I'm an amateur photographer and was just looking at images of the Milky Way (Due to reading this last couple of posts on the thread) and some of the photographs look amazing and you can see the bright centre as illusrtated in many images too.
Like these for example
Then I came across this image. This photograph just wins. the only image which is going to beat this is a picture of the earth exploding or being eaten up by our sun.
Yep that last one is CGI. Like these for example

Astro photography is good fun but you need dark skies to pull it off ( you can in some places in the UK).
I have an astro workshop this friday at Aoraki dark sky reserve (gold standard, bortle scape 1-2).
This from a few weekends ago.

I do on the other hand hate you and am very very jealous
So, images like those above, can you see this type of stuff with the naked eye if there was absolutely no light pollution anywhere, or can you only see it through the camera after taking loads of layered images etc?
Would love to be able to see something like that, just don't know if it's possible from Earth.

Cameras are much more sensitive and expose for 30 seconds etc so pick up more than you can see

In a dark location I can easily make out the milky way with my eyes once they have adapted to the dark. It's about bright enough to read with just.

Cheers for the response. Cameras are much more sensitive and expose for 30 seconds etc so pick up more than you can see
I'll just have to find a very dark location sometime.
The human brain has trouble with big numbers, made worse by the fact that we go up in multiples of powers of ten (hundreds, thousand,million, etc).
It can help to express these in terms of time.
Imagine something happening one a second. For example I'm paying off the national debt at one pound a second.
1 pound in one second
10 pounds in 10 seconds (that's pretty good)
100 pounds in a minute and a half (roughly)
1 thousand pounds in16 minutes
1 million pounds in 11 days
1 billion pounds in 32 years
1 trillion pounds in 31,700 years
That puts large numbers in a form thet the human brain has some hope of comprehending.
