M13 is now at a good point, high up at night. A quick (very quick) look at this bauble.

Can you find the very small background galaxy in this image? It's at magnitude 18.

Very pretty tight agglomerations of many stars that are gravitationally
bound together and continue to get more tightly bound by flinging the
odd star out to infinity whilst the rest contract into towards the core.

M13 is a very bright example and easily found even by a novice star
hopper. Just down from eta Hercules about 1/3 the way to zeta.

Until they evaporate completely (which takes somewhat longer than the
current age of the Universe).

My goodness don't you and so many theoretical drones like you have your heads filled with rubbish in an era where imaging is king and interpretation rather than speculation rules.

Astronomy is an experience for the inspired and the inspiring as it connects the individual to the Universal in an intimate and almost innocent way insofar as judgements are deliberated upon normal faculties of motions.

So much to do and so few to do it.

I am sure you have Brexit on the brain and a EU globular cluster on your mind -

I see you over with the voodoo merchants in sci.astro.research, what the 'astro' stands for I have no idea but it certainly ain't astronomy, just theorists spinning their wheels .

Magnificent! How long an exposure?

Is it the streak about 1/5 across and just over half way up left side?

I quite like the little asterism near the bottom with two equal
brightness stars symmetrically either side of a brighter one making a
fake Saturn appearance. 1/3 across the bottom.

The exposure was 5 minutes, a single exposure.
Yes, the mag 18 galaxy is about half way up the left side.

Thanks for sharing your image.

Do you suppose the impertinent troll would be happier on sci.****forbrains?
None of them can produce their own images, to save themselves.
But they are very keen on [completely wrong] interpretation of YouTubeToothpaste.
It's a bit like pseudo-science, tea leaf reading with extreme delusions of grandeur.
Back in the good old days [which they worship] they'd be incarcerated for their own good.
These days they just call it Care in the Community and pray they keep taking their meds.

I normally leave the magnification crowd to their own devices but once the make-it-up-as-you-go-along theorists show up it strays into interpretative territory.

The childish never made the transformation into adults in matters of astronomy yet to all the world they appear like people of great learning, even in this matter.

"Cor. 2. And since these stars are liable to no sensible parallax from
the annual motion of the earth, they can have no force, because of
their immense distance, to produce any sensible effect in our system.
Not to mention that the fixed stars, every where promiscuously
dispersed in the heavens, by their contrary actions destroy their
mutual actions, by Prop. LXX, Book I."

That is pure rubbish conjured up in much the same way as Brown puts down in a post whatever is in his head . Forget parallax as that is a dog of a perspective and hinders the use of the background stars and is an obstruction to interpretative astronomy and especially proof of the Earth's orbital motion.
