Dalla città, con il 72ED e il filtro SV240, la Iris Nebula (NGC 7023) rivela le sue sfumature più delicate: un cuore azzurro immerso in un mare di polveri interstellari.
Situata nella costellazione di Cefeo, a circa 1.300 anni luce di distanza, è una nebulosa a riflessione illuminata dalla giovane stella SAO 19158, di tipo spettrale B2V.
Le sue nubi di gas e polveri diffondono la luce blu della stella centrale, mentre le regioni più scure circostanti assorbono la luce delle stelle di fondo, delineando intricate trame di materia cosmica.
L’intero campo è un mosaico di nebulosità diffuse e regioni di polvere fredda, dove nascono nuove stelle.
Riuscire a catturare tanto dettaglio da un cielo cittadino è una piccola vittoria contro l’inquinamento luminoso.
Un fiore di luce sospeso nel buio, che continua a ricordarci quanto l’universo sia vivo anche dove sembra silenzioso.

Questa è una bellissima zona della Via lattea nella costellazione di Cassiopea ai confini con quella del Cefeo. L'immagine ritrae la famosa "Nebulosa Bolla", indicata con le sigle "NGC7635", C11, LBN548, Sh2-162. Nei suoi dintorni insieme al noto ammasso aperto "M52 (NGC7654)", con il suo vicino prospettico MWSC 3726 (da the Milky Way Star Cluster catalog), spiccano altre nebulose ad emissione Ha, come "NGC7538", Sh2-159, Sh2-161, e nebulose oscure come LDN1231, LDN1232, LDN1225.(vedi note sull'immagine)
Probabilmente il 5h e 45 min di integrazione in banda stretta non sono tante (meglio sarebbe stato integrare 12-15h), ma in questo periodo dell'anno ci vorrebbero anche mesi.
Ciò malgrado, il rapporto focale f/4 mi ha dato la possibilità di estrapolare dicreto segnale debole senza portarmi dietro troppo rumore.

This is a beautiful area of the Milky Way in the constellation of Cassiopeia on the border with Cepheus. The image depicts the famous "Bubble Nebula", indicated with the acronyms "NGC7635", C11, LBN548, Sh2-162. In its surroundings together with the well-known open cluster "M52 (NGC7654)", with its prospective neighbor MWSC 3726 (from the Milky Way Star Cluster catalog), other Ha emission nebulae stand out, such as "NGC7538", Sh2-159, Sh2-161, and dark nebulae such as LDN1231, LDN1232, LDN1225. (see notes on the image)
Probably the 5h and 45 min of narrow band integration is not much (it would have been better to integrate 12-15h), but in this period of the year (winter) it would take even months.
Nevertheless, the f/4 focal ratio gave me the ability to extract a decent amount of weak signal without carrying too much noise.

NGC7023 – Iris Nebula 1,300 light-years away, in the constellation Cepheus. Within the Iris itself, dusty nebular material surrounds a hot, young star. The dominant color of the brighter reflection nebula is blue, characteristic of dust grains reflecting starlight. Central filaments of the reflection nebula glow with a faint reddish photoluminesence as some dust grains effectively convert the star's invisible ultraviolet radiation to visible red light. Infrared observations indicate that this nebula contains complex carbon molecules known as PAHs. The pretty blue petals of the Iris Nebula span about six light-years. The colorful field-of-view stretches almost five Full Moons across the sky.

NGC7023 - Nebulosa Iris a 1.300 años-luz de distancia, en la constelación de Cefeo. Dentro de la propia Iris, el material nebular polvoriento rodea a una estrella joven y caliente. El color dominante de la nebulosa de reflexión más brillante es el azul, característico de los granos de polvo que reflejan la luz estelar. Los filamentos centrales de la nebulosa de reflexión brillan con una tenue fotoluminiscencia rojiza, ya que algunos granos de polvo convierten eficazmente la radiación ultravioleta invisible de la estrella en luz roja visible. Las observaciones en infrarrojo indican que esta nebulosa contiene moléculas complejas de carbono conocidas como HAP. Los bonitos pétalos azules de la nebulosa del Iris abarcan unos seis años-luz. El colorido campo de visión se extiende casi cinco Lunas Llenas a través del cielo.

La nebulosa 7822 es un complejo de formación de estrellas donde se encuentra el cúmulo globular conformado por Berkeley 59, a una distancia de 1 Kpc (unos 3300 años luz), siendo un sistema binario con su estrella principal (DB+66 1673) del tipo OSV. Ella es la fuente primaria que ilumina la nebulosa y forma los pilares de creación (como M16), zona de creación estelar. Esta estrella es una de las más caliente y brillantes de las cercanas al sol con una temperatura cercana a 45000 K y unas 100.000 veces más brillante que el Sol.
El cúmulo NGC 7762 se encuentra en la zona inferior izquierda.
La estrella destacada cercana al cúmulo, se trata de una estrella variable bien conocida y el fondo es el resultado del remanente de una supernova.

