TPO 20mm SuperView Eyepiece - 1.25"
Just ask one of our Telescope Experts
TPO 20mm SuperView Eyepiece - 1.25"The Erfle eyepiece design 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.
Fully multi-coated four 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 1.25" filters.

I have the 50, 30 and 20 mm eyepieces. I am using them through an Orion 10 Astrograph Newtonian and I am very happy with them. They are very clear and the focus is easy. If you are looking for an eyepiece that performs well at an affordable price then consider these. I would purchase them again if something happened to the ones I have now.
