مرشح كثافة محايد Baader Planetarium 1.25 بوصة 1.8 - FND2-1

The image stays sharp and pinpoint even with the light cut in half, which is exactly what I needed for lunar viewing. The multi-coating is clearly doing its job—no glare or ghosting at the eyepiece.

The thread on this filter is buttery smooth, and the multi-coating is visibly flawless — I can leave it in the eyepiece without ghosting on the Moon. It dims things just enough to keep detail sharp, which is exactly what I wanted for casual lunar viewing.

I’ve been using this 1.25" ND 1.8 filter for lunar observation and it cuts the glare perfectly without altering color—the multi-coating really makes a difference in clarity.