Nebula 7822 is a star formation complex where the globular cluster formed by Berkeley 59 is found, at a distance of 1 Kpc (about 3300 light years), being a binary system with its main star (DB + 66 1673) of the type OSV. She is the primary source that illuminates the nebula and forms the pillars of creation (like M16), the zone of stellar creation. This star is one of the hottest and brightest of those close to the sun with a temperature close to 45,000 K and about 100,000 times brighter than the Sun.
The cluster NGC 7762 is in the lower left area.
The prominent star near the cluster is a well-known variable star, and the background is the result of a supernova remnant.
Un piccolo telescopio, una lunga attesa e un frammento remoto della Via Lattea. Ancora una volta, il cielo unisce potenza e fragilità, mistero e luce.
Nel cuore della costellazione di Cefeo, la Cave Nebula (Sh2-155) si mostra in tutta la sua eleganza: un complesso intreccio di nebulosità a emissione, riflessione e assorbimento. A circa 2.400 anni luce da noi, questa regione è un laboratorio di formazione stellare, dove venti energetici e radiazioni ultraviolette scolpiscono le nubi di gas, mentre le polveri creano la celebre cavità scura che ricorda l’ingresso di una grotta cosmica.
In questa immagine, catturata con un rifrattore da 72 mm e il filtro SV220, le sfumature più delicate emergono con sorprendente grazia: il rosso dell’idrogeno, tenuemente modulato, si fonde con i toni più freddi delle polveri illuminate.
Due ore di esposizione dalla città, con la camera ASI 533 MC Pro, integrate con cura per mostrare la complessità del campo senza tradire la finezza dei dettagli.

LDN 1251 è una nebulosa oscura situata a circa 1.000 anni luce dalla Terra, soprannominata Nebulosa Pesce Marcio. La forma allungata di LDN 1251 è probabilmente legata all'interazione con una supernova vicina. Al suo interno è visibile una galassia a spirale distante chiamata PGC69472. La coda della nebulosa oscura prende un nome diverso perché è catalogata come un oggetto separato, denominato LDN 1247.
Vdb 152 è caratterizzata dalla nebulosa oscura Barnard 175, o LDN 1217. La nebulosa è debolmente illuminata dalla luce ultravioletta, che produce un bagliore rossastro caratteristico delle nebulose a emissione rossa estesa. All'interno della nebulosa si trova una stella di sequenza principale bianco-blu, BD+69 1231, la cui radiazione conferisce una tonalità bluastra al gas circostante. La distanza della struttura dalla Terra è stimata in circa 1.300 anni luce.
La particolarità del complesso nebulare di polvere oscura catturato nell'immagine è che racchiude un'area in cui la formazione stellare è dominante, grazie al processo di intrappolamento dell'energia che consente di raggiungere le condizioni di temperatura e pressione necessarie per la fusione nucleare.

La nebulosa Iride, catalogata anche come NGC 7023, è una nebulosa a riflessione visibile nella costellazione di Cefeo: la stella che la illumina, e che ci permette di vederla, è una stella di settima magnitudine avvolta nella nebulosità assieme ad altre stelle meno luminose nate dalla condensazione di gas e polveri.
La distanza del complesso nebulare è di circa 1400 anni luce.
(info da Wikipedia)
Tutto il campo attorno alla nebulosa è ricco di polvere interstellare, ben visibile nell'immagine sotto forma di "nubi" marroncine.
----------
NGC 7023, also known as the Iris Nebula, is a reflection nebula in the constellation of Cepheus.

Campo de las nebulosas de la Burbuja , de la Garra de Langosta , del Mago y de la Caverna, mas el cúmulo M52
Campo en el que aparecen a parte de la nebulosas indicadas otras de interés entre objetos NGC, SH2 e IC, ver en la foto etiquetada también subida a Flickr.
Es un campo lleno de nubes de hidrogeno alfa , un campo difícil dada la magnitud débil de alguna de sus nebulosas, para sacarlas en todo su esplendor se necesitan algo mas de las casi seis horas que tiene la imagen, tomada desde Cabañeros (bortle 3).
Estas nebulosas se encuentran entre la costelación de Cefeo , Casiopea y Lacerta.
La imagen esta compuesta de 65 fotos tomadas con el telescopio WO 91 fluorestar con filtro L-enhance y cámara canon 6d modificada de rango completo. Procesada con Pixinsight, RC astro utilidades y PS.

