POFET Sun Filter for Eyepieces
Buy on Amazon
The POFET Astronomical Telescope Sun Filter is a full-aluminum solar filter designed to fit standard 0.965-inch eyepieces, allowing amateur astronomers to safely observe the sun. It uses a threaded connection for a secure fit and blocks the vast majority of harmful solar radiation. While it serves its basic purpose well, it is best suited for casual or beginner use rather than serious solar observation requiring high-contrast detail.
