The Williams Optics 25mm 2" eyepiece is a solid performer and an order of magnitude better than the 1.25" 25mm Possel that come standard on many telescopes. I would say its a good 2" Wide Angle eyepiece at a very reasonable price - very much worth the money. While the Williams 25mm 2" EP is a good eyepiece the Williams 40mm 2" EP is a special eyepiece .
Ocular optimo para focales mayores de F6. Tiene un uso de campos medianos como el doble cumulo de perseo. El ocular tiene una construcción muy bien terminada y con buenos materiales.
