4x and 10x are my favorites and I allways wanted to try a reversed microscope for observing pond flora and fauna without a cover glass. And now I can do this in the field. When I receive it I will post some pictures. Snow and ice next winter could be fun also. I hope I can fix polarizing filters and halfwave plates on the trekker. Toine
