Acros is unsurpassed for night shooting. I've used it extensively and have attended workshops with the above-mentioned Lance Kemig. Great guy, great knowledge. Most of my shots are done for about 5-10 minutes at f/5,6 depending on how much ambient light there is.

Here's a few examples of my work with Acros at night:
