The 12.5mm illuminated reticle eye pieces are a pain to use, narrow apparent field of view , poor illuminator , small eye relief etc...,
My recommendation is to buy an Orion 20mm 70 degree illuminated reticle eye piece
A superior eye piece with wide field , more magnification, good eye relief and a very good illuminator
The additional cost is well worth it I can assure you
I think they are still available through Bintel
Cheers
