Explore Scientific 40mm 52° Argon-Purged Waterproof Eyepiece

With superior optics and a completely waterproof, argon-purged exterior, the Explore Scientific 40mm 52° Eyepiece exudes quality and value. The barrel has been argon-purged, making it waterproof and preventing moisture from entering optics. With a 52° field of view, you will notice a wide field that is flat even at the edge. This makes the eyepiece great for averted viewing. Add on EMD coatings, and you get a high-quality eyepiece for the price of a plossl.

The argon-purged barrel makes sure all internal optics stay dry and moisture-free. This means you can view the skies for hours in rain, snow, or dew. This also makes cleaning the 40mm 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.

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 30mm 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 40mm eyepiece is compatible with a wide variety of drawtubes and accessories with its 2" barrel. This textured barrel offers slip-resistant grip, even when wearing gloves.
