This is a high-quality Antares 1.25 25mm Plossl eyepiece with focusable crosshairs (single), perfect for alignment and tracking. To obtain razor-sharp focusing of the crosshairs, merely turn the upper part of the eyepiece. Focus markings on the eyepiece barrel facilitate consistent focusing from session to session, no matter what the sky conditions. This reticle focusing feature - rarely available in competing crosshair eyepieces - is a great boon if your eyesight is not 20/20 and if you wear glasses.
Whether you want better Go-To, or more precise tracking, a crosshair eyepiece is a must. You can combine this eyepiece with a barlow lens for even higher power and more accurate alignment.
