Explore Scientific 40mm 62° 氬氣防水目鏡 - 2" - EPWP6240LE-01

I was able to see all four of Jupiter's moons at once with this eyepiece—the 62-degree field made finding them effortless. The waterproofing gives me peace of mind during humid nights.

The 62-degree field makes sweeping the Milky Way feel effortless on my 8-inch scope, and the argon purging gives me total peace of mind during damp nights. Focus holds steady across the view, and the near-parfocal design means I rarely touch the knob between eyepieces.

I use this eyepiece on my 10-inch Dobsonian, and the argon purging gives me peace of mind during dewy nights—no fogging at all. The 62° field is wide and crisp, making globular clusters look like they’re floating in space. It’s a solid upgrade for deep-sky observing.
