3. Use binoculars: they’ll show subtle details and colours
NLC displays are beautiful to the naked eye but they look even better through a pair of binoculars. The same binoculars you use to look at the Pleiades, M31, and the phases of the Moon will give you very clear views of the subtle shapes, structures and forms NLCs can take, and will enhance their lovely colours too. They will also help you see how bright NLC displays change shape through the night. And they are extremely useful for helping you spot the first faint signs of a display before it becomes obvious to the naked eye.
