Does the full moon glare in your Binoculars?


I have a pair of Nikon action 10x50 binoculars. On a full moon the glare through the lenses if really bad.
is this common? I know they are not fully multi coated. probably part of the problem.

    It is not about coating. The moon is just too bright for you.

    Full Moon is not a good time to observe the Moon. The Sun is directly overhead, and casts very little in the way of shadow, and consequently, much detail is lost. Better to observe two or three days on either side of the Full Moon.

    Well, …, the Full Moon is the worst phase to observe the moon in. At magnitude ~-12.7 it’s really bright and will quickly deplete your night vision. That’s probably why “glare” is bothering you so much. The best time to observe the moon is where there is a shadow on the surface. Viewing along the terminator of the shadow will give you the best views of lunar features that you could hope for. You really need that contrast to help distinguish useful features on the lunar surface.

    So, I don’t think it’s you’re coatings. Nikon Binoculars are generally a great pair of binoculars to own. Rather, I do think it’s your timing. Wait for a couple of days after Full moon and try viewing near the shadow terminator.

    As with the others, the full moon is just about the worst time you can look at it. Oddly enough, you could try wearing sunglasses, which would cut down on the brightness.

    The better times to look at the moon is when it is coming out of its new phase towards full, or past full going into new. Shadows from crater walls and mountains are long and makes finding stuff lots easier.

    One test that you can do with the moon and your binoculars, is to see if there is any image ghosting inside the binos. Sweep the binos from one side of the moon to the other. Do you see any false images? If so, then the binoculars have poor internal baffling, which helps to cut down on the internal reflections.

    And here’s an observing list of things to look for on the moon with your binoculars -
