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.

United StatesIt's a good eyepiece especially the price.
United StatesVery happy with this purchase. This is a great eyepiece. The Erfle design is dated, but it was a super wide field design years ago and it certainly works well today. Hard to beat for the money!
United StatesIf you want the widest possible field of view from a 1.25 inch diameter ocular, the TPO 30mm fills this need. You can go with a longer focal length eyepiece, but they all have narrower apparent fields of view. You get a "looking through a tunnel effect." If you go with 20 to 24mm ultra wide angle, you get edge distortions. The 30mm is a perfect compromise: a fairly wide apparent field of view with pinpoint star images to the very edge of the field.
United StatesSo far I really like this eyepiece. this is the first time buying a 2 inch eyepiece. It's a good eyepiece for not a lot of money.
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.
Very good eyepiece for the price and the performance. Has a wide field of view and is very sharp focus on the objects without any fall off on the edges. Recommend this to novices as well as experienced astronomers.
