The Pleiades (also known as the Seven Sisters, the Chioccetta or with the initials M45 in the catalog of Charles Messier) are an open cluster visible in the constellation of Taurus. This cluster, quite close (440 light years), has several stars visible to the naked eye; even if only four or five of the brightest stars are visible from city environments, twelve can already be counted from a darker place. All its components are surrounded by light reflection nebulae, especially observable in long exposure photographs taken with large telescopes.

Remarkable is that the stars of the Pleiades are really close to each other, have a common origin and are linked by gravity.

Given their distance, the stars visible between the Pleiades are much hotter than normal, and this is reflected in their color: they are blue or white giants; the cluster actually has hundreds of other stars, most of which are too distant and cold to be visible to the naked eye. The Pleiades are in fact a young cluster, with an estimated age of about 100 million years, and an expected life of only another 250 million years, as the stars are too far apart.

Because of their brilliance and proximity to each other, the brightest stars of the Pleiades have been known from antiquity: they have already been mentioned for example by Homer and Ptolemy. The Disc of Nebra, a bronze artifact from 1600 BC. found in the summer of 1999 in Nebra, Germany, it is one of the oldest known representations of the cosmos: in this disc the Pleiades are the third clearly distinguishable celestial object after the Sun and the Moon.

Since it was discovered that the stars are celestial bodies similar to the Sun, it was started to hypothesize that some stars were in some way related to each other; thanks to the study of proper motion and the scientific determination of the distances of the celestial bodies, it became clear that the Pleiades are really gravitationally bound and that they even have a common origin.

Another astro image - the clouds cleared last night, despite the forecast saying it would be overcast, so I stayed up all night and grabbed 6 hours or data collection on Andromeda. It's not finished as I need to collect further data to refine the image further and collect some data in the hydrogen (red) spectrum to show the nebulae within the spirals. So it's a work in process but still my best to date on this celestial object.

The Andromeda Galaxy (M31) is a barred spiral galaxy approximately 2.5 million light-years from Earth and the nearest major galaxy to the Milky Way. The galaxy's name stems from the area of Earth's sky in which it appears, the constellation of Andromeda.

The mass of the Andromeda Galaxy is of the same order of magnitude as that of the Milky Way, at 1 trillion solar masses and it has a diameter of about 220,000 light years.

The number of stars contained in the Andromeda Galaxy is estimated at one trillion, or roughly twice the number estimated for the Milky Way.

The Milky Way and Andromeda galaxies are expected to collide in around 4.5 billion years, merging to form a giant elliptical galaxy or a large lenticular galaxy.

Also visible in this shot are two satellite dwarf galaxies, M32 and M110 (the two other fuzzy star formations to the left and just below Andromeda).

M64 (NGC 4826) est une galaxie spirale située dans la constellation de la Chevelure de Bérénice. M64 est aussi connue sous les noms de galaxie de l'Œil noir, de galaxie de l'Œil poché, de galaxie de l’œil démoniaque ou encore de Beauté endormie. La galaxie M64 a été découverte par l'astronome britannique Edward Pigott le 23 mars 1779.

The Black Eye Galaxy (also called Sleeping Beauty Galaxy or Evil Eye Galaxy and designated Messier 64, M64, or NGC 4826) is a relatively isolated spiral galaxy 17 million light-years away in the mildly northern constellation of Coma Berenices. It was discovered by Edward Pigott in March 1779.

The Carina Nebula and Running Chicken Nebula from my Adelaide metro (Bortle 6) backyard. This is a combination of 13 stacked shots with a Optolong L-Pro filter and 1 shot with an Astronomik 12nm Ha filter as a luminance layer. Lots of issues, no lens collar meant I was getting trailing from differential flexure despite autoguiding. The light pollution meant even with the filter the blue channel was maxing out way too early. Horrible gradients over the frame (this is a crop). After huge amounts of adjustment the star colours are somewhat red. I will try the L-Pro again with a longer focal length (see if that stops the gradients) and will see if it helps when used without light pollution. Otherwise I am doing something very wrong here!

The Whirlpool Galaxy lies 28 million light-years from Earth and has an estimated diameter of 76,000 light-years.[17] Overall the galaxy is about 43% the size of the Milky Way. Its mass is estimated to be 160 billion solar masses,[18] or around 10.3% of the mass of Milky Way Galaxy.e saved with settings applied.

The "bubble" at the bottom of the image are two nebulae, NGC 6164 and NGC 6165. This bluish, soap bubble-like outer nebulosity is being pushed by the central star, an O7 supergiant, approximately 40 times more massive than our sun. Can you imagine such a thing?

2020 was an unusual year as we all know. It was a very busy year for me working on a 3D Animated Motion Capture Series and Music Video from home, and as a result I didn't manage to image much.

About the Nebula:

The Elephant's Trunk Nebula is a concentration of interstellar gas and dust with-in the much larger ionized gas region IC 1396 (located in the constellation Cepheus), about 2,400 light-years away from Earth.

Reprocessing old data:

I don't often do this, but decided to reprocess old data from 2017 in the SHO Palette (SII, Hα & OIII). IC 1396 was imaged on my first "budget friendly" Telescope (a 6" GSO Newtonian Astrograph). This was one of my first attempts at Narrowband Astrophotography, and the data that I captured back then was less than ideal, but a nice challenge to process. It is all part of the never ending lifelong learning experience.

I would like to revisit the IC 1396 region again, and image the very interesting surrounding structure with my wide-field APO Refractor Telescope. It is interesting to look back and see what you've learnt (which is why I've always kept my old learning images as a record).

L'astronome français Charles Messier a découvert cet amas globulaire et il l'a ajouté à son catalogue le 23 janvier 1779. Il l'a décrit comme une faible nébuleuse sans étoiles. Cette même nuit, il a découvert la comète de 1779 (C/1779 A1 (Bode)).

NOTE: This image was taken under a very polluted sky ( yellow-red zone ) and with high humidity. I am very impressed about how much signal I acquired and I have to say that the L-Pro filter worked very well against the light pollution! I had to integrate a lot because of the sky which was not so good.

Very satisfied of this result!

I always want to thank Terry Hancock, who is my teacher, for explaining me how to reach a good result even if I have acquired from a polluted sky and not only - I could not have reached all my latest results without his help! Thank you, Terry!

The Andromeda Galaxy (M31) is a barred spiral galaxy approximately 2.5 million light-years from Earth and the nearest major galaxy to the Milky Way. The galaxy's name stems from the area of Earth's sky in which it appears, the constellation of Andromeda.

The mass of the Andromeda Galaxy is of the same order of magnitude as that of the Milky Way, at 1 trillion solar masses and it has a diameter of about 220,000 light years.

The number of stars contained in the Andromeda Galaxy is estimated at one trillion, or roughly twice the number estimated for the Milky Way.

The Milky Way and Andromeda galaxies are expected to collide in around 4.5 billion years, merging to form a giant elliptical galaxy or a large lenticular galaxy.

Also visible in this shot are two satellite dwarf galaxies, M32 and M110 (the two other fuzzy star formations to the left and just below Andromeda).

M13 ou Messier 13, aussi catalogué NGC 6205 et très souvent appelé le Grand Amas d'Hercule, est un amas globulaire situé dans la constellation d'Hercule. Il est parmi les objets les plus imposants du catalogue Messier et il a été découvert par Edmond Halley en 17145. Charles Messier a ajouté cet amas dans son catalogue le 1er juin 17646. Les étoiles individuelles de M13 ont été résolues pour la première fois7 le 22 août 17998 par William Herschel.
