This MK25 Fixed-Power Eyepiece from Hawke Optics replaces the stock zoom eyepiece that came with your Nature Trek spotting scope to provide a single magnification that matches the minimum power of the zoom. The advantage of using a fixed power eyepiece is that they offer a wider field of view over zoom eyepieces with a reduced number of glass elements, which increases light transmission, so images are brighter. Fixed-power eyepieces also simplify digiscoping setup by eliminating zoom rings and the need for constant refocusing.
