2 years ago I lacked the skills to produce what I call a good M13, I've been learning loads and experimenting even more, and my ever patient mate Mark, talked me through doing it right and this image is the result.
The guiding wasn't as good as I would have liked, iOptron still need to release their latest software, but it's getting there.
I deliberately try to frame my images differently when I remember and this is no exception.
This was imaged over two nights of the 12th & 13th May 2019, it was a bit blustery and with a bright moon, it is to my mind my best shot for now.
This is from Wiki: - M13 is about 145 light-years in diameter, and it 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 about 22,200 light-years away from Earth.
It wasn't until 1779 that the single stars in this globular cluster were resolved. Compared to the stars in the neighbourhood of the Sun, the stars in M13's stellar population are more than a hundred times denser. They are so densely packed together that they sometimes collide and produce new stars. The newly-formed, young stars, so-called "blue stragglers," are particularly interesting to astronomers.
The Arecibo message of 1974, which contained encoded information about the human race, DNA, atomic numbers, Earth's position and other information, was beamed from the Arecibo Observatory radio telescope towards M13 as an experiment in contacting potential extraterrestrial civilizations in the cluster. The cluster will move through space during the transit time; opinions differ as to whether or not the cluster will be in a position to receive the message by the time it arrives.
