The four element Plossl design is perhaps the most popular telescope eyepiece design on today's market and an all-around performer. The Third Planet Optics Plossl provides excellent image quality, good eye relief and an apparent field of view of about 52 degrees. This well manufactured Plossl will deliver high contrast and pinpoint sharpness out to the edge of the field of view.
These Plossl eyepieces are a great value for the amateur astronomer. We get them directly from the manufacturer to save you money. Each 4-element eyepiece is fully multi-coated for maximum contrast and has blackened lens edges to minimize internal reflectionsand the barrels are threaded to accept 1.25" filters.
The TPO 25mm Plossl Eyepiece is a great extended field eyepiece for longer focal lengths: 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.
