What is the best way to photograph the March blood moon? 

Unlike during a solar eclipse, no special safety precautions are necessary – it's perfectly safe to look at the moon (in or out of a lunar eclipse) with the naked eye. A pair of even low-power binoculars will certainly help show the moon in more detail. For photographing the moon, I would recommend a camera with some optical zoom – the moon is only about 0.5 degrees across. Because of the low lighting conditions, a tripod or other support would be helpful since a longer exposure time will be needed.
