Great job Jessy, good exposure considering the earth was lit. Care to share your metadata?

Nice Shots Jessy.
As you're already exposing for that Long and desire an even longer exposure time I would shoot at a smaller aperture than 3.2 as that would have given you much more deapth of field. You still got a decent DOF at 3.2 as your focal distance was really big (which is the second factor that afftects your DOF in addition to Aperture and focal length of your lens). Hyperfocal distance might still help you but just using a smaller DOF would be great to start with. I'm seeing some smudges above that mountain?
Glad you chimed in here. It was your shot of the tree on the hill at night that has got me to go out the two times so far that I've been night shooting. I think this time got some results that I am, for the most part, happy with. But I know I need to improve. Now that I know my 11-16 lens looks fairly nice i'm going to try my hand at perfecting focusing and timing.The problem with a longer exposure is that the stars will streak. That's fine if that's what you're after but at 13mm you can get away with 30 seconds and still have the stars fairly sharp. Virtually the entire scene is at infinity. I'd like have shot it with a similar aperture.

Thanks for the kind words, aquariumclown I don't know why you're getting the wrong info. Everything is right except that it was a 40sec exposure. I don't know where I spot metered because I was using manual focus set to infinity. I really need to learn how to use hyperfocal distance. I think that's why my foreground is so soft. I did some sneaky post processing to get the foreground lighter. In light room there is a graduating filter that is supposed to be used to darken skies. Well, i used it to lighten the earth instead.![]()
