This 25mm eyepiece is perfect for low power scanning and to locate objects in the sky. This eyepiece is also perfect for scopes that come with only a high-power eyepiece, such as the 4SE.

The Plössl eyepiece results in crisp, clear viewing. It provides edge-of-field sharpness, low astigmatism and low spherical aberration.

The multi-coated optics allows for optimum image contrast and light transmission

The eyeguard folds down for people who wear glasses, shielding them from coming into contact with the metal eyepiece housing.

To calculate the magnification of this eyepiece, use the following formula: telescope focal length (mm) / eyepiece focal length (mm). For example, for a 640mm focal length and a 6mm eyepiece, the magnification is 106.7x (640 / 6 = 106.7). Please keep in mind that magnification also depends upon the lowest / highest useful magnification of the telescope. Check out individual telescope pages for highest / lowest useful magnification calculations
