100° Optimus 目鏡 13.5mm (1.25/2吋)

After years of struggling with cheap eyepieces, the sharpness across the entire field on my reflector is a game-changer for deep sky observing. The generous 2-inch barrel makes framing open clusters feel effortless.

The 13.5mm gives such a crisp, wide view of the Orion Nebula in my refractor — the eye relief is generous enough for glasses. It’s become my go-to for sweeping star fields at medium power.

Finally got this for my 12" reflector and the eye relief is incredibly comfortable, even for someone who wears glasses. The 13.5 mm focal length gives crisp, bright views of globular clusters that pop against the dark sky.
