Explore Scientific 20mm 52° Argon-Purged Waterproof Eyepiece


Whether it's observing the planets or averted viewing for faint, deep-sky objects, the Explore Scientific 52° Series eyepieces are an all-around excellent choice. View wispy nebulae with ease! This 20mm eyepiece provides high contrast and a notable flat field even at the edge of field. Bright, clear views against a wide field are achieved with the EMD-coated optics and a 52° field of view.


The 20mm eyepiece is compatible with a wide variety of drawtubes and accessories with its 1.25" barrel. This 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 20mm 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.
