      5.0 Eyepiece for star test

      Pros:

      Accurate,Lightweight,Compact

      Cons:

      Comments:

      The main purpose of purchasing this eyepiece is to perform star test with my telescope, against astigmatism.
      As a plossl eyepiece, this eyepiece benefits the advantage of simple construction,with good optics.
      With the aid of this eyepiece I found astigmatism caused by secondary mirror.
      Now I use this eyepiece fore planetary observing and star test, after collimation.

      5.0 High power, light price

      Pros:

      Quality Lenses,Lightweight,Easy to Use

      Cons:

      Comments:

      Excellent eyepiece for lunar and planetary viewing. Tight eye relief, but it's what I expected from a plossl design. I plan on using it to split some tight doubles when I get an EQ mount.
