The larger the aperture, the more light that is gathered. The moon is bright through my binoculars, but I don’t need a filter. I’ve never used a filter in my 4.5″. But my 4.5 isn’t a very good scope. When I get up to my 6″ I pull out the moon filter on nights when the moon is or is near full. I still do not need it most of the time. When the moon is full it makes all the difference in the world. Over 6″ in aperture the filter becomes much more necessary.
So you must ask yourself, what scope are you using? How often do you want to study the full moon? For me it is worth the cost. It was so worth the cost it was the first filter I purchased. You will have to decide for yourself.
