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.


Well, over here we just voted to allow mentally ill people have guns. As many guns as they want. I believe it's to insure gun worker jobs, because coal miners are losing theirs.
Also, in this country there are a lot of rattle snakes, so ya gotta be prepared. In fact this morning as I was about to put on my shoes, one of them popped out of my shoe and I grabbed my Bushmaster and shot it dead! Believe me! Upon closer examination of the carcass it turned out to be a centipede. Well, you know that you hafta impede those centipedes, dontcha?

Bushmaster? You midwesterners are real wusses. Out here in the west,
we use RPGs for pest control.

Well, we have small tactical nukes here, but we keep them safely in our basements and just bring 'em out for thinning buffalo herds.

LOL! Reminds me of my wife, when she bought a small basket on the flee market for $1. After she brought it home, put her hand in it to clean , she got stung by a small Scorpio inside. Her finger swollen up, looks like a sausage for few days.

Not quite. Mag 20 objects have been observable by ground based
telescopes for some 60-70 years now. And Hubble can see down to mag
30.

Not any more. Modern CCDs now available to amateurs using 18" scopes
allow photographs comparable with old Palomar emulsion plates and have
done for quite a while now. A good test is IC1296 in the field of M57.
Jack Schmidling nabbed it testing his new kit back in

http://schmidling.com/m57.htm

Web page doesn't give dates but here is the original saa thread. By then
there were colour cameras that could catch the faint galaxy in 18/8/1999

The wider world are getting a new fiction that coincides with a participant here talking about a star being flung away -

https://www.sciencedaily.com/release...0614091907.htm

Of course to make it interesting they link it to the demise of the great dinosaurs but these are all playthings of the imagination as Leibniz once remarked.

One of the most lovely insights that is most personal is that certain types of supernova don't represent the death of stars but rather a transition phase which give birth to solar systems, including our own. There is an extensive narrative behind this reasoning but unsuitable for a readership that can't be inspired or inspiring and who live of intellectual bling and speculative novelties.

That field (M57 and galaxy) is only about 3 arc minutes wide. It would take a very high-power, narrow-field eyepiece to exclude one or the other object. The galaxy is just very dim and if we aren't looking for an object, it's even harder to spot.
