IMAGE DESCRIPTION AND DETAILS :

NGC 7129 is a celestial object visible during summer nights in the northern hemisphere (circumpolar visible) in the central-western part of the Cepheus constellation, approximately 4 degrees away from the brightest star of the constellation, Alderamin (magnitude 2.4), in the northeast direction.
NGC 7129 is a reflection nebula located about 3,100 light-years away from Earth. Unlike emission nebulae that emit their own light due to ionization of gas, reflection nebulae do not emit light themselves. Instead, they shine by reflecting the light of nearby stars, typically young and hot stars, that are embedded within or close to the nebula. The light from these stars gets scattered and diffused by dust and gas particles in the nebula, creating a beautiful glow and giving the nebula its characteristic blue color.
NGC 7129 is associated with a young open star cluster, containing young, hot, and massive stars that formed relatively recently from the same molecular cloud of gas and dust.
Reflection nebulae like NGC 7129 typically show characteristic emission spectra with prominent spectral lines of ionized hydrogen (H-alpha) and other elements. The H-alpha line is often observed in red light due to the ionized hydrogen gas.
The dust grains within the reflection nebula can cause interstellar extinction, meaning they absorb and scatter light from background stars, making them appear fainter and redder.
NGC 7129 represents the remnants of a just hatched cocoon of O and B spectral class stars, making it a nursery of sorts. The recently born, young, and powerful stars, estimated to be a few hundred thousand years old, particularly the O-class stars, are among the hottest and most luminous in the universe. Their surface temperatures are significantly higher, exceeding 30,000 degrees Celsius, approximately six times hotter than our star (which shines with yellow light at about 5,600 degrees Celsius). This high temperature makes the O-class stars very bright and contributes to their bluish color.
Currently, their powerful stellar winds are sweeping away the remnants of their cocoons, which, when ionized, give the reflection nebula its visible color spectrum in the image.
Class O stars are stars with a fleeting life, quite different from our own. Due to their mass and high rate of nuclear fuel consumption, they have a short lifespan compared to other classes of stars, quickly (in astronomical terms) depleting their nuclear fuel and ending their existence as brilliant supernovae.
These stars are characterized by the presence of very strong spectral lines of ionized neutral hydrogen (known as H-alpha lines) and other lines of elements such as helium and nitrogen. The presence of these characteristic spectral lines helps astronomers identify and classify O-class stars.

NGC 6744 is an intermediate spiral galaxy about 30 million light-years away in the constellation Pavo. With its flocculent arms and elongated core it is considered to be a much larger (200,000 light year span) Milky Way analogue. Like the Milky Way the bright central region has a dense number of bright old yellow stars, with numerous star forming regions in the arms.

IMAGE DESCRIPTION AND DETAILS :

An LRGB Composition of Messier 94. Messier 94 (also known as NGC 4736) is a spiral galaxy in the mid-northern constellation Canes Venatici. It was discovered by Pierre Méchain in 1781 and catalogued by Charles Messier two days later. Although some references describe M94 as a barred spiral galaxy, the "bar" structure appears to be more oval-shaped. It is classified as having a low ionization nuclear emission region (LINER) nucleus. LINERs in general are characterized by optical spectra that reveal that ionised gas is present but the gas is only weakly ionized (i.e. the atoms are missing relatively few electrons).

​The galaxy has two ring structures - the inner ring with a diameter of about 5,400 light-years and an outer ring with a diameter of about 45,000 light-years. These rings appear to form at resonance points in the disk of the galaxy. The inner ring is the site of strong star formation activity and is sometimes referred to as a starburst ring. This star formation is fuelled by gas driven dynamically into the ring by the inner oval-shaped bar-like structure.

On Saturday, June 17, at 12:44 pm (UTC-3), I had the incredible opportunity to capture a massive yet delicate solar prominence situated on the northwest limb of the sun. This extraordinary plasma formation soared to an impressive height of approximately 100,000 km, with a width spanning over 150,000 km. Although its appearance was brief, its grandeur left a lasting impression.

Within the solar disk, my observation revealed the presence of 8 active regions, each adorned with sunspots of varying sizes. Additionally, captivating prominences surrounded the sun, showcasing their captivating structures.

The art of solar observation and photography constantly holds surprises, and this event was truly breathtaking. Such a magnificent prominence serves as a reminder of the awe-inspiring phenomenon our sun can exhibit!

To capture this sight, I used a 90mm aperture Coronado SolarMax II telescope, paired with a Player One Saturn-M SQR camera.

Image Description and Details :

NGC6946 - Fireworks Galaxy - Constellation Cepheus
NGC 6946 is located in the constellation Cepheus, bordering that of Cygnus. NGC 6946 is a spiral galaxy about 22 million light years away from us. Numerous supernovae have been observed in it, so much so that it is christened the "fireworks galaxy". It is an intermediate galaxy between spiral and barred spiral galaxies with a high level of star formation. It is believed to be a very active galaxy not only due to the presence of numerous nebulae, incubators of stars but also due to the presence of rivers of hydrogen (cold streams) which allow hydrogen to be distributed in such a way as to maintain the formation of new stars . It differs from our Milky Way precisely because of the greater star formation. It was discovered in 1798 by William Herschel, known for having, among other things (he is credited with identifying Uranus), discovered infrared rays.

This is an image of NGC 7497. It is an edge-on spiral galaxy about 60 million light years away in the constellation Pegasus. The nebula surrounding the galaxy is known as MBM 54 and is located about 1,000 light years away in the outer regions of our galaxy. These types of molecular clouds are found at high galactic latitudes (parts of the sky away from the plane of our Milky Way Galaxy). They are often referred to as galactic cirrus clouds or more commonly "Integrated Flux Nebulae" (IFN).

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.
