Nebula, The Western Veil Nebula (or Witched Broom) and Pickering Triangle.
The full image is a mosaic of 4 panels taken over 12 nights and a combined imaging time of 39.5 hours. It is a huge image by my standards and can be viewed in full resolution on my Astrobin page by following the links below.

IC 59 and IC 63 are found in the constellation Cassiopeia very near the bright star Gamma Cassiopeia. This set of objects is also known as the Ghost of Cassiopeia. Gamma Cassiopeia also has the informal nickname of Navi. The “IC” designation comes from a group of objects discovered between 1888 and 1907, most made possible by photography, and known as the Index Catalogue.
These nebulae are a combination of emission and reflection, they are located about 610 light years from Earth and are about 10 light years across. Gamma Cassiopeia provides the radiation to light up this area of dust and gas, eventually dissipating in the area.

Look for it 27,000 light years away in the constellation of Hercules. Also known as NGC 6341 it is one of the oldest star clusters in the Milky Way and was first discovered by Johann Elert Bode in 1777.
With an estimated 300,000 stars 100 light years across it should be quite easy to find in a pair of 10x50 binoculars, the best month for observing it is July.

Sh2-188 is a planetary nebula in Cassiopeia. It does not have an official name but is often called the "Shrimp Nebula" or even the "Dolphin Nebula" due to its shape. The expanding gas from the planetary nebula is colliding with ambient gas in the interstellar medium. The nebula is nearly circular in shape but is much brighter to the southeast (lower right) because the central star is moving rapidly in that direction. Faint wisps of gas can also be seen in the opposite direction.

NGC 6888 , nota anche come Nebulosa Crescente o con la sigla C 27, è una nebulosa diffusa visibile nella parte meridionale della costellazione del Cigno.
Si individua 2,5 gradi a sud-ovest della stella γ Cygni, subito ad ovest di un ricchissimo campo stellare, in cui sono inclusi oggetti come M29 e IC 4996. Si tratta di una tipica bolla di vento stellare generata da una massiccia stella di Wolf-Rayet (la HD 192163), che si trova al suo interno; questa stella sarebbe anche la responsabile della nebulosa, che costituirebbe il materiale degli strati più esterni della stella espulsi. Questo vento è andato a collidere col materiale espulso dalla stella durante il raggiungimento dello stadio di gigante rossa, fra 250.000 e 400.000 anni fa, energizzandolo. Il risultato è un guscio gassoso e la presenza di due onde d'urto, che hanno poi interagito col denso mezzo interstellare circostante.
La nebulosa si estende nello spazio per una dimensione di circa 16 anni luce.

This is the faint emission nebula designated as IC 1396 in the constellation Cepheus. This region is energized by the bright, bluish central multiple star HD 206267. You can see the Elephant’s Trunk Nebula, IC 1396A, on the lower edge of this image. From NASA APOD, “Stars could still be forming inside the dark shapes by gravitational collapse. But as the denser clouds are eroded away by powerful stellar winds and radiation, any forming stars will ultimately be cutoff from the reservoir of star stuff.”

The Owl Nebula (also known as Messier 97, M97 or NGC 3587) is a planetary nebula located approximately 2,030 light years away in the constellation Ursa Major. It was discovered by French astronomer Pierre Méchain on 1781. When William Parsons, 3rd Earl of Rosse, observed the nebula in 1848, his hand-drawn illustration resembled an owl's head. It has been known as the Owl Nebula ever since. The nebula is approximately 8,000 years old, It was formed from the outflow of material from the stellar wind of the central star as it evolved along the asymptotic giant branch. The owl-like appearance of the nebula is the result of an inner shell that is not circularly symmetric, but instead forms a barrel-like structure aligned at an angle of 45° to the line of sight. The nebula holds about 0.13 solar masses of matter, including hydrogen, helium, nitrogen, oxygen, and sulfur; all with a density of less than 100 particles per cubic centimeter.
Sharpless 101 is an H II emission nebula located in the constellation of Cygnus. It is also referred to as The Tulip Nebula It lies 6,000 light years distant.
Imaged over 2 nights 24th and 30th November under very bright moonlight 96 and 92 % respectively. The overall conditions were fairly poor.

