Diopters For the PME Finders


New Member
Again I have purchased something without instructions! This time a +2 diopter. I cannot figure out weather it goes in front or begind the eyepiece glass that is already in there. Does anyone know?
The diopter goes in front of the existing eyepiece glass.

There should be a thin, black metal ring with two small notches on the outside of the existing eyepiece. Simply unscrew this ring, place the diopter on top (in front of) the existing eyepiece, and screw the ring back in.

Got it David! Apparently this is the wrong diopter as it still is clearer without it. Because the diopters are not labeled it would be easy for someone to put it in the wrong box. I bought it used from Ebay. Thanks for your help,
