    TPO 30mm 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 30mm 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.

    Questions & Answers

    Ask a Question
    • What is the field stop diameter of this eyepiece?

      The manufacturer does not list an optical field stop diameter, but measuring the mechanical field stop (the retaining ring holding in the lowest element) gives a value of 37mm, which is consistent with a wide angle 30mm 2" eyepiece.