En realidad, el objeto NGC 7023 es un cúmulo estelar, un cúmulo abierto asociado a la nebulosa (se encuentra dentro de la nebulosa), la cual está catalogada como vdB 139 o también LBN 487, mientras que el cúmulo es el objeto Cr 429.
En medio de la nebulosa hay una masiva y joven estrella de magnitud 7, SAO 19158, que es la que ilumina esta nebulosa. La nebulosa Iris es una nebulosa de reflexión, esto es, una enorme nube de gas y polvo que brilla debido a la reflexión producida por la luz de una o más estrellas cercanas, en este caso por la estrella SAO 19158. La nebulosa Iris es, de hecho, la nebulosa de la cual se formó la estrella SAO 19158. Al ser una luz de reflexión, adquiere el color de la estrella que la ilumina, azul. De todas maneras, estas nebulosas azules lo son más que la estrella que las ilumina; ello es debido a la dispersión del azul sobre las partículas de polvo de la nebulosa (como ocurre con el cielo azul de la Tierra).
Esta nebulosa tiene unos 6 años luz de diámetro y en sus alrededores pueden apreciarse unas zonas oscuras, sin estrellas, debido a que se encuentra en toda una gran nebulosa oscura situada en Cefeo. Tiene una magnitud aparente de 6,8, un brillo superficial de 11,3 mag/min arco2 y un tamaño aparente de 10′ x 8′.
La nebulosa Iris se encuentra en el cielo en la constelación de Cefeo, cerca de su segunda estrella más brillante, Alfirk (β Cep), a unos 1300 años luz de distancia.

NGC 1491 (also designated SH2-206 and LBN 704) is a bright emission nebula and HII region, located on the edge of a vast cloud region of neutral gas, about 10,700 light-years away in the Perseus arm of our Milky Way Galaxy in the constellation Perseus.
The blue 11.22 magnitude star (BD +50 ° 886) is illuminating the nebula while its strong stellar wind is “blowing” a bubble in the gas that immediately surrounds it. The intense radiation from the star is also eroding the gas clouds surrounding it. (Ref: annesastronomynews.com/photo-gallery-ii/nebulae-clouds/ng...)

IC 10 is an irregular galaxy in the constellation Cassiopeia. It was discovered by Lewis Swift in 1887. Edwin Hubble suspected it might belong to the Local Group of galaxies, but its status remained uncertain for decades. Its membership in the group was finally confirmed in 1996 by direct measurements of its distance based on observations of Cepheids. Despite its closeness, the galaxy is rather difficult to study because it lies near the plane of the Milky Way and is therefore heavily obscured by interstellar matter. The apparent distance between IC 10 and the Andromeda Galaxy is about the same as the apparent distance between the Andromeda Galaxy and the Triangulum Galaxy, which suggests that IC 10 may belong to the M31 subgroup. IC 10 is the only known starburst galaxy in the Local Group of galaxies.

Messier 81, M81 for short, or as it is also called, Bode's Galaxy, is a bright, swirling spiral galaxy located in the constellation Ursa Major just up and to the right of the top of the dipper in the Big Dipper asterism. This image captured at Grand Mesa Observatory highlights the interesting and delicate structure of its spiral arms.
First discovered by Johann Elert Bode in 1774, M81's relative brightness (apparent magnitude 6.94) and closeness (11.8 million light-years distant) makes it one of the most studied and photographed galaxies in the night sky. It contains an active galactic nucleus powered by a supermassive black hole at its center and was host to one of the brightest supernovae of the 20th century, SN 1993J. Also in this image, the blue blob above M81 is a satellite galaxy gravitationally locked to M81 called Holmberg IX, which is thought to have formed within the last 200 million years, making it the youngest nearby galaxy.

