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

Magnificent! How long an exposure?

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

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.
