Hi Leo,
please see my PM.
The problem I see is trying to also get low power use with these BV'ers. I really see Seibert Optics as being your only solution, whether you are happy with 1.25X as the lowest magnification factor or lower at around 1X. Otherwise, you would have to look at getting a different BV (Denk perhaps, to get around 1.2 or 1.3X).
