Baader Planetarium 2 吋 ND 3.0 中性密度濾鏡 - FND3-2

The first thing I noticed was how smooth the glass surface is, and the multi-coating really does cut glare when I’m imaging the moon. Screwed it onto my 2" diagonal and the view stayed crisp with no color fringing, which is exactly what I needed for lunar shots.

Wasn’t sure the multi-coating would make a visible difference, but the image contrast on the Moon stayed crisp even at full aperture. It’s a solid 2” filter that threads smoothly and holds up well during long observing sessions.

The coating is flawless—no reflections or halos, and it dropped the glare on the Moon exactly as promised. Screws into my 2" diagonal snugly, and the dense glass feels solid enough to trust with my eyepiece.
