David Y. ★★★★★ Oct 21, 2026

The 150° field of view is a game changer for my ASI120—I can actually track meteors across the whole sky now. Even at the short 2.1mm focal length, the image stays surprisingly crisp in the center.

Andrew O. ★★★★★ Oct 20, 2026

Swapped this onto my ASI120mc for all-sky meteor work, and the 150-degree field is a game changer for catching fast streaks. The 2.1mm focal length keeps stars sharp edge-to-edge, even at f/2. It does vignette slightly on the corners, but for the price, the sky coverage is unbeatable.

Aurora ★★★★★ Oct 18, 2026

That 150-degree field of view makes a huge difference—I can see way more of the sky now than with my old lens. The 2.1mm focal length really brings out the wider star fields I was hoping for with my ASI120.
