Customer Reviews (4.6 / 5 · 5 reviews)

John ★★★★★

The threads are smooth and it threads onto my focuser without any wobble. For a used filter, the glass is surprisingly clean with only a tiny dust speck I can't see in the eyepiece.

Grace C. ★★★★★

Even with a few small scuffs on the barrel, the threads are smooth and the glass is crystal clear—no scratches at all. This 1.25" filter locks onto my eyepiece perfectly and really cuts the city glow without washing out the stars.

Robert ★★★★★

I was a little hesitant buying used gear, but the planetary filter's coating looks flawless and it threads smoothly onto all my eyepieces. The 1.25" size is perfect for my scope, and it delivered crisp views of Jupiter's cloud bands on the first clear night.
