Low Light Long Exposure Night Photography

Hello for those of you who have an interest in long exposure night photography please chime.  This is an open forum to share your techniques, equipment, and post processing secrets. 

I really love long exposure night photography.  I tend to use very low ISO's, aperture's between F8-11, and shutter speeds anywhere from 2 sec-5 minutes.  Of course this depends on the subject that I am capturing and other issues that us photographers deal with.

One of the issues I find myself facing the most when it comes to low light photography is also probably the most obvious, focusing issues.  At times, especially when I am doing landscape with barely any light I find that I can't find a happy medium when it comes to manual focusing.  I either have the foreground completely in focus and nothing else, or the situation is reversed.  Does anyone have a useful tactic, especially with regard to low light long exposure landscape photography to combat this issue?

With that being said I just posted some low light long exposure photos and I would appreciate it if you could take a look and give me some feedback.  If you like them, why?  If you don't like them, why not?

Respectfully,

Jason
