M24 chiamata anche Nube delle Caustiche , è un vasto insieme di stelle visibile nella costellazione del Sagittario. M24 comprende anche gli ammassi IC 4715 e NGC 6603.

M24 si individua circa 2° a nord dalla stella μ Sagittari e giace in un campo di stelle molto ricco a causa della presenza di grandi nubi stellari della Via Lattea; si mostra ad una semplice osservazione come una macchia chiara più brillante rispetto allo sfondo della Via Lattea, già molto luminosa in direzione del Sagittario per la presenza del centro galattico. Un semplice binocolo consente invece di rivelare centinaia di astri minuti, tutti concentrati in uno spazio di poco più di un grado quadrato. Un telescopio amatoriale consente di individuare migliaia di stelle, spesso di colori contrastanti; si può inoltre notare come i confini occidentali siano più netti di quelli orientali, effetto causato dalla presenza di una nebulosa oscura presso i suoi bordi.

M24 può essere osservata con discreta facilità da gran parte delle aree popolate della Terra, grazie al fatto che è situata a una declinazione non eccessivamente australe: in alcune aree del Nord Europa e del Canada, nei pressi del circolo polare artico, la sua visibilità è comunque molto difficile, mentre nell'Europa centrale appare relativamente bassa; dall'emisfero sud la nebulosa è ben visibile alta nelle notti dell'inverno australe e nella sua fascia tropicale può vedersi perfettamente allo zenit.

Il periodo migliore per la sua osservazione nel cielo serale è quello compreso fra giugno e ottobre.

From Wikipedia: The Triangulum Galaxy is a spiral galaxy approximately 3 million light-years from Earth in the constellation Triangulum. It is cataloged as Messier 33 or NGC 598. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, which includes the Milky Way, the Andromeda Galaxy and about 44 other smaller galaxies. It is one of the most distant permanent objects that can be viewed with the naked eye.

Crop of the Cygnus wall

 

The North America Nebula covers a region more than ten times the area of the full moon, but its surface brightness is low, so normally it cannot be seen with the unaided eye. Binoculars and telescopes with large fields of view (approximately 3°) will show it as a foggy patch of light under sufficiently dark skies. However, using a UHC filter, which filters out some unwanted wavelengths of light, it can be seen without magnification under dark skies. Its shape and reddish color (from the hydrogen Hα emission line) show up only in photographs of the area.

 

The portion of the nebula resembling Mexico and Central America is known as the Cygnus Wall. This region exhibits the most concentrated star formation.

 

At optical wavelengths, the North America Nebula and the Pelican Nebula (IC 5070) appear distinct as they are separated by the silhouette of the dark band of interstellar dust L935. The dark cloud is however transparent to radio waves and infrared radiation, and these wavelengths reveal the central regions of Sh2-117 that are not visible to an ordinary telescope, including many highly luminous stars.

 

The distances to the North America and Pelican nebulae were controversial, because there are few precise methods for determining how far away an HII region lies. Until 2020, most astronomers accepted a value of 2,000 light years, though estimates ranged from 1,500 to 3,000 light years.

I found a really weird weather that allowed me to take 3 completely different picture in less than 24 hours.

After the sunset, the sky was completely full of clouds, but fortunately they opened exactly when Milky Way was aligned with Tre Cime!

The Dumbbell Nebula - Messier 27 - is a planetary nebula located in constellation Vulpecula (“little fox”) at about 1200 light years from Earth. The term planetary is somewhat misleading since it are not related to planets - the term derives from the fact that these nebulas are round when seen through a telescope. And in fact, M27 was the first planetary nebula to be spotted by Charles Messier.

In reality, these nebulas are the result of stars that shed their outer layers by the end of their life. And in this photo, that star can be seen right in the center of it. And like many of their kind, knots of dust do exist nearby the star, leading to a patterned look near the center.

Interestingly, the colors are associated with the chemical compounds that exist in this region - blue is oxygen and red hydrogen and these are the building blocks of water. No wonder that water is thought to be a common compound in the Universe.

Testing with the new Optolong L-synergy filter

a 7nm dual-band S2 O3 filter

which allows you to combine shots with the classic HA O3 dual-band filters and create a composition in the Hubble Palette using an OSC color camera.

The Heart Nebula IC1805, taken with the L-synergy filter, was also truly impressed with the amount of O3 present and its clarity. The filter is free of halos and gradients, making post-processing very easy.

 

Thanks to Optolong Astronomy Filter for giving me the opportunity to test this filter.

After preprocessing in Nebulosity and initial registration and stacking in PixInsight, I combined the RGB channels first. This at least brought out some color before I started layering in the luminosity channel. Continued processing in PixInsight and final touches in Photoshop. I feel like I need to go back and add some H-alpha when I get a chance.

See if you can find the face in the shot. This is only seen in the Southern hemisphere never see in

northern skies. For this shot I did not take RGB stars.

The first image of 2023, and because Orion is already setting relatively early, it made sense to revisit M42, The Orion Nebula. This shot is a composite image made from three different exposures and stacked separately. The lower exposure images were then blended with the higher exposure image to reduce the overexposed regions to just The Trapezium Cluster (the asterism of six very bright, young stars in the central region).

 

[Summarised From Wikipedia] The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated approximately 1,344 light-years away in the constellation of Orion. It is one of the brightest nebulae and is visible to the naked eye in the night sky. M42 is the closest region of massive star formation to Earth and is estimated to be 24 light-years across.

 

The Orion Nebula is visible with the naked eye and is seen as the middle "star" in the "sword" of Orion, which are the three stars located south of Orion's Belt. The "star" appears fuzzy to sharp-eyed observers, and the nebulosity is obvious through binoculars or a small telescope.

 

Just as The Trapezium Cluster is a component of the much larger Orion Nebula, so the Orion Nebula is in turn surrounded by the much larger Orion molecular cloud complex which is hundreds of light years across, spanning the whole Orion Constellation.

He vuelto a las tomas de 10 min en banda estrecha, el rendimiento es fenomenar....

La zona de Sadr en el cisne es un area rica en emisiones de Hidrogeno, contrastada con nubes de polvo de absocion que tapan la Nebulosa, misma que asemeja a las alas de una Mariposa.

L'amas de la Chouette ou « E.T. Cluster » (NGC 457 ou Caldwell 13), est un très jeune amas ouvert situé dans la constellation septentrionale de Cassiopée. Cet amas d'étoiles a été découvert par William Herschel en 1787. Il renferme quelque quatre-vingts étoiles et sa distance au Soleil est estimée à ∼7 920 années-lumière. Les dernières estimations donnent un âge de 21 millions d'années à cet amas. Sa taille apparente est de 20,0 minutes d'arc, ce qui, compte tenu de la distance, donne une taille réelle maximale d'environ 46 années-lumière.

 

Aussi dans l'image l'Amas NGC436.

 

NGC 457 (also designated Caldwell 13, and known as the Dragonfly Cluster, E.T. Cluster, Owl Cluster, Kachina Doll Cluster or Phi Cassiopeiae Cluster is an open star cluster in the constellation Cassiopeia.

تصويري للمذنب الاخضر الذي يزور الارض هذة الايام علما ان اخر زيارة له كانت قبل ٥٠،٠٠٠ الف سنة وكانت في العصر الحجري. بالرغم من انني لم استطع مشاهدتة بالعين المجردة و لكن تمكنت من مشاهدتة بمساعدة المنظار وتصويرة باستخدام التلسكوب، حيث تمكنت من الحصول على ساعة و ٢٠ دقيقة من التصوير. This is my image of the Green comet C/2022 E3 ZTF on 28 Jan 2023. This comet is last seen before 50,000 years in the stone age. I could not see it by the naked eyes but I did see it by binocular. It appears as a hazy white patch. I managed to get 1 hour & 20 minutes as 27 subs of 180 sec, 20 Flats, 20 Darks, 50 Bias. Gear setup: WO Zenithstar 73 @ f/5.9, iOptron GEM 45, guided by ZWO Mini guide scope & ZWO 120, ZWO 2600MC @ -10, Optolong L-Pro. Guided by PHD2, Captured by APT, stacked and processed by PI.

NGC 2264 Christmas Tree Cluster/Cone Nebula

 

NGC 2264 is the designation number of the New General Catalogue that identifies two astronomical objects as a single object: the Cone Nebula, and the Christmas Tree Cluster. Two other objects are within this designation but not officially included, the Snowflake Cluster, and the Fox Fur Nebula.

 

All of the objects are located in the Monoceros constellation and are located about 800 parsecs or 2,600 light-years from Earth. NGC 2264 is sometimes referred to as the Christmas Tree Cluster and the Cone Nebula. However, the designation of NGC 2264 in the New General Catalogue refers to both objects and not the cluster alone. (Wikipedia.org)
