Just because it is unedited does not mean that is how the human eye would see it.

No, the camera picks up a lot more light than the eye can, especially with a long (this was 20s) exposure. The limiting visual magnitude here is about 6.0, whereas the faintest stars captured in the shot are about magnitude 9. You can also see comet Lovejoy and M33 (barely), which I've never been able to spot with my eyes.

| Beautiful shot, as always Watsisname!

A dark sky looks far more impressive to the naked eye ;)Quote Watsisname ( ) No, the camera picks up a lot more light than the eye can, especially with a long (this was 20s) exposure.

Hm, with a NELM of +6 you should be able to distinguish M33. I did it myself under such conditions, with M33 being about 45 degrees over the horizon. Though averted vision was required.

Indeed it does. A truly dark sky even gives me an (obviously false) perception of depth to the sky, and I'm always amazed at how it can contain so many stars and yet still be so dark. Good old "Olber's paradox" mathematics for you.

If you could spot it from a flat 6 then I'm impressed. At magnitude 5.7 the contrast between M33 and the background sky is very low (as evident by the long exposure), and so it is a considered a difficult averted vision target. I've never managed it, but I have a very hard time spotting diffuse objects with such low surface brightnesses in general. A half magnitude or more difference makes it a lot easier.

I remember the first time I saw a truly dark sky. The first thing I thought, was that I could not blame those in the middle ages, who believed all the stars were located at the same distance, because that was my impression too!

I saw a star that I know have an apparent magnitude of about +6.1, and I saw M33 with averted vision. Very hard to see though, I was out for about 20 minutes before my eyes had got used to the darkness.

| First capture from a guy on reddit at /r/space, using his new solar telescope. (So not mine unfortunately)
That's hot in all different kinds of ways.

| I noticed a red dot next to Venus tonight. It's Mars (had to look it up). That might create a good picture. Has anyone had a go?

| I got this one the other day when they formed a trio with the Moon. Had some clouds though.

| Wow! Great shots. A pity with that aurora spoiling the view of the Milky Way.

| These are great shots! I wanna see the aurora one day but I'd need to do a bit of travelling. May I ask what camera and lens you used to capture these shots?

| Outstanding! It's not very often you can see both the Milky Way Centre and auroras at the same time