Active nebula with Ha emissions, Herbi-Haro objects, young stars and blue reflections. About 3,000 light years away, towards the royal constellation of Cepheus. It contains clouds of bluish dust that reflect the youthful light of the stars. The paler, more extended filaments of reddish emission that blend with the bluish clouds are caused by dust grains that effectively convert invisible ultraviolet light from stars into visible red light.

Cassiopeia is part of the northen hemisphere, for me it forms an E or M. smile emoticon
The constellation is named after Cassiopeia, the queen of Aethiopia. Cassiopeia was the wife of Cepheus, King of Aethiopia and mother of Princess Andromeda. Cepheus and Cassiopeia were placed next to each other among the stars, along with Andromeda. She was placed in the sky as a punishment for her boast that her daughter Andromeda was more beautiful than the Nereids or, alternatively, that she herself was more beautiful than the sea nymphs. As punishment, she was forced to wheel around the North Celestial Pole on her throne, spending half of her time clinging to it so she does not fall off, and Poseidon decreed that Andromeda should be bound to a rock as prey for the monster Cetus, who was ravishing the Ethiopian coast. Andromeda was then rescued by the hero Perseus, whom she later married.

*************************************************
Casiopea, una joya llamativa del hemisferio norte, su forma de E o M, una de mis favoritas smile emoticon
Según la mitologia Casiopea es la madre de Andrómeda y esposa de Cefeo. Casiopea decía que Andromeda era mas bella que las hijas del dios del Mar Nereo, las Nereidas. Esto lo tomaron personal y le pidieron a Poseidón que se vengara, el tipo no dudo y mando al monstruo marino Cetus a las costas del país causando males considerables.
El oráculo de Amón aconsejó a Cefeo sacrificar a Andrómeda atándola a una roca para que el monstruo marino la matara. Perseo, venia de regreso de matar a la Medusa, vio a Andrómeda y se enamoró de ella. Le pidió al rey que la liberara, a cambio de que se le concediera su mano; Perseo mata al monstruo y posteriormente salva a Andrómeda.
Osea todo por Casiopea grin emoticon

El Planetario de Madrid quiere ofrecer a todos la posibilidad de acercarnos a las principales estrellas y constelaciones que se pueden contemplar en otoño. Con esta intención se propone un programa en directo: "El Cielo de una noche de otoño".
En el cielo de otoño aún podemos ver, nada más ponerse el Sol, un gran triángulo formado por las estrellas: Vega, Deneb y Altair. Las constelaciones más representativas del otoño son: Pegaso, Andrómeda, Perseo, Casiopea, Cefeo y Cetus. Estas constelaciones, como la mayoría, deben su nombre a los griegos, que las relacionaron con sus mitos y leyendas.
Podemos, cómo no, dejarnos maravillar por la Vía Láctea ó Camino de Santiago: es la galaxia a la que pertenecemos (junto a unos 200.000 millones de estrellas más), y que al estar imbuidos en ella percibimos como una gran mancha borrosa que cruza el cielo de lado a lado.
Además tenemos la posibilidad de contemplar otra galaxia a simple vista y el otoño es la mejor época del año; entre las estrellas de la constelación de Andrómeda, pero mucho más lejana que cualquiera de ellas, se puede localizar una débil nebulosidad: la galaxia Andrómeda que es el objeto más lejano que podemos observar sin ayuda de instrumental óptico.....

Philippe François Marie Leclerc de Hauteclocque, (22 November 1902 – 28 November 1947), was a French general during the Second World War. He became Marshal of France posthumously in 1952, and is known in France simply as le maréchal Leclerc or just Leclerc.

The son of an aristocratic family, de Hauteclocque graduated from the École spéciale militaire de Saint-Cyr, the French military academy, in 1924. After service with the French Occupation of the Ruhr and in Morocco, he returned to Saint-Cyr as an instructor. He was awarded the croix de guerre des théâtres d'opérations extérieures for leading goumiers in an attack on caves and ravines on Bou Amdoun on 11 August 1933. During the Second World War he fought in the Battle of France. He then became one of the first to make his way to Britain to fight with the Free French under General Charles de Gaulle, adopting the nom de guerre of Leclerc so that his wife and children would not be put at risk if his name appeared in the papers. He was sent to French Equatorial Africa, where he rallied local leaders to the Free French cause, and led a force against Gabon, whose leaders supported Vichy France. From Chad he led raids into Italian-controlled Libya. After his forces captured Kufra, he had his men swear an oath known today as the Serment de Koufra, in which they pledged to fight on until their flag flew over the Strasbourg Cathedral.
The forces under his command, known as L Force, campaigned in Libya in 1943, covered the Eighth Army's inland flank during its advance into Tunisia, and participated in the attack on the Mareth Line. L Force was then transformed into the 2e Division Blindée, although it was often referred to as La Division Leclerc. It fought under Leclerc's command in the Battle of Normandy, and participated in the liberation of Paris and Strasbourg. After the end of World War II in Europe in May 1945, he was given command of the French Far East Expeditionary Corps (Corps expéditionnaire français en Extrême-Orient, CEFEO). He represented France at the surrender of the Japanese Empire in Tokyo Bay on 2 September 1945. He quickly perceived the necessity for a political solution to the nascent conflict in Indochina, but once again was ahead of his countrymen, and was recalled to France in 1946. He was killed in an air crash in Algeria in 1947.

