1.25インチ ND 0.9 ニュートラルデンシティ ムーンフィルター (310245)

First night out with it, I noticed immediately how evenly it cuts the brightness across the whole disk—no weird color shifting, just a crisp, comfortable view. Even with my 8-inch scope, the moon's detail stayed sharp without that harsh halo making me squint.

I've been observing the moon for years without a filter, and this ND 0.9 really cuts down the harsh glare—now I can see craters clearly without squinting. The 1.25-inch size fits perfectly in my eyepiece, and the image stays sharp edge to edge.

First time using a moon filter and I’m surprised how much crisp detail it brought out in the craters while cutting down the harsh brightness. Makes viewing the full moon comfortable without washing out the surface texture.
