A real gem in the night sky, this globular star cluster is M13 (13th entry in Charles Messier's catalogue of deep sky objects), the Great Hercules Cluster in the northern hemisphere sky. It is visible to the naked eye as a fuzzy patch of light under a clear, dark sky. Located about 25,000 light-years away from Earth, this globular cluster is made up of several hundred thousand stars and occupies a region of space that measures around 150 light-years in diameter. The stars of M13 are about 12 billion years old, an age comparable to the age of the Universe itself (about 13.7 billion years).
Look at it with a small telescope and the view is filled with countless sparkling stars. With larger telescopes and in deep exposures the tremendous number of stars becomes evident. One can only imagine the view from a hypothetical planet around a star close to the center of M13, a night sky filled with thousands of stars brighter than the brightest stars in our own night sky.
The faint 12th-magnitude galaxy NGC 6207 can be seen below and to the left of M13. It is a spiral galaxy located about 40 million light years away that appears by chance close to M13. Between M13 and NGC 6207 lies another smaller and fainter galaxy - IC 4617, which is more than 10 times farther away than NGC 6207. Can you spot it?

Here's a wonderful patch of space, The Great Cluster in Hercules. 300,000 stars squashed into a ball, orbiting our galaxy. Estimated to be nearly 12 billion years old, almost as old as the universe. What would the night sky look like if you lived there? Does it ever get dark?
M13 or NGC6205 is a Globular Cluster located in Hercules - about 145 light-years in diameter, and it is composed of several hundred thousand stars, the brightest of which is the variable star V11 with an apparent magnitude of 11.95. Distance: M13 is about 25,000 light-years away from Earth and has an estimated mass of 600,000 solar masses.
Also in field are galaxies NGC 6207 & IC 4716
Note: The diffraction spikes on larger stars are due to the control/power wires for the Optec FastFocus C-11 SMFS focuser which focuses the telescope by moving the secondary mirror.

This is my most recent image of M13. It is a globular cluster in the Hercules constellation. It is about 20,000 lightyears away and contains somewhere around 400,000 stars, although I have heard estimates of up to 500,000 stars. It is one of my favorite objects to look at through an eyepiece and it is a relatively easy deep space object to photograph. Even though it is one of the brighter objects in the sky to image it can always can be better with time and patience.
I used a Sony A7RIII camera mounted on an Istar 140mm refractor. I picked the best 22 frames that were 60 second exposures stacked them and post processed them in Astropixelprocessor.
A relatively short capture of M13 from my remote observatory in Taxahaw, SC under gently light polluted Bortle 4 skies. M13 is one of the brightest star clusters visible from the Northern Hemisphere. Located 25,000 light-years from Earth, it is easily observed with a pair of binoculars as a fuzzy patch located near the center of the constellation of Hercules.

M13 Great Globular Cluster in Hercules
Had a few cloudless hours to grab an easy target. It is the first DSO I have imaged since November. Either my sky conditions have really deteriorated since November or there were some high thin clouds. Either way it was good to give the gear a run.
I tried something different and shot 200 Luminance filter subframes only 5 seconds each. I combined this with some RGB I shot in 2013 from my QHY23M and AT65. The large number of subframes really seemed to produce a much cleaner image. In a few months when it is clear again I will give 100+ subs a try again

I must admit that I am a little disappointed with this. I lost about 50% of my R frames due to poor tracking. Hence a weak R colour. Not really sure why. Maybe I will add some more to it ( maybe I won't) at some point.
M13 is about 145 light-years in diameter, and it is composed of several hundred thousand stars, the brightest of which is the variable star V11 with an apparent magnitude of 11.95. M13 is 25,100 light-years away from Earth.

Messier 13 (M13) is one of the most famous and brightest globular star clusters in the Northern Hemisphere.
It can easily be spotted with binoculars at the time of this posting and can even be detected with the naked eye in a dark sky.
It is the 13th entry in Charles Messier’s catalog of deep sky objects which he added in 1764, but it was actually discovered by Edmond Halley (of Halley’s Comet fame) in 1714.
A globular cluster is a ball of stars numbering in the hundred thousands, in this case about 300,000 stars in a ball about 150 light years in diameter. There are around 150 of these in our galaxy and they contain some of the oldest stars in the universe.
M13 is about 12-14 billion years old, but it is “only” 25,000 light years away in the Spring/ Summer constellation of Hercules.
The individual stars average about 1-1.5 light years apart, probably much closer in the core, perhaps as close as 0.1 light years.
The brightest reddish stars in the cluster are ancient red giants. These aging stars have expanded to many times their original diameters and cooled. The blue-white stars are the highest-temperature stars in the cluster.
