Still happy with it. My third ever astrophotography attempt.

Messier 13 or M13, also designated NGC 6205 and sometimes called the Great Globular Cluster in Hercules or the Hercules Globular Cluster, is a globular cluster of several hundred thousand stars in the constellation of Hercules.
To capture this photograph I took 65 - 2 min sub frames for a total of 2 hours and 10 mins of exposure time.
Also shot 20 matching dark frames and 40 flat frames to calibrate the light frames with.
M13 was discovered by Edmond Halley in 1714, and catalogued by Charles Messier on June 1, 1764.

First serious image with my new SVBony SV555 - the image is so sharp that this is a 2x drizzled image, for 108 Megapixel at 1.6"/pixel.

I thought I would revisit M13 with my new CCD and am very pleased with the extra resolution and detail I was able to get over my DSLR. I am still amazed at how little noise there is which allows me to do a strong stretch. I am still struggling with the colours, but I am sure that will come. Thanks for looking.

This is the brightest globular cluster in the northern hemisphere, so bright that it is visible even to the naked eye.
About 23 thousand light years away from us, it contains several hundred thousand stars up to 14 billion years old, reaching a density of stars 500 times those we see in our sky.
Chosen at a time of bad weather and problems with my photographic setup, being very bright allowed me to achieve a good amount of data with relatively few shots, here the result with about 3 hours.

Messier 13, the Great Globular cluster in Hercules lies at a distance of 25000 lys from earth and contains over 100000 stars.
I captured this image from my driveway using an 8" Reflrctor telescope. It is a composite of 44 light frames along with matching darks and flats and a bias frame. Processed in PixInsight using drizzle integration.

Voici M13, le grand amas d’Hercule. C’est l’amas globulaire le plus spectaculaire du ciel de l’hémisphère nord. Visible à l’œil nu dans la constellation d’Hercule sous un bon ciel, car relativement proche de nous (25 AL), il regroupe plus de 500 000 étoiles !
Leur couleur indique leur température et leur âge : les étoiles rouges sont des étoiles vieilles et « froides », tandis que les étoiles bleues sont des étoiles jeunes et chaudes.
En 1974, le radiotélescope d’Arecibo transmit un message vers M13 pour révéler à une hypothétique vie extra-terrestre résidant dans l’amas l’existence des Hommes. Mais ce message n’y parviendra que dans 25000 ans, et il faudra attendre 25000 ans de plus pour recevoir une éventuelle réponse, si tant est que le message touche son but, compte-tenu de la vitesse de déplacement de M13…

The Great Cluster in the constellation Hercules – also known as Messier 13, or M13 – is the finest and brightest globular cluster in the Northern hemisphere. Like shiny flakes sparkling in a snow globe, over 100,000 stars whirl within the globular cluster M13. Located 25,000 light-years from Earth with an apparent magnitude of 5.8, this glittering metropolis of stars in the constellation Hercules can be spotted with a pair of binoculars most easily in July.
The English astronomer Edmond Halley, best known for recognizing the periodicity of the comet that bears his name, discovered M13 in 1714. When Charles Messier added M13 to his catalog in 1764, he was convinced that the nebulous object did not contain any stars at all. Because they are so densely packed together, the cluster’s individual stars were not resolved until 1779. Near the core of this cluster, the density of the stellar population is about a hundred times greater than the density in the neighborhood of our sun. These stars are so crowded that they can, at times, run into each other and even form a new star. The resulting “blue stragglers” appear to be younger than the other stars in their immediate vicinity and are of great scientific interest to astronomers.

....mettiamola così,di solito gli ammassi globulari si riprendono almeno con una focale di 1000 mm. o giù di lì,ma riprenderli con un telescopio di soli 390 mm. di focale per di più con una full frame la cosa diventa quasi impossibile risolvere le stelle nei pressi del nucleo...ma ho voluto provarci ugualmente!!

The very well know globular cluster M13. The second biggest one orbiting our galaxy, the Milky Way.
Globular clusters are regions of spaces densely packed with stars. There are a number of them orbiting around the Milky Way. M13 is about 145 light-years in diameter and 22,000 light years away (which is next door). It is composed of several hundred thousand stars, some of which are as old as the universe. Stars will sometimes collide and form new stars which are blue in color.
In 1974, in the hope of reaching potential extra-terrestrial civilizations, a message was sent towards the cluster with the help of the Arecibo radio-telescope. The message encoded information about the human race, DNA, atomic numbers, Earth's position and other information. There is very little chance the message will ever be heard as technologically advanced civilizations need a stable environment to develop such as what humans have enjoyed on this planet. Due the close proximity of stars in this cluster, collisions between them are likely happening often. As a result, planets around them are likely crushed or tossed around quite a bit making life very difficult to establish itself and evolve...
What I really find cool about the picture is the presence of a tiny galaxy next to the cluster. This galaxy is about 500 million light-years away. This means the photons coming from the galaxy I captured that night, had left the galaxy when life was barely walking out of the oceans on Earth...
Imaged with a ZWO 1600MM and a Celestron SCT 8inch and a calm and clear night.
This is a cluster of stars called M13. We took this while doing photometry in Astronomy class. You can see Andromeda in the upper right corner.
My first attempt at this with my C8 telescope, autoguided! Recollimating the scope has done wonders, nice, sharp images. Also, my guiding was much better last night compared to the last time I tried it with the 8".
About 145 light-years in diameter, M13 is composed of several hundred thousand stars, the brightest of which is a red giant, the variable star V11, with an apparent visual magnitude of 11.95. M13 is 22,200–25,000 light-years away from Earth.

This is a baseline image for my endeavor to autoguide a Meade LX850 (12" f/8) on a Losmandy G11 mount. I'll call this image "trick or treat" I just went through the while guiding and capture process accepting the guiding results, and accepted this image as is.
I have some to-do items to work on from the imaging session. I notice, especially when I pixel peek in other software, an odd shaped peak at about the 6 o'clock position of all of the stars. I know that collimation of the main scope was good, because I checked at the beginning of the session.

This is a single 120s luminance exposure.
Taken on 22 July 2015 in the middle of Chelmsford, Essex shortly after some of the street lights had gone out, quite a lot of LP still around and passing faint high cloud, originally took 10 lights but 4 were unacceptable due to cloud.
Skywatcher 120ED polar aligned on Celestron AVX with unmodded Canon 700D. Didn't have the EOS clip in due to not being able to find it at the time!
6 x 90 sec lights, no guiding
No darks, flats or bias applied even though I did take them. Also forgot to turn off the LCD screen on the Canon 700D and so I ended up with amp glow on the right hand side of picture, hence I have not stretched this stack further.

M13, also known as the Hercules Cluster, is a globular cluster located in the constellation of Hercules. It contains hundreds of thousands of stars, packed within a span of about 145 light-years. At over 11 billion years old, it is one of the brightest and closest globular clusters to Earth, visible to the naked eye under good conditions.
