Astro-Tech 4mm 1.25" Value Line Plössl

This 4mm Astro-Tech fully-multicoated Value Line Plössl is one of the shortest focal length and most economically-priced Plössl eyepieces available. It's designed for very high magnification lunar and planetary observing and for splitting close binary stars. Short eye relief will vignette the field of view for eyeglass wearers, so we can't recommend this eyepiece for those who must wear glasses while observing. However, vignetting of the edges of the field shouldn't be an issue when observing small objects, such as planets, and when splitting binary stars.
