How dark can you go?

Today, or, more precisely, tonight I only had some very dark and even darker photos. How dark can you go? I think I overexceeded the limit but I didn't get a second chance with kids to adjust my settings. But: for the first time ever I used the timer and that's a tiny progress, too.

A miserable weather here! I bet the rest of the country is enjoying of some fresh new snow while we here are getting the sleet.
