This shot is born from the collaboration with astrophilist friend Mirco Turra , who shot last year with his old Newton 254/1200 double narrow band signal (H-alpha and OIII), to which I added this year the Ionized Sulfur signal (SII) and the RGB stars. I’ve been waiting for a year to build this Hubble palette and we finally did it (I promised her 😅).

The subject of the photograph is the famous Bubble Nebula (classified as NGC 7635, Sharpless 162, or Caldwell 11) in the Cassiopea constellation towards the Cepheus border, discovered in 1787 by William Herschel.

RCW 85 in Centaurus

In my opininion an exeptionally beautiful object.

When I started I actually thought I´d do it in Narrowband, in the end I thought the RGB looks better so I added 2 hours of luminance last night.

I only used the starless Ha image as luminance on the rays extending from RCW85.

Cosmic dust clouds are draped across a rich field of stars in this broad telescopic panorama near the northern boundary of Corona Australis, the Southern Crown. Less than 500 light-years away the denser clouds effectively block light from more distant background stars in the Milky Way. The entire vista spans about 5 degrees or nearly 45 light-years. Toward the right lies a group of bluish reflection nebulae cataloged as NGC 6726, 6727, 6729 and IC 4812. The dust also obscures from view stars in the region still in the process of formation. Smaller yellowish nebula NGC 6729 surrounds young variable star R Coronae Australis.

Image Description and Details : First image using an ASI2600MC with a RASA8! This shows 15 hours on the Messier 16 Eagle Nebula region of the sky in true color, without the use of any filter. This region is most often captured in narrowband, but I like the true color feel for this particular part of the sky. You can see the wings of the eagle spanning in rich hydrogen alpha gas, and the bright stars lighting up the famous Pillars of Creation.

Image Description and Details : Dagub Cave

While Socotra is better known for its endemic species of trees and wildlife, there are many limestone caves which dot the island. The largest of these is the Al-Hoq Cave but it is the Dagub cave which offers the more interesting nightscape thanks to its view to the south.
Stalactites, formed over centuries of water dripping from the cliffs, come together at the mouth of the cave to form an interesting foreground against which to frame the night sky. Socotra is very sparsely populated and as a result the skies are very clear whenever the clouds part ways. Being close to the equator, allows one to frame objects otherwise seen only in the Southern Hemisphere. See in the sky here from left to right is the Coalsack Nebula, the Southern Cross, the Running Chicken Nebula, Eta Carina and Gum 15…..

Image Description: IC 4601 is a reflection nebula which is located about 420 light-years away in Scorpius.

The bluish reflection nebula with the two embedded double stars is IC 4601 (vdB 102,vdB 103), the yellowish reflection nebula is vdB 101. The two reflection nebulae appear so different due to the temperature differences of the illuminating stars.

These types of nebulae are called “reflection,” because they reflect the light of nearby stars.

IC 4601 is illuminated by the intense radiation of the stars present in its vicinity, among which the most brilliant star HD 147010, and the two stars of a binary system known as HD 147013, which are all blue giants.

The dust of IC 4601 contains the heavy elements that planets are made of and plays a major role in the creation of new stars. There probably are baby stars wrapped in these blankets of dust.

Image Description and Details : In order to image the Rho Ophiuchi cloud complex, we decided to create a two-panel mosaic, so as to have a good resolution and be able to walk around the image.

The Rho Ophiuchi cloud complex is a complex of interstellar clouds with mainly dark nebulae.

At a distance of around 450 light-years, it is one of the solar system's closest star nurseries.

Rho Ophiuchi is the star system in the blue area on the left of the image. With a surface temperature of over 6,500K (making them more than 160 times brighter than the Sun), these stars reflect their light onto the dark clouds around them.

Some structures appear to be the result of a shockwave passing through the cloud from the direction of the nearby Scorpius-Centaurus association.

Dust and gas that makes the star system appear 1.45 magnitudes dimmer than it really is. Without the interstellar extinction, Rho Ophiuchi would shine at magnitude 3.18.

We can also find two globular clusters: M4 (the largest) and NGC 6144 (the smallest).

This area of the sky is known for its wide range of colors, making it a very photogenic zone.

Image Description and Details : 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 2400 light years away from Earth. The piece of the nebula shown here is the dark dense globule IC 1396A; it is commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright massive star (HD 206267) that is just to the east of IC 1396A.
The Elephant's Trunk Nebula is now thought to be a site of star formation, containing several very young (less than 100000 years) stars that were discovered in infrared images in 2003. Two 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.
The combined action of the light from the massive star ionizing and compressing the rim of the cloud, and the wind from the young stars shifting gas from the center outward lead to very high compression in the Elephant's Trunk Nebula. This pressure has triggered the current generation of protostars.

Image Description and Details : The Black Eye Galaxy, or M64, is located 17 million light-years away in the constellation Coma Berenices. Its nucleus is packed with impressive dust lanes laden with rigorous star formation.
