Jakov, I like to keep the image as true to the original scene as possible. Bjorn is right, brightening it would make the picture look unnatural as this was taken around 1am.
Bjorn, I first became interested in trying the f/1.8 version when I saw the image you posted displaying it's spectacular starbursts. Which was also at f/11, so must have been that one. Was originally just going to go with the f/2.5 until I saw that post, thanks!
