So f 2.0 basically lets in twice the light of f 2.8.
Longer exposures are good but can introduce star trails
iso 2000 used to be an instant recipe for noise but sensors are getting better. Noise reduction is getting better too.

That is a great shot. Unfortunately, I only have one lens. Its a Sony 18-200 zoom and only goes down to f3.5.
