TPO 9mm Plossl Eyepiece - 1.25"
The four element Plossl design is perhaps the most popular telescope eyepiece design on today's market and an all-around performer. The OPT Plossl provides excellent image quality, good eye relief and an apparent field of view of about 45 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. Each 4-element eyepiece is fully multi-coated for maximum contrast and has blackened lens edges to minimize internal reflections and the barrels are threaded to accept 1.25 inch filters.
The TPO 9mm Plossl Eyepiece is right in the optimum ballpark for high magnification for shorter focal length telescopes and serve as good planetary, double star and lunar details units.
