When I take my students out to do some star-hopping, we find that it takes about 1/2 hour in darkness for our eyes become fully adjusted. At this point we can begin to find very dim objects that we would otherwise not be able to see with any bright light source around. I find that my low power 405nm is perfect for this situation.
