No suelo reprocesar fotografÃas del baúl, pero con esta llevaba mucho tiempo con ganas de empezar la edición desde cero. Nunca se me olvidará el buen rato que pasamos cuando nos dejaron entrar de noche, corrÃa el mes de junio de 2016, y recuerdo como intentábamos iluminar torpemente el frente escénico con nuestras linternas a la vez que formábamos la panorámica. No hemos vuelto a conseguir que nos dejaran entrar de noche, ya que tuvimos muy poco tiempo para realizar la toma, me hubiera gustado pasar una noche completa ahà para intentar la marabunta de ideas que llevaba planificadas... eran otros tiempos.
Se aprecia mucho mejor a pantalla completa, si puede ser en un ordenador. La configuración para la panorámica la realizamos a ISO 800, f/3.5 y 30 segundos de exposición, con 7 tomas verticales; en cada una de las tomas se iluminó el frontal desde ambos laterales con dos linternas de luz cálida y parte de la iluminación del frente escénico procedÃa de la propia luz de la ciudad.

Ya en estas fechas comenzamos a dejar el verano atrás y damos la bienvenida al otoño. Recordamos los primeros dÃas de verano de este año 2020, cuando los cazadores de estrellas se encuentran a máximo rendimiento y las noches se impregnan de magia. Nos encontramos en el Parque Natural de Cornalvo, al inicio del camino que conduce al Rugidero, creo que este es el lugar que más veces hemos fotografiado.
De las escasas tomas con la VÃa Láctea este año, panorámica realizada a partir de 7 tomas verticales, de 15 segundos cada una, a f/2.0 e ISO 2500. En esta ocasión conté con un iluminador especial, Alberto se encargó de darle luz a cada exposición con una linterna cálida de forma homogénea, para que no se notara al formar la panorámica; pronto me quita la cámara...

Already at this time we begin to leave the summer behind and we welcome the fall. We remember the first days of summer of this year 2020, when the star hunters are at their best and the nights are impregnated with magic. We are in the Cornalvo Natural Park, at the beginning of the path that leads to Rugidero, I think this is the place that we have photographed the most times.
Of the few shots with the Milky Way this year, a panorama made from 7 vertical shots, of 15 seconds each, at f/2.0 and 2500 ISO. At this time I had a special illuminator, Alberto was in charge of lighting each exposure with a torch with warm light in a homogeneous way, so that it is not noticeable when forming the panorama; soon he'll take my camera away ...

Il ponte Pietra è un ponte di Verona sul fiume Adige, l'unico rimasto di epoca romana. Il ponte si colloca in un punto che fin dalla Preistoria doveva presentare un guado, punto d'incontro cruciale tra diverse vie di comunicazione a cui si deve la nascita della città di Verona.
The Pietra bridge is a bridge of Verona on the Adige river, the only one left from the Roman era. The bridge is located in a point that since prehistoric times had to present a ford, a crucial meeting point between different ways of communication to which we owe the birth of the city of Verona.
CTB 1 is a supernova remnant (SNR) in the constellation Cassiopeia and a source of optical, radio, and X-ray emissions. A recent study reports that a pulsar was born from the supernova that produced CTB 1 and ejected into the galaxy.
CTB 1 is approximately 9784 light years away and physically spans another 98 light years in diameter while it is dated to be approximately 10,000 years old.

Subimos a lo más alto de la Sierra del Centinela, donde aparte de las espectaculares vistas, nos encontramos con la Ermita de la Virgen de Fátima. Con una llamativa forma circular, de color blanca, fue construida a mediados del siglo XX con la ayuda de todo el pueblo de Alcuéscar y se la conoce como la primera ermita dedicada a la advocación de Fátima en España.
Un curioso invitado se nos coló en la toma, si observáis con detenimiento podéis encontrarlo coronando la ermita. Con alguna dificultad para encuadrar, nos decantamos por realizar una panorámica a partir de tres tomas verticales, de 15 segundos cada una, a f/1.8 e ISO 2500.

We climb to the top of the Sierra del Centinela, where apart from the spectacular views, we find the Hermitage of the Virgin of Fátima. With a striking white circular shape, it was built in the mid-20th century with the help of the entire town of Alcuéscar and is known as the first hermitage dedicated to the invocation of Fatima in Spain.
A curious guest slipped into the shot, if you look closely you can find him crowning the hermitage. With some difficulty in framing, we opted for taking a panorama from three vertical shots, of 15 seconds each, at f / 1.8 and ISO 2500.
The Crab Nebula AKA, M1 (Messier 1), NGC 1952, Taurus A is a supernova remnant and pulsar wind nebula in the constellation of Taurus.. It is about 6,500 light-years from earth and contains a pulsar neutron star, which would explain the brightness of the cloud. I took this image using narrowband filters over many nights for more than 11 hours of exposure time.
Sh2-155 was first noted as a galactic emission nebula in 1959 in the extended second edition of the Sharpless catalogue.
The name "Cave Nebula" was coined for this object by Patrick Moore, presumably derived from photographic images showing a curved arc of emission nebulosity corresponding to a cave mouth.
Sh2-155 is a diffuse nebula in the constellation Cepheus, approximately 2,400 light-years away from Earth.

