      5.0 Provides nice views with my PST

      Pros:

      Cons:

      Comments:

      I purchased this to provide a higher power image with my Coronado PST than the stock 18mm Plossl supplied. While I have not compared the 12mm CEMAX to a comparable focal length eyepiece, I'm happy with the views this eyepiece delivers.

      4.0 Not sure if it offers an advantage

      Pros:

      Lightweight,Strong Construction,Compact,Quality Lenses,Easy to Use

      Cons:

      Comments:

      I don't really see a huge difference in useing this in my PST over a good general purpose plossl, say a TeleVue. However it performs well within the limits of the PST's limited 40mm aperture. Maybe in a larger solar scope the difference would be more noticeable.
      However they are fairly inexpensive so I have no regrets buying this.
