      5.0 16mm UWAN - EP You Must Consider

      Pros:

      Quality Lenses

      Cons:

      Comments:

      I have compared to Nagler T-6 at star parties in my 8" SCT. Difficult to distinguish other than price. You must consider these premium wide field EPs. It really is a giant leap up from smaller AFOV EPs. Like all wide field EPs, they give a space walk view and reduce light pollution compared to EPs with the same field of view.

      Bottom Line: Would you recommend this item? Yes