Here is a quick view of the star Deneb in the constellation Cygnus
From Wikipedia - Deneb is a first-magnitude star in the constellation of Cygnus, the swan. Deneb is one of the vertices of the asterism known as the Summer Triangle and the "head" of the Northern Cross. It is the brightest star in Cygnus and the 19th brightest star in the night sky, with an average apparent magnitude of +1.25. A blue-white supergiant, Deneb rivals Rigel as the most luminous first-magnitude star. However, its distance, and hence luminosity, is poorly known; its luminosity is somewhere between 55,000 and 196,000 times that of the Sun. Its Bayer designation is α Cygni, which is abbreviated to Alpha Cyg or α Cyg.

NGC 7331 is an unbarred spiral galaxy about 40 million light-years away in the constellation Pegasus. It was discovered by William Herschel in 1784. NGC 7331 is the brightest member of the NGC 7331 Group of galaxies. The other members of the group are the lenticular or unbarred spirals NGC 7335 and 7336, the barred spiral galaxy NGC 7337 and the elliptical galaxy NGC 7340. These galaxies lie at distances of approximately 332, 365, 348 and 294 million light years, respectively. The galaxy is similar in size and structure to the Milky Way, and is often referred to as "the Milky Way's twin"

IC 1396 / Elephant's trunk nebula
Hi everyone, Here is my newest picture.
This is the first time i'm using a dedicated astronomy camera and i'm really impressed and proud of this first result.
IC1396, also known as the elephant's trunk nebula is a emission nebula located in the constellation Cepheus at +-3000Ly from earth. This field of view represent a small part of a much bigger complex
I have used the HOO bi-color map to make a better separation between hydrogen alpha ( red ) and oxygen III ( blue ) gas. Unlike my last HOO combination attemp, this one has a better color saturation and contain less noise.
Hope you like these improvements,
Clear skies.

My first record of the Helix Nebula (nicknamed "Eye of God" because of its resemblance to an eye). The stacked frames, captured in four nights, totaled 15 hours and 50 minutes of exposure.
"The Helix Nebula (also known as The Helix or NGC 7293) is a large planetary nebula located in the constellation Aquarius. This object is one of the closest to the Earth of all the bright planetary nebulae. The estimated distance is about 700 light-years. The Helix Nebula has sometimes been referred to as the 'Eye of God' in pop culture". Source: eso.org (adapted)

El resto de supernova de Vela, también llamado Vela XYZ, SNR G263.9-03.3 y AJG 8,1 es un resto de supernova situado en la constelación de Vela. Es uno de los restos de supernovas más estudiados y más cercanos a la Tierra. Aunque se superpone al resto de supernova Puppis A, este último está unas cuatro veces más lejos.
El resto de supernova de Vela está asociado al púlsar de Vela (PSR J0835-4510): la relación entre ambos objetos astronómicos, realizada por astrónomos de la Universidad de Sídney en 1968, fue la prueba directa de que las supernovas dan lugar a estrellas de neutrones. La rotación de este púlsar, cuya frecuencia es de aproximadamente 11,2 Hz, ha sido estudiada exhaustivamente desde su descubrimiento. Fue el primer púlsar en donde se detectó una «falla» o «defecto» en su rotación; cuando se detectó de nuevo, dos años y medio más tarde, quedó claro que dichas «fallas» eran grandes y frecuentes. En estos episodios, la frecuencia de rotación se incrementa en unos 20 μHz. (Wikipedia)
Sh2-114, the Flying Dragon Nebula, is a very faint wispy collection of hydrogen alpha in the Cygnus region of the sky. Not to much is known about this nebula as it has not been studied in detail and not a common target for astrophotography.
who knows how long the "Dragon" will be flying for as we have no known measurements of distance to this nebula. The illusiveness and little information on the target is what really got me to image it. I like the unknowns within this target.
It was very faint and took 21 hours of Ha data to bring out the structure to some detail, worth every minute for me! I really enjoyed processing this image and watching the Dragon slowly start to appear before my eyes!
