Product Description
The 12mm Vernonscope Brandon "flat top" eyepiece is designed for high power use with any telescope type, at focal ratios f/7 and above. It provides highly detailed/high contrast close-up lunar, planetary, star cluster, and binary star observing. With shorter focal length scopes, down to f/4, it is still exceptionally sharp at the center of the field (although less so at the edges at these focal ratios).

I've been using a vintage version of this eyepiece for many years. It provides sharp views with great contrast. It also barlows very well. It weighs nearly nothing, so it will not upset your scope's balance. It performs best with f/7 and higher focal ratios. (Posted on 10/8/2018)

This is one of my main go-to eyepieces for high magnification views of the moon & planets. Provides sharp views with high contrast, and it barlows well too. (Posted on 10/6/2018)
