Product Description

The Astro-Tech 4mm High Grade Plössl eyepiece is one of the most economically-priced and shortest focal length very high quality Plössl eyepieces available. It is designed for very high magnification lunar and planetary observing and for splitting close binary stars with virtually any telescope type. The 55° field of view of this Astro-Tech is surprisingly wide when compared with other Plössls in this focal length range.

The useable eye relief is very short and will severely vignette the field of view for eyeglass wearers. We can't recommend this eyepiece for those who must wear glasses while observing.

Purchased this and a couple of other eyepieces in this line and I am quite pleased with the quality as well as the value. While not the most expensive eyepiece, you might not know the difference without looking. (Posted on 10/23/2019)

This was a great deal when I bought it on sale. High quality, well constructed. It's just too much for either of my telescopes. (Posted on 8/26/2019)
