>>3119033okay, let's point out a few things
>your focus is a bit off>no PP at all>clouds>you've literally pointed the camera upwards and took a photo, this is not how it works unless you're going for real astro and photographing certain object on the skyiso 2000 sounds okay. use live view to focus and find a brightest star you can find. Also, from my (still not really vast) experience it's best to shoot night sky with the little bit of the moon, or right after the moon disappears behind the horizon. It gives a sky nice blue color, as opposed to crappy red glow from street lights. Also, find a nice landscape to put on the photo. Even without a proper subject, it's still better to have a landscape silhouette than just a sky.
Pic related was shoot with the assistance of the moon behind the horizon on iso either 1600 or 2000, yet look how nice the sky color is. Camera settings are one of least important aspects of astro, really. It's mostly about knowing where and when the sky should look the best.
