Hey there, I am simply looking for a 3X MICROSCOPE EYEPIECE BARLOW LENS for use with my microscope. I am making compost tea and would like to see what I'm making. Does anyone know where i can find one of these as well as a 2x one? I have found tons for telescopes and on microbeman's web page it has where to get it but they are out of stock. I would prefer to order both of these lenses from the same place. Thank you for any replies!!
