Third Planet Optics 42mm Superview Eyepiece - 2"

The Erfle eyepiece design consist of five or six elements and was created solely for an ultra wide field of view – such as 60 to 70 degrees. At low powers it provides impressive deep sky views – huge swatches of sky with contrasty backgrounds and pinpoint stars. Galaxies and nebulae are framed by the fields in which they lay. However, we'll be honest... at high magnification the image sharpness can become distorted at the edges of some manufacturer designs in some telescopes without corrective measures. Once considered only the domain of observatory-class and research-grade telescopes, the 2" eyepiece is now frequently offered as standard equipment with deluxe model telescopes. Capable of delivering brighter, higher contrast images, better eye relief and a wider field of view, 2" eyepieces are the premium by which all others are judged.

Fully multi-coated five element optics with blackened edges to minimize light reflection while maximizing contrast and light transmission. All SuperView eyepieces have a full 20mm of eye relief, making them a good choice for everyone, even those who wear eyeglasses. With impressive quality and appearance, the SuperView wide-field eyepieces feature a flawless chrome and black anodized barrel with a rubber eyecup and grip. The barrels are threaded to accept 2" filters. The TPO 42mm Superview Eyepiece is a great extended field eyepiece for longer focal length – good for large nebula and open clusters. For shorter focal length, they are fantastic for large objects such as the Orion nebula, views of the full lunar disc, large open clusters and more. This multi-purpose magnification range also makes for good "locator" eyepieces in all focal lengths. They are also well suited to shorter focal length telescopes for extended views and large, starry fields.

"I had the chance to use them last night and I must say I was skeptical due to their cost but I am certainly pleased with their performance thus far. I am amazed at how inexpensive these eyepieces are, you guys REALLY hit a homerun with this one!!" --M. Taylor, Palmdale, CA

Favorite eyepiece for wide field viewing, sharp.
This is my favorite eyepiece for wide field viewing. It provides a very sharp image and is easy to use. Use it on my SC11 Edge.

Recommend it to anyone needing a wide field of view especially if you are a novice at the art of astronomy.

42mm Superview
This has become my favorite eyepiece. Sharp to the edges on an f/6.2 ED refractor. Everyone says great things about the 30mm which I like too but the 42mm is sharper on my scope.

42mm Superview
Very nice lens, especially considering the price. The outer edges loose some sharpness but most lenses do. In the majority of the view these are crystal clear.
