The MEP-20-60 is a versatile 3x zoom eyepiece designed for use with MONARCH Fieldscopes.\n\nEffectively corrected chromatic aberration ensures high resolution and sharpness all the way to the periphery throughout the entire zoom range. Long eye relief gives a clear field of view even for eyeglass wearers, while turn-and-slide rubber eyecups make it easy to position eyes at the correct eye-point.\n\nMagnification is 20-60x when attached to MONARCH Fieldscope 82 series or 16-48x when attached to MONARCH Fieldscope 60 series.
