      1.0 Don't buy this filter

      Pros:

      Compact,Strong Construction,Lightweight

      Cons:

      Poor Lens Quality,Not Removing Purple Fring

      Comments:

      The item was purchased for removing the achromatic aberration of a 120mm achromat refractor. Even though I didn't expect it to remove all the abberation, I was very much surprised to see that the aberration was not affected at all by the presence of this filter.
      Not recommended!
