Explore Scientific 30mm 52° Argon-Purged Waterproof Eyepiece

Enjoy premium optics for the cost of a Plossl with this Explore Scientific 30mm 52° Series Eyepiece! With the 52° Series Eyepieces, planets will appear brighter, star clusters appear sharp, and nebulae details pop. That's the beauty of the 52° Series Eyepieces. EMD coatings to expose faint, deep-sky objects with bright clarity against a dark sky. The flat field even at the edge makes the 30mm eyepiece excellent for averted viewing, which is crucial when observing dim deep-sky objects such as nebulae.

The 2" barrel makes the 30mm eyepiece compatible with many drawtubes and accessories. The textured barrel offers slip-resistant grip, even when wearing gloves.

This Explore Scientific eyepiece features an argon-purged, waterproof exterior that protects internal elements from moisture. In fact, internal elements will remain as pristine as the day they were assembled. This also makes cleaning the 30mm 52° eyepiece effortless. There is no risk of cleaning solution migrating from the top of the lens and seeping around edges to be trapped in between elements.

Customer Reviews (4.6 / 5 · 5 reviews)

Victoria Q. ★★★★★

The eye relief is generous enough that I can see the full field even with glasses on, and the argon purging gives me real peace of mind during humid nights. Focus is crisp right to the edge of the 52° view.

Claire ★★★★★

Waited a month for clear skies to finally try this out, and the 30mm focal length with that 52° field makes the Pleiades look absolutely stunning—sharp right to the edge. I was also impressed how it stays fog-free during a chilly dew-heavy night, which is exactly what the argon purge is supposed to

Natalie ★★★★★

The argon purging was the selling point for me, and it’s reassuring knowing moisture won’t get inside even in damp conditions. Views of the moon are crisp and bright, and the wide 52° field makes sweeping starfields a breeze. Worth every penny over the stock eyepiece.
