Great wide view
Pros:Lightweight,Compact
Cons: Comments:A matched pair of these eyepieces was included with my W/O binoviewer. In the binoviewer or used as a straight eyepiece, these are excellent eyepieces, nice crisp view. The best part is the field of view. Up to this point I only had a nice little collection of Plossls. This is my first experience with a wider FOV eyepiece, and I was immediately hooked on the 'looking through a porthole into outer space' experience. Great value for the price.