Airglow phenomenon - 2023-06-23
Images captured during our Milky Way Workshop from Writing-on-Stone Provincial Park.
Airglow (also called nightglow) is a faint emission of light by a planetary atmosphere. Airglow is caused by various processes in the upper atmosphere of Earth such as, luminescence caused by cosmic rays striking the upper atmosphere, and chemiluminescence caused mainly by oxygen and nitrogen reacting with hydroxyl free radicals at heights of a few hundred kilometres. It renders as blue or green wisps or rays on images.
This image is a stack of 9 * 20 seconds. The rays are less pronounced as the stacking process mutes them. The details in the milky way core are much clearer than the single exposure.

The Spaghetti Nebula is a supernova remnant (SNR) in the Milky Way, straddling the border between the constellations Auriga and Taurus. The nebulous area has an almost spherical shell and a filamentary structure. It is believed that the stellar explosion left behind a rapidly spinning neutron star known as a pulsar in the nebula core, emitting a strong radio signal. Sh2-240 is approximately 3,000 light-years from earth.

An open cluster discovered by Caroline Herschel in 1787. William Herschel included his sister's discovery in his catalog. This reasonably large nebula is located in Cepheus. It is extremely difficult to observe visually.
Located 7200 light years away, the Wizard nebula, surrounds developing open star cluster NGC 7380. Visually, the interplay of stars, gas, and dust has created a shape that appears to some like a fictional medieval sorcerer. (I personally don't see that)

eN_ the Milky Way is nothing more than one among billions of spiral galaxies that inhabit the universe. From our perspective on earth, we see it as a curved strip that crosses the sky from one side to the end of the celestial sphere, the bright whitish strip we call the Milky Way is nothing more than a part of it, its disc, which is where most of the stars, nebulas, dust and gas are concentrated in the galaxy, but there is also the halo and galactic bulge, the halo is all that star-filled sector where the sky is darker, where stars and globular clusters are found and The bulge is the nucleus of the Milky Way. In this capture, in addition to observing part of the disk (the entire bright strip), we also observe the galactic bulge, more than 26 thousand light years away, it is the brightest area of ​​stars in the image (right center) where Sagittarius A * lies, the supermassive black hole that dominates our galaxy, and finally you see part of the Halo, that sector where there are stars but the background is dark. With more than 100 thousand light years in diameter our galaxy is the second largest in the local group (after andromeda) and a clear example of a barred spiral.

La vÃa Láctea no es mas que una entre miles de millones de galaxias espirales que habitan el universo. Desde nuestra perspectiva en la tierra, la vemos como una franja curva qur atraviesa el cielo de un lado hasta completar la esfera celeste, la franja blanquecina brillante que llamamos Via Láctea no es mas que una parte de ella, su disco, que es donde se concentran la mayor parte de estrellas, nebulosas, polvo y gas en la galaxia, pero ademas existe el halo y bulbo galáctico, el halo es todo ese sector lleno de estrellas donde el cielo es mas oscuro, donde se encuentran estrellas y los cúmulos globulares y el bulbo es el nucelo de la vÃa Láctea. En esta captura ademas de observar parte del disco (toda la franja brillante) también observamos hacia el bulbo galactico, a mas de 26 mil años luz, es la zona mas brillante de estrellas en la imagen (centro derecha) donde yace Sagitario A*, el agujero negro supermasivo que domina nuestra galaxia, y por ultimo observas parte del Halo, ese sector donde hay estrellas pero el fondo es oscuro. Con mas de 100 mil años luz de diámetro nuestra galaxia es la segunda mas grande del grupo local (después de andromeda) y un claro ejemplo de espiral barrada.

We finally got a clear cloudless night. Too bad it coincides with one of the shortest nights of the year. During the weeks surrounding summer solstice, astronomical darkness does not occur in Northern latitudes. We instead get a few hours (~3.5 hours) of nautical twilight.
Nautical twilight occurs when the sun is between 6 degrees and 12 degrees below the horizon. Astronomical twilight occurs when the sun is between 12 degrees and 18 degrees below the horizon. Night is classified when the sun is 18 degrees or farther below the horizon.

I am fascinated with faint supernova remnants. This one is particularity dim. It lies at the head of Cygnus the swan, on the border of Vulpecula. Located approximately 3,200 light years away.
Supernova remnants (SNR) are formed when a large star ends its life in a supernova explosion. About 300 of these remnants are currently known in our galaxy. One of the most famous remnants, the Veil Nebula, also located in the constellation of Cygnus. Although this is the most famous one in this constellation, it’s not the only SNR.
SNR G65.3+5.7 was discovered by Gull et al. (1977) during an OIII survey of the Milky Way. Some parts of this SNR were already catalogued by Stewart Sharpless in his SH2 catalog as SH2-91, SH2-94 and SH2-96, but they were not recognized as being part of a bigger structure at that time. The idea that they could be part of a larger SNR was postulated by Sidney van den Bergh in 1960, but it took until 1977 for this to be confirmed.
