      Hi,

      I bought a WO GT81 apo (5 element) and used it for imaging 3 times with great results.

      I would appreciate help in choosing a good imaging barlow for this type of telescope which has a flat field.

      I recently used an Antares 1.6X barlow, but found the image quality to be poor.


      Thank you,
      Sam