The Capture of Kufra (Prise de Koufra, Italian: Cufra) was part of the Allied Western Desert Campaign during the Second World War. Kufra is a basin and oasis group in the Kufra District of south-eastern Cyrenaica in the Libyan Desert. In 1940, it was part of the colony of Italian Libya Libia Italiana, which was part of Africa Settentrionale Italiana (ASI), which was established in 1934. With some early assistance from the British Long Range Desert Group, Kufra was captured by Free French Forces when the Italian and Libyan garrison surrendered after a siege from 31 January to 1 March 1941.
NGC7023 – Iris Nebula 1,300 light-years away, in the constellation Cepheus. Within the Iris itself, dusty nebular material surrounds a hot, young star. The dominant color of the brighter reflection nebula is blue, characteristic of dust grains reflecting starlight. Central filaments of the reflection nebula glow with a faint reddish photoluminesence as some dust grains effectively convert the star's invisible ultraviolet radiation to visible red light. Infrared observations indicate that this nebula contains complex carbon molecules known as PAHs. The pretty blue petals of the Iris Nebula span about six light-years. The colorful field-of-view stretches almost five Full Moons across the sky.

NGC7023 - Nebulosa Iris a 1.300 años-luz de distancia, en la constelación de Cefeo. Dentro de la propia Iris, el material nebular polvoriento rodea a una estrella joven y caliente. El color dominante de la nebulosa de reflexión más brillante es el azul, característico de los granos de polvo que reflejan la luz estelar. Los filamentos centrales de la nebulosa de reflexión brillan con una tenue fotoluminiscencia rojiza, ya que algunos granos de polvo convierten eficazmente la radiación ultravioleta invisible de la estrella en luz roja visible. Las observaciones en infrarrojo indican que esta nebulosa contiene moléculas complejas de carbono conocidas como HAP. Los bonitos pétalos azules de la nebulosa del Iris abarcan unos seis años-luz. El colorido campo de visión se extiende casi cinco Lunas Llenas a través del cielo.

Isaac Newton formulated the law of universal gravitation.
Albert Einstein formulated General Relativity, which is a relativistic theory of gravitation.
The gravity is a natural phenomenon by which the objects with mass are attracted to each other, effect mainly observable in the interaction between the planets, galaxies and other objects of the universe. It is one of the four fundamental interactions that cause the acceleration experienced by a physical body in the vicinity of an astronomical object. It is also called gravitational interaction or gravitation.
If a body is located in the vicinity of a planet, an observer at a fixed distance from the planet will measure an acceleration of the body directed towards the central area of ??that planet, if such a body is not subject to the effect of other forces.
Gravity is one of the four fundamental interactions observed in nature. It originates the large-scale movements that are observed in the universe: the orbit of the Moon around the Earth, the orbits of the planets around the Sun, etc.
Wizard Nebula is only 8,000 light-years away and in the photograph shown above surrounding NGC 7380, forming an even open cluster. Visually, the interaction of stars, gas and dust generated a way that for some vaguely reminiscent of a wizard medieval.La Wizard Nebula can be seen with a small telescope pointing towards Cefeo. Although this nebula will only last a few million years, some of the stars forming within it will live much longer than our sun.

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. This 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 relatively older stars are present in a small, circular cavity in the head of the globule. Winds from these young stars may have emptied the cavity.
La nebulosa Proboside di Elefante è costituita da una concentrazione di gas e polveri interstellari all'interno di una regione di gas ionizzati molto più ampia (IC1396) localizzata nella costellazione di Cefeo a circa 2400 anni luce dalla Terra. Questa nebulosa è ritenuta essere un sito di formazione stellare, contenendo diverse stelle molto giovani (meno di 100.000 anni) che sono state scoperte tramite immagini all'infrarosso nel 2003. Due stelle relativamente più vecchie sono presenti nella piccola cavità circolare nella testa del globulo. I venti provenienti da queste stelle possono aver creato la cavità.
