There is a fair amount of blotchiness in the blank areas of the sky but judge for yourself whether you think the image is useable. I propped the camera on a wall and set the self-timer. Then it is just a question of half-pressing to get focus, and then completing the press on the shutter and making sure I was not in the scene.
I desaturated the image more or less completely, to get rid of the orange glow from the streetlights.
