Yes Chris that`s the post I was referring to. My wrapping the objective cylindrical paper has the length of the objective wd, unfortunately the thickness of my diffuser white foam is forbidding light from getting through it (I was thinking to attempt this idea but when I received the real thing I found out that it was very thick for that kind of work). Your idea with a small peace of tape in frond of the objective is very helpful and if my current way did not work I will embrace it.
I can`t understand how I`ll place " shiny surfaces on the INSIDE of the tubes & rear end of the lens" (!)I hope you've attended to shiny surfaces on the INSIDE of the tubes & rear end of the lens
I am already thinking that.Ordinary paper is better. A second sheet, with a separation between them, adds significantly to diffusion.
