Explore Scientific 4.5mm 52° Argon-Purged Waterproof Eyepiece
With Explore Scientific's 4.5mm 52° Series eyepiece, you will see the night sky like never before. Faint objects pop against a dark sky thanks to the EMD coatings. The flat field even at the edge makes the 4.5mm eyepiece excellent for averted viewing, which is crucial when observing dim deep-sky objects such as nebulae.
The 1.25" barrel makes the 4.5mm 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 4.5mm 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.
