Tecnosky Planetary ED 25 mm Eyepiece

Overview
The Tecnosky Planetary ED 25 mm eyepiece is ideal for wide-field, low-power observation. With its 5-element optical design and ED (Extra Low Dispersion) glass, it offers high color fidelity and excellent light transmission. The generous 60° apparent field is perfect for viewing extended nebulae, open clusters, or sweeping the lunar surface. The 16 mm eye relief and twist-up eyecup provide excellent comfort for extended viewing sessions and make it a great choice for eyeglass wearers or as a finder eyepiece.
